Plants essays
Plants essays Fertilizer has played an important role in the health and growth of plants since the beginning of time. Fertilizer has helped farmers and million of people across the world to grow healthy plants that they could sell to the public. It does not have to be sold in bags to be considered fertilizer. Even a banana peal is fertilizer because it promotes the growth and helps improve the health of the plant. For plants to have a successful life they need to be supplied with various types and amounts of nutrients which is sufficiently provided by fertilizers (Secrets to great soil, 1998). There are two types on nutrients that are absorbed and used by plants(Improving the soil, 1996). Those two are macronutrients and micronutrients(Improving the soil, 1996). Micronutrients are the types of nutrients that are used less by plants because they are not as essential for good health(Improving the soil, 1996). They help the plant grow healthy, but the plant can live without them. Some types of micronutrients include calcium, magnesium, sulfur, boron, and manganese (Easy Compost,1997). Plants use macronutrients more frequently than micronutrients (Espoma, 2002). They are necessary and much more essential for the growth of plants than micronutrients (Espoma, 2002).. Macronutrients unlike micronutrients are extremely important for the plants life(Improving the soil, 1996). Without them a plant would most certainly die (Espoma, 2002). . These nutrients are in high demand. They are nitrogen, phosphorus, and potassium(Improving the soil, 1996). Phosphorus is one of the most vital nutrients that a plant needs(Secrets to great soil, 1998). It has a great amount of important role that it fulfills that helps maintain the plants health. One essential role that phosphorus plays in the development of plants is the improvement of its immune system(Secrets to great soil, 1998).. Just like humans, plants can also get ill. That is just one of the many...

Characteristics of a 21st-Century Teacher
Characteristics of a 21st-Century Teacher What does a 21st-century teacher look like to you? You may have heard this popular buzzword thrown around your school or on the news, but do you know what a modern-day educator really looks like? Beyond the obvious of being up-to-date on the latest in technology, they can have the characteristics of a facilitator, a contributor, or even an integrator. Here are six more key characteristics of a 21st-century educator. Theyre Adaptive They are able to adapt to whatever comes there way. Being a teacher in todays world means that you have to adapt to the ever-changing tools and changes that are being implemented in the schools. Smartboards are replacing chalkboards and tablets are replacing textbooks and a 21st-century teacher needs to be okay with that. Lifelong Learners These educators dont just expect their students to be a lifelong learner, but they are as well. They stay up-to-date with current educational trends and technology and know how to tweak their old lesson plans from years before to make them more current. Are Tech Savvy Technology is changing at a rapid pace and that means that a 21st-century teacher is right along for the ride. The latest technology, whether its for lessons or grading, will allow the teacher and student to be able to learn better and faster. An effective teacher knows that learning about the latest gadget can truly transform their students education, so they are not just current on the new trends, but really know how to master them. Know How to Collaborate An effective 21st-century educator must be able to collaborate and work well within a team. Over the past decade, this important skill has grown quite rapidly in schools. Learning is deemed to be more effective when you can share your ideas and knowledge with others. Sharing your expertise and experience, and communicating and learning from others is an important part of the learning and teaching process. Are Forward Thinking An effective 21st-century educator thinks about their students future and is aware of the career opportunities that may arise from them. They are always planning to ensure that no child gets left behind so they focus on preparing todays children for whats to come in the future. Are Advocates for the Profession They are an advocate not only for their students but their profession. Todays teachers are being watched with a close eye because of all of the changes in curriculum and the Common Core. Instead of sitting back, a 21st-century teacher takes a stand for their themselves and their profession. They pay close attention to what is going on in education and they address these issues head-on. They also advocate for their students. Todays classrooms are filled with children who need someone to look out for them, give them advice, encouragement, and a listening ear. Effective teachers share their knowledge and expertise and act as a role model for their students. 21st-century teaching means teaching as you have always taught but with todays tools and technology. It means utilizing everything that is important in todays world so that students will be able to live and prosper in todays economy, as well as having the ability to guide students and to prepare them for the future.

