AP ENVIRONMENTAL SCIENCE 2014-2015

Personal Philosophy:

“You cannot teach a man anything; you can only help him find it within himself.”

Galileo Galilei

Galileo is one of my heroes. He had a natural curiosity and an intense desire to understand the world around him. He was a brilliant observer and experimentalist when science was thought of as an exercise of the mind. He was not satisfied to accept theories without evidence. I desire to emulate Galileo. My goals as a teacher are to foster the natural curiosity of my students, to sharpen their powers of observation, to cause them to question accepted theories, to stress the importance of evidence, and to develop their problem solving skills. As a teacher of environmental science, I feel an extra responsibility to help my students understand their role as citizens and stewards of the earth. Our students, in a few years, will be the ones making decisions about how we use earth’s precious natural resources, about how we deal with the challenges of climate change, and about how we can potentially use new technologies to help. I want to make sure they have a strong background so they can make informed decisions. School Profile: The school is a public high school of nearly 1800 students serving grades nine through twelve. It is located about 70 miles north and east of New York City. The town is a rural/suburban town with farms, subdivisions of large houses, and a historic downtown area.

AP ES FINAL PROJECT

Put together a portfolio that summarizes your experience throughout the year in APES. The portfolio must consist of 10 images (not 9 or 11). You must include among your images at least (1) one map, (2) one diagram, (3) one photograph. The other seven images can be any combination. No more than two images may be from any particular unit, fieldtrip, lab activity, reading, anything…. The images may be your own work (i.e. a drawing of a lab set-up, a graph you made, or a picture you took) or copied from somewhere (properly cite your sources). After you identify your 10 images: 1. write an explanation for each image. The explanation must include the science behind the image in your OWN words. Should be at least one paragraph long. NO “copy-paste”. 2. Answer the question, "Of all the images you've looked at this year in APES, why is this particular one important to you?" 3. Please include a title page and a works cited page. Your portfolio may be a printed or written hardcopy… or it may be submitted electronically to me as a power point or word document. Each image/explanation is worth 10 points…. For a total of 100 points.

• 2 points for choice of image - unique, interesting, relevant • 4 points for scientific explanation of image – demonstrates depth of knowledge in your own words • 3 points for why it is important to you – meaningful answer given, can be personal, please avoid

answers like – it is interesting… tell WHY it is interesting to you. • 1 point for citation of source of image and/or scientific information.

Critical Evaluation of Environmental News Procedure Find a published report that discusses a controversial environmental issue (not a short article)

A. Summarize information contained in the article/report using the guidelines below B. Evaluate the article/report based on the criteria below.

A. Summary Guidelines 1. MLA citation of the article/report 2. A one or two sentence thesis statement on what the main idea of the article/report is about 3. A summary of some of the important information discussed in the article/report. Some details and examples. B. Evaluation guideline questions – please give detailed and specific answers and/or examples 1. Different media carry with them different degrees of credibility. A scientific journal article, for example, is likely to be more credible than a newspaper report, which in turn is likely to have higher credibility than a tabloid article. In what type of publication does your report appear? 2. Is the author of the report given? Who is it? Is it an "individual" or an "organization"? If an organization has produced the report, determine the mission of the organization. If an individual has produced the report, what credentials or affiliations does he/she have? 3. Does the report attempt to persuade, advocate or inform? Explain 4. What information was used to prepare the report? Some possibilities include (but are not limited to) :

• observation of actual occurrences • consultation with experts • discussion with non-experts • reports in scientific journals • reports or findings from a particular organization (scientific or other) • sources are not stated in article

5. Is this information properly referenced so that you could check it out if you wanted to? Explain 6. What is the date of publication? Is the information in the report (or the report itself) up-to-date? How important is the date of publication for this particular topic? 7. Is there a basis for suspecting bias on the part of the sources, the author of the report, or yourself? If so, state which of the following bases you detect from the list of common biases below: • the author or source has a clear stake in the issue and will benefit in some way from the claims that are

being made • only selected information is being reported (Are you aware of other information that would refute the

claims being made?) • you reject the claims of the article because you disagree with them or you accept them because the claim

happens to agree with your opinion • the publication has a well-known or suspected position on the issue For each of the biases you have detected, explain where in the article it appears.