Christianity and the World of Faith Essay Example | Topics and Well Written Essays - 500 words
Christianity and the World of Faith - Essay Example Same is the case with love and tolerance which needs to be set in free so that people can understand how it is essential to inculcate a society which bases itself on growth and productivity of its own people. If they interact freely, it is taken as a plus point, and even Christianity accepts it with both arms wide open. Similarly, making education and healthcare free throughout the world will help the cause of any society of the world and hence help us get across the dictum of difficulties that have more bearing on the lives of the people that are seen possible (Rolfe, 2004). I opine that Christianity allows people to live freely and understand the real value of love, tolerance, compassion, and empathy. Christianity helps the people to evolve in a positive fashion which indeed is a good thing. Hence I see these three issues currently being signed for the different societies that exist within the world in the present times. My own core beliefs regarding Christianity surround the basis of doing well on to others so that it comes back in some form. Also, believe in God that he knows about everything and that Jesus was the noblest of men amongst all mankind. I base my beliefs on Christianity with what I have learned over the years as well as what my elders have told me over the years. I have seen devoted Christians during my lifetime who have always believed the basis of their religion because they tend to feel it this way. I am confident that Christians all over the world are proactively driven to bring goodness forward and this is one aspect that has been documented time and again (Emmett, 2011). From my perspective, Christianity is very close to being good to one’s own self as well as to the people who come in contact with this individual. I feel confident about Christianity because it provides peace of mind and heart.Â

Property and violent crime; a comparison of a8 migrants with uk citizens.investigate crime rates - Essay Example What if these facilities could miss out in a hall those students stays in what could happen? If such a scenario occurs, the students will therefore quit to be in that environment and look for a better place off campus where needs would be catered for. Westminster business school students have been raising opinions on the students living halls and comparing it to the private accommodation in central London. Tabling some of the opinions, advantages and disadvantages of the two students residing places came up in conjunction to the timing references and motivation factors. Therefore, in order to analyze their opinions they give on the advantages of living in both private and campus halls they came up with these: The students also enjoy the school facilities and are in an environment suitable for their studies with fewer distractions ("Why live in the residence halls? :: Residence Life and Student Housing | The University of New Mexico," n.d.). However, despite of the gainful advantages that the students encounter in these premises, there are also disadvantages that come along with them. For this instance, comparison of both private and university halls opinions give in to the presentation. In private apartments, not all are students and so it comes with greater responsibility of taking of one’s duties and bills and considering other people in the same place thus, lots of noise is minimal and other quire college behavior. In this instance, the private hall students are able to take responsibility at their own, which reflects in their future unlike students in university halls. Most of private apartments are costly hence students may share the rooms which comes with a sober decision making of who your friends are, and again these private goes all year round that means during summer break the student will need to pay for them. Transportation is also a student’s responsibility especially where it is not available it may get to some

Essay on Light and Dark in Antigone -- Antigone essays
Use of Light and Dark in Antigone  The "Golden Age" of Greece is noted for its many contributions to the creative world, especially in its development of the play. These performances strived to emphasize Greek morals, and were produced principally for this purpose. Antigone, by Sophocles, is typical. The moral focused on in Antigone is the conflict between physis (nature) and nomos (law), with physis ultimately presiding over nomos. Throughout Antigone, King Creon is a symbol for nomos, while Antigone stands on the side of physis. To portray these ideas, light and dark images are used as a recurring motif to reinforce the theme. Light is used to show something good that is happening, whereas dark is utilized to show something of which the gods disapprove. Following with tradition, this play uses light to portray what is right in the eyes of the chorus and darkness to reproach the other side. As the play is carried out, the chorus is constantly changing its opinions, first believing in the actions of Creon with respect to nomos, then unsure of what to believe, and finally seeing that Antigone's actions are more consistent with the morality of the gods and the truths of physis. Light and darkness are used to support in an emotional way the action of whoever the chorus is siding with at these various stages of the play. It is clear that at the beginning of Antigone, the chorus favors the actions of Creon, or nomos. This is shown as Creon's intentions and retribution towards Polyneices are justified by jovial words and imagery involving light. In the battle between Eteocles and Polyneices, although both leaders were killed, Eteocles' army was the victor. To show that this was positive in the eyes of the gods, the first lin... ... with connection to nomos was too high, and images referring to him are now dark and dismal. The play ends as the gods have turned their shoulder on Creon, and have made their final decision that Antigone is ultimately in the right. Because the sole purpose of Antigone is to get a moral point across, the parallels between light and dark and physis and nomos are associated together, and used metaphorically to add diversity and imagery to an otherwise redundant script. In the first scenes, these light and dark images show the reign of Creon. These are followed by the indistinct and ironic middle scenes, and end with the gods choosing Antigone's actions over Creon's, leaving Creon spiritually dead and paying for his poor choices and conduct. These are very effective techniques, which allow Sophocles to more fully develop his play, and give it a more emotional edge.

Superhero and Children
Lauren Lee                                                                                  February 25, 2013 English 101                                                                               Mr. Simmes Exemplification Essay To possess a human body, transcendental powers, and victory over evil villains are only a few characteristics of a superhero. These traits are the personification of what society has indicated to be the perfect man; or, depending on which superhero, a woman.Many superhero fans begin as children and often remain intrigued into adulthood; from wearing their uniform, to owning every one of their movies, to becoming a superhero, themselves. However, becoming a superhero is an obvious impossibility. These supernatural beings have the ability to fly, master the intelligence of villains, lift the heaviest objects, and jump off the highest buildings with no harm being done. It is the ideals of becoming someone great, which superheroes portray, that influence children and enhance their yearning to imitate the superhero’s image and actions.A superhero’s immense strength, chiseled toned body, and sharp intelligence are a few attributes that provoke fans to admire and idolize these beings. Many parents believe that children’s aggressive behavior is uncontrollable but it is also a result from the vigorously powerful superheroes that act as role models to children as they are growing up. Superheroes incredible strength has led them to victory over the biggest and strongest of enemies.I interviewed my acquaintance, Jon Wall, a senior at McNeese State University, who has an admiration for Superman, and he said, â€Å"From watching Superman, I thought I could prove my strength by defeating other kids. This did not mean that I went and tried to beat everyone up. Instead, I tried to be better than others at everything. I would try to hang on the monkey bars the longest, be the person who got picked first for any sport, and wrestle anyone to submission. †he continued, â€Å"Although my behavior sometimes got too aggressive, and got me in trouble, it always seemed to make me feel like more of man. Jon’s explanation is one of many children who have set their standard of being a real man or woman based on the strength and accomplishments of a superhero. Achieving victories that a superhero has demonstrated has caused many fans to feel as an accomplished being, finally worthy to be called a real woman or man. Superheroe s also tend to possess a perfect physique that enhances their powerful ability to conquer and defeat evil. They always have a defined figure, toned muscle in every area, and, usually, six-pack abs. Although physical image is more of an interest with teenagers and adults, this does have an effect on children, too.These role models that children are introduced to hold a nearly impossible figure for all children to achieve. It is from these images that communicate to kids that being overweight and lacking strength is unacceptable. This aspect is a contribution to children mistreating other children who do not hold to this idolized standard. My friend Jon stated, â€Å"I fell into the trap of mocking others, who were not perfect, when I was a kid. I also remember trying to hide any blemish of my own body, so that I would not become a victim of the scorn [from other children]†.Jon’s experience of feeling pressure to maintain a certain physical image exemplifies the cases of many superhero fans. Children are feeling pressure to portray a certain image in order to achieve self-security and acceptance from others instead of having a healthy mentality regarding food and exercise. Aside from all physical traits of a superhero, they also portray a strong sense of intelligence. It requires mass strategy and mental knowledge to defeat evil villains and their deceptive ways. Superheroes encounter many difficult and seemingly impossible challenges and manage to take them head on without any evidence of fear.Breann, a classmate in my English 101 class, stated, â€Å"I think that the intelligence of a superhero is extremely influential because they are faced against evil villains, who are known for their intelligence and strategic ways, and superheroes always end up defeating them†she continued, â€Å"When children see the knowledge of a superhero portrayed in their planning of defeat against their enemies and them achieve victory, it is a positive influ ence for the children to try their hardest in school to gain an education to be able to plan, have broad knowledge, and defeat, as well. Intelligence holds a large role in the world and one’s likelihood of reaching success. Intelligence is a positive attribute that superheroes portray when their knowledge and skill is shown through their preparation and process of defeating evil. A characteristic of all superheroes is their great achievement. Superheroes are constantly saving the world and others from harm.They have great impacts on the way most children that admired them grew up. Whether it was Batman, Wonder Woman, or some other supernatural being, they all had a lot to say about what it means to be a man or woman. Even if the ideals portrayed are imaginative beings, a superheroes image has the ability to influence any child. Works Cited Wall, Jon. Personal interview. February 22, 2013. Debarge, Breann. Personal Interview. February 22, 2013.