Page 9: AP ENVIRONMENTAL SCIENCE - Newtown Public · PDF fileAP ENVIRONMENTAL SCIENCE . ... The Curriculum is based on the national curriculum set by the AP College Board See the website below

8. Claims are positions or conclusions that are stated in the article. They should be supported by some kind of evidence - specific observations or data that are used to support a given claim. For example, the claim that a fish kill was caused by a spill of sulfuric acid into a river might be supported by the following evidence:

• an accident involving a tanker truck containing 1000 gallons of sulfuric acid occurred upstream of the fish kill • 500 dead fish were counted downstream from the accident site by a fisheries biologist the day after the accident • no dead fish were found upstream of the accident • water samples taken downstream from the accident by the biologist indicated a pHmeasurement of 4.0 • previous studies have found that pH measurements of less than 4.5 are toxic to most fish

List two specific claims and the specific evidence supporting them. 9. Do the claims in the report follow logically from the evidence given or are "leaps in logic" required to reach the same conclusions as the authors? Could alternative claims be made from the same evidence? 10. Is there anything in the article that you consider to be "unnecessarily sensationalized" to make a point or to stimulate some emotion? Examples may include misleading or exaggerated titles, phrases that are meant to appeal to our emotions or accompanying photographs. Descriptor Awesome = +3 Good = 42 Not Bad = 2 Needs Work = 1 Choice of article (can be +2 only)

Interesting, current, and relevant article

Interesting and/or relevant and/or current article

Measuring Species Diversity in a forest Using Shannon Weiner Diversity Index

Background: Biodiversity is the population heterogeneity of a community, or the number of species in the area. Maintaining biodiversity is important for a variety of reasons.

• New medicines have been discovered by screening diverse ecosystems. • Genetic diversity in crop plants and their wild relatives provides breeders with the “raw material”

needed to select for traits in response to new agricultural challenges. • Diverse communities are generally less susceptible to perturbation than similar but less diverse

communities. • Biodiversity provides an aesthetic value that humans find appealing.

When pollution is present or a human disturbance has occurred in a community, biodiversity is typically lower than in an undisturbed community.

Diversity indices are typically used to measure and compare species diversity in nature. Comparisons may be important

to assess the impacts of human development or pollution. For example, when human disturbance occurs in an ecological community, diversity is typically low. There are several measurements that are used to quantify diversity:

Species Richness is a count of the total number of different species in the area under study.

Species Evenness is a measure of the relative abundance of species in the area (how individuals are distributed throughout the species). Species Dominance in its simplest form is the most abundant species.

Communities with large number of species with individuals more evenly distributed among those species are the most diverse while communities with few species with individuals making up mostly one of those species are least diverse.

There are several species diversity indices (mathematical equations) used by environmental scientists and ecologists. Any one index will not provide an adequate assessment of diversity. Species diversity should be expressed as a combination of multiple indices.

Purpose: For some ecological investigations, it may be useful to measure diversity of one taxonomic group. For example, if a plant ecologist were interested in studying species of trees, they would measure tree diversity and exclude other kinds of plants and organisms. For this lab, we are concerned with the biodiversity of trees in the forest surrounding NHS. We will measure species richness, evenness, dominance, and the Shannon Diversity Index of the forests and compare it to another habitats. The calculations will be done for our data and for a fictional forest The Shannon Weiner Index

The Shannon Weiner diversity index (H) is an index that is commonly used to characterize species diversity in a community. The Shannon-Weiner index was developed from information theory and is based on measuring uncertainty. The degree of uncertainty of predicting the species of a random sample is related to the diversity of a community. If a community is dominated by one species (low diversity), the uncertainty of prediction is low; a randomly-sampled species is most likely going to be the dominant species. However, if diversity is high, uncertainty is high.