Investment and Market Risk Premium
Cost of Capital at Ameritrade Day 1 1. What factors should Ameritrade management consider when evaluating the proposed advertising program and technology upgrades? Why? -They should see how revenues have changed after adopting the new ad program and technology upgrades -They need to see ROI for their investments over time 2. How can the Capital Asset Pricing Model be used to estimate the cost of capital (required return) for calculating the net present value of a project's cash flows? it will help us determine the Cost of capital or discount rate which we can use to calculate NPV, in other terms the numerator will never change (FCF), only the denominator will based on the cost of capital3. What is the estimate of the risk-free rate that should be employed in calculating the cost of capiual for Ameritrade's proposed investment? – the risk free rate should be the T-bills rate or the average annualized total annual returns on US government securities = 3. %. In my opinion, we sho uld use the risk-free rate equal to yield of 20-year US government securities, because it is long-term capital investment. We may use 30-year rate, but we are investing in technology, and concerning the speed of technological enhancements, 20-year rate is optimal. So it is 6,69% 4. What is the estimate of the market risk premium that should be employed in calculating the cost of capital for Ameritrade's proposed investment? Market Risk PremiumThree distinct concepts are part of market risk premium: 1) Required market risk premium: the return of a portfolio over the risk-free rate (such as that of treasury bonds ) required by an investor; 2) Historical market risk premium: the historical differential return of the market over treasury bonds; and 3) Expected market risk premium: the expected differential return of the market over treasury bonds. Also called equity premium, market premium and risk premium.Market Risk Premium = Expected Return of the Market – Risk-Free Rate The e xpected return of the market can be based on the S;P 500, for example, while the risk-free rate is often based on the current returns of treasury bonds. First to find the Expected Return of the market, from Exhibit 6, We take the aggregate stock market and multiply by 12: = 15. 71% The Risk-free rate is 3. 8% =;gt; The market risk premium= 15. 7 – 3. 8 = 11. 9% (That is why we may use the difference between US Government Securities rate (6,69%)and historical Large Company Stocks annual returns.But we have 2 numbers: during1950-96 and 1929-96. The difference between them is 1,3%. I think that we should useâ€Å" younger†value of 14%, because the years 1930-1949, of course, were under market economy, but at the same time there were not so stable laws, a Second World War passed, many companies at that time worked for government orders, so this number may be a bit out of overall tendencies. ) 5. In principle, how would one go about determining beta for purposes of calcula ting the cost of capital for Ameritrade's proposed investment?TO calculate Beta for cost of capital, or asset beta: We need to find first the Equity Beta = by regressing stock returns over market returns and it will then be the slope. We also need to calculate the market value of the equity of the firm which is the price per share multiplied by the total number of shares outstanding (see attached notes) A cost of capital is a weighted average of the cost of debt and equity. Likewise, the asset beta is the weighted average betas of debt and equity. We use market value proportions of debt and equity (see CAPM, p. 476). Ba = (D/D+E)BetaD+ (E/D+E)BetaEIt is common to assume that debt has no relationship to market risk; that BetaD=0 Empirical studies of corporate debt returns suggest it would be better to assign some market-related risk to corporate debt; and use estimates ranging from 0. 20 to 0. 30. To get BetaE, the equity beta for Ameritrade, we would normally run a regression of equ ity returns on stock market returns. That is, we would estimate the slope of the line that best fits: Unfortunately, Ameritrade had their IPO (Initial Purchase Offer) in March of 1997, so there is not enough data at the time of the case to calculate a reliable beta estimate.So instead, we will look at comparable firms. Firms in the same industry pursuing the same types of projects will have the same sorts of risks, thus their asset betas will be approximately the same. The returns we calculate for these firms, based on stock price movement, dividends, and stock splits, are their equity betas. These are influenced by the degree of leverage each company is using (recall that higher leverage leads to higher ROE, EPS and DPS, but also leads to greater variability in earnings).Knowing the amount of debt in their capital structures (at market values), we can calculate the asset beta for each comparable firm. Then we will average these to use as a proxy for Ameritrade’s asset beta N ote: An agent that mediates sales and exchanges between securities buyers and sellers at even lower commission rates than those offered by a regular discount broker . As one might expect, deep discount brokers also provide fewer services to clients than standard brokers; such brokers typically provide little more than the fulfillment of stock and option trades, charging a flat fee for each.The problem that must be overcome in determining the implementation decision is the uncertainty of the cost of capital. Other Methods of Estimating Cost of Equity Capital: †¢The EP Method r = EPS / Stock Price †¢The Constant Growth (Gordon) Model r = DIV1 / P 0 + g compute g from earnings, dividend, or cash flow growth or use the sustainable growth estimate ? Equity Betas, the relationship of a given equity’s risk to that of the larger market, reflects two kinds of risk –The risk of the business itself –The risk that the debt a business has will prevent cash flow to equity ?We can de-lever these equity betas to strip out financial risk associated with leverage and find the implied beta for the business itself (asset beta) –Asset beta measures the business risk only and does not change with capital structure ? Often, the best way to estimate a forward looking asset beta for a company is to take a median of its industry peers asset betas (historically calculated) since one-time company events in the past will be averaged out ? We can then find the equity beta for the company by re-levering the industry asset beta to the target debt / cap ratio of the company ?Exhibit 4 provides various choices of comparable firms. Which firms do you recommend as the appropriate benchmarks for evaluating the risk of Ameritrade’s planned advertising and technology investments? Determine the betas for these firms. Let us agree that Charles Schwab is a comparable firm. Their price changes, dividends,and stock split information for 1992-1996 is in Exhibi t 5. If there were no stock split, thereturn, compared to the previous period, is given by: For example, if the price the previous period was $100, then wentup to $104, and in addition had a dividend of $8, the return would be +0. 12, or 12%.In ashort time period, the returns will be much closer to 0. If there is an X for y stock split, use the formula: Copy the Return values into Exhibit 6 alongside the appropriate dates, then regress theSchwab returns against the value-weighted NYSE returns for the same period. The slopeof the line is the equity beta. Do this for the other comparable firms. Calculate the asset betas using the formula inquestion 5 (twice, once with Beta D = 0 and once with 25. 0). Average the results. This should be a good estimate of Ameritrade’s asset beta. Finally, put these results back into the equation in #2 to estimate Ameritrade’s cost of capital

What to do when your boss is stealing your ideas
What to do when your boss is stealing your ideas There are lots of potentially difficult situations that arise in most workplaces- anything from annoying coworkers, to incompetent people on a project team, to having to work twice as hard in an effort to pick up the slack for a lazy, underperforming colleague who always seems to wiggle out of trouble. But the truth is, one of the most challenging professional situations to have to deal with is a scheming and self-serving boss who is constantly stealing your ideas or taking credit for your work, leaving you in the dust with nothing to show for your efforts and accomplishments. Hopefully this doesn’t sound familiar or hit too close to home for you- but if it does, we know how difficult it can be. The last thing any of us want to do is put ourselves into an adversarial situation with our bosses, so there’s a real impulse not to say or do anything about it- which can quietly â€Å"signal†your boss that you’re okay with their bad behavior or at the very least not going to rock the boat for them, which means the theft may continue (or get worse).It’s important to do something when your boss is stealing your ideas. But how can you handle the situation delicately enough so that you don’t make things unbearable for yourself, yet firmly and decisively enough to send a clear message that you’re not willing to put up with this?If you or someone you know is struggling with this reality, there is hope, and a way forward. Entrepreneur published an article that highlights strategies for dealing with a boss who takes credit for your ideas. Use the following to help guide you through the potential hazards and pitfalls of the tough spot you’re in and hopefully make it through unscathed.Step 1: Evaluate the situationWhen you first start getting the feeling that your boss is taking credit for your ideas, your first step is not to unleash the fury on the powers that be in an effort at vengeance or retribution. Take a step back to get some valuable perspective and evaluate the situation. Is your boss really stealing your ideas or just aggregating and presenting the work for the team that reports to her or him? Are you absolutely certain that you’re not getting credit for your work? Just because you may not receive instant adulation for your ideas does not mean that your efforts are going unnoticed. Perhaps your boss is not the overly effusive sort, but nonetheless is appreciative of your contributions and is giving credit where it’s due in a subtle way, or is simply waiting for your next review period to give you your well-deserved rewards? Bottom line- make sure you know for sure that your boss is stealing your ideas before taking things any further.Step 2: Get a second opinion/witness.Okay, so you’re fairly certain that your boss is indeed taking credit for your work- what should you do next? The next best step is to get a second opinion in an effort to have a witness to t he situation in your corner. Why is this so important? Because without a witness, unless you have absolutely irrefutable evidence it’s basically your word vs. your boss’s, and in this scenario the boss often wins. Don’t put yourself in that scenario- instead, choose a credible and reliable witness, preferably someone with a little clout at your workplace, and help your case by having that person in your corner. It could make all the difference if you decide to take things further.Step 3: Document your case.A strong, impassioned story and credible witness will go a long way towards supporting your claim of idea theft, but nothing beats a solid â€Å"paper trail.†Wherever feasible, have some ironclad evidence that documents the onerous events- everything from emails to recorded instances of theft and proof that the ideas were indeed yours to begin with will all serve to substantiate your claim. Nothing is more disheartening than making a bold claim of thef t that you’re unable to prove and it ultimately goes nowhere. Not only will your work situation not improve, it will likely become even more uncomfortable for you there.Step 4: Communicate with your boss.No, we’re not suggesting you kick open their office door and yell at them at the top of your lungs in an effort to get them to admit their wrongdoing. Instead, we’re saying that there may be a more peaceful and professional way to reach a satisfying conclusion. If you politely discuss the situation with your boss, they may be able to capably explain why you’re mistaken about what has transpired. Or maybe they’ll realize they’ve failed to properly give you the credit you’re due are willing to make amends. Often, the path of least resistance is the best one to take first. Hopefully your boss is reasonable enough to deal with, provided your approach is free from hostility and you’re open to reasonable and equitable compromise.If y ou think your boss might be profiting from your ideas without sharing the credit, don’t just do nothing- but don’t do anything rash, either. Take a breath, assess the situation, and make your way through the measured and professional steps mentioned here to come to a resolution that gives you the credit you deserve.

How Weather Affects Fall Colors
How Weather Affects Fall Colors Nothing says autumn quite like a lazy drive through the countryside with the sun illuminating oranges, reds, and yellows in the treetops. But before planning a day of leaf-peeping, its a good idea to check local and regional weather forecasts- and not simply for travel weather purposes. Weather conditions such as temperature, precipitation, and amount of sunlight, actually determine how vibrant (or not) fall colors will be. Leaf Pigment Leaves have a functional purpose for trees: They produce energy for the entire plant. Their broad shape makes them good for capturing sunlight. Once absorbed, the sunlight interacts with carbon dioxide and water within the leaf to produce sugars and oxygen in a process known as photosynthesis. The plant molecule responsible for this process is called chlorophyll. Chlorophyll is responsible for giving a leaf its trademark green color. But chlorophyll isnt the only pigment residing within leaves. Yellow and orange pigments (xanthophylls and carotenoids) are also present; these remain hidden for most of the year because chlorophyll masks them. Chlorophyll is continually depleted by sunlight and is replenished by the leaf through the growing season. Only when chlorophyll levels subside do the other pigments become visible. Why Leaves Change Color While a number of factors (including weather) influence the brilliance of leaf color, only one event is responsible for triggering the decline of chlorophyll: the shorter daylight and longer overnight hours associated with the change in season from summer to fall. Plants depend on light for energy, but the amount they get changes through the seasons. Beginning on the summer solstice, Earths daylight hours gradually decrease and its nighttime hours gradually increase. This trend continues until the shortest day and longest night is reached on December 21 or 22 each year (the winter solstice). As the nights progressively lengthen and cool, a trees cells begin the process of sealing off its leaves in preparation for winter. During winter, temperatures are too cold, sunlight too dim, and water too scarce and susceptible to freezing to support growth. A corky barrier is formed between each branch and each leaf stem. This cellular membrane blocks the flow of nutrients into the leaf, which also stops the leaf from making new chlorophyll. Chlorophyll production slows and eventually stops. The old chlorophyll begins to decompose, and when its all gone, the leafs green color lifts. In the absence of chlorophyll, the leafs yellow and orange hues dominate. As sugars become trapped inside the leaf by the trees sealant, red and purple (anthocyanins) pigments are also created. Whether by decomposition or by freezing, all of these pigments eventually break down. After this happens, only browns (tannins) are left. Effects of Weather According to the U.S. National Arboretum, heres how the following weather conditions at each stage of the leaf growing season work to the benefit or detriment of foliage come September, October, and November: During spring, a wet growing season is ideal. Drought conditions during the spring (the beginning of the leaf growing season) can cause the sealing barrier between leaf stem and tree branch to form earlier than normal. This, in turn, can lead to an early shutdown of leaves: Theyll drop before theyve had a chance to develop fall coloration.From summer into early autumn, sunny days and cool nights are desirable. While adequate moisture is good during the early growing season, it works to mute colors in the early fall. Cool temperatures and abundant sunshine cause chlorophyll to be destroyed more rapidly (recall that chlorophyll breaks down with exposure to light), thus allowing yellows and oranges to be revealed sooner, and also promoting the formation of more anthocyanins. While cool is best, too cold is detrimental. Freezing temperatures and frosts can kill thin and fragile leaves.During autumn, calm days prolong viewing opportunities. Once the autumn season arrives, l eaves need time for the buildup of chlorophyll to entirely fade and their dormant pigments to fully take over. Gusty winds and hard rains can cause leaves to fall before their full color potential is reached. The conditions that make for spectacular autumn color displays are a moist growing season followed by a dry autumn with warm, sunny days and cool (but not freezing) nights.

Data analysis - Speech or Presentation Example Teachers report using many of the reform strands almost every day or several times a week. The reforms most used (by at least 70% of the teachers) were constructivism, learning styles, thematic approach, alternative assessment, equity, STS, technology, and science subject matter. Alternative assessment (90%), equity (88%), and technology (83%) were the most used reform strands the teachers reporting using it â€Å"almost every day†or â€Å"several times a week†. Classroom management stood out among the reform strands least implemented in the classroom. Only 45% of teachers reported using classroom management almost every day or several times a week. Less frequently used reform strands (used once a week, less than once a week, or never) by over 30% of teachers include classroom management (55%), cooperative learning (42%), hands-on/minds-on activities (37%), and nature of science (30%). Considering all items measuring the necessity of the reforms to be an effective science teacher are equal, a new variable â€Å"belief†was formed. Similarly, a new variable â€Å"implementation†was formed by adding all items in implementation of the reform in teacher