S-W index accounts for both abundance and evenness of the species present. The proportion of species i relative to the total number of species (pi) is calculated, and then multiplied by the natural logarithm of this proportion (lnpi). The resulting product is summed across species, and multiplied by -1:

∑=

−=S

iii ppH

1ln Equation 1

Page 12: AP ENVIRONMENTAL SCIENCE - Newtown Public · PDF fileAP ENVIRONMENTAL SCIENCE . ... The Curriculum is based on the national curriculum set by the AP College Board See the website below

Where pi = the proportion of individuals of species i and H is the S-W index. Notice that there is a negative sign in front of the summation sign. Equation 1 can be rearranged to produce a second (easier) equation

H’ = N ln N - (ni ln ni) ________________

N Equation 2

Where ni = number of individuals of a species and N is the total number of individuals in the community. Equations 1 and 2 are equivalent; you can use either one.

Given a large sample with many species, the Shannon-Weiner Index (H) will vary from 0 to 4.6. A value near zero means that the individuals are all from the same species. A value near 4.6 means that the individuals are evenly distributed among the species.

S-W equitability (EH) (or evenness) can be calculated by dividing H by Hmax (here Hmax = lnS). Equitability assumes a value between 0 and 1 with 1 being complete evenness.

Warning, no single index offers “the best” measure of diversity: they are chosen on their suitability to different situations. It can be difficult to evaluate objectively without reference to other ecosystems.

Procedure: 1. Set up a 10m x 10 m quadrat – break the quadrat up into 4 sections. Each group will be responsible for

the data for their section. 2. Count the number of trees in the each section – add to get the number in this plot. Record as N for total

number of trees in this 100 m2 plot. 3. ID all the trees in your section. Work as a group - mark the tree as you identify it so it is not counted

twice. 4. Count the number of each species and record. We will combine the data in class. The total number of

different species, Species Richness, (or Tree makes) in each plot = S 5. Get a sample of a leaf from each species. When we get to the class, we will press them. 6. Using a data sheet for your section of the quadrat, count (tally) the number of individuals of different

species of trees ( ni) in your section. The index letter “i” simply runs from 1 to S, tracking each species of tree. Share data with other members of the class so that you have data for all four sections and therefore, the whole plot.

7. In your class data table, calculate the relative abundance (pi) for each tree species in the quadrat to three

decimal places. This is the proportion of the community represented by each species i.

pi = ni/N

ni = number of individuals in species i (i.e., the number of each type of tree) N = total number of individuals in all species (all trees sampled)

8. Calculate the Shannon Diversity Index (H’, read as “H prime”) to three decimal places.

H’ = - Σ [pi⋅ln(pi)] Perform the summation (Σ) for i=1 to S using the attached sheet. Note the negative sign in front of the summation. This ensures the index will be positive. A greater H’ indicates higher diversity. Do the same for the Fictional Forest.

9. Complete the Diversity Measurement table for the quadrat. a. For Species Richness, use S b. Compare Species Evenness for the plot and for the Fictional Forest. between both quadrats. For

Dominance, indicate the dominant species for each quadrat. c. Insert the Shannon Diversity Index (H’)

10. Complete Discussion/Conclusions section. Ensure your comments are clear and easy to read (i.e.,

organized). This section must be completed on a separate sheet, preferably typed.

Name:____________________________________Class:____________________Date:______________ Purpose: To demonstrate the effects of thermal and chemical pollution on aquatic animal life. For these activities, you will use a culture of yeast with milk as a food supply. The yeast used in these experiments represents any cold-blooded form of animal life that lives in water. (unicellular or multicellular animals such as paramecium, macro invertebrates, fish, crawfish, frogs, worms etc…) The methylene blue is a dye that indicates the presence of oxygen. When oxygen is present, the dye remains blue. As oxygen is depleted, the dye loses its color. Part A: The Normal Environment. For this part of the experiment, you will need: a plastic cup, the milk solution, a plastic culture tube, a pipette, the yeast suspension, a thermometer, a hot plate, and methylene blue.

• Warm some water to about 35 deg C. • Put some yeast into one of the plastic cups and put milk (100 ml) into a second plastic cup. • Pour the milk into the plastic tube until it is about ½ full. • Add 20 drops of the yeast suspension • Add 15 drops of the methylene blue. • Cap the tube and gently shake. Place the tube into the warm water. • Record your initial observations (color, presence of bubbling): • Place the tube in the warm water for about 5 – 10 minutes. Record your observations

Time Bubbling Color Other

Initial

3 minutes

5 – 10 minutes

1. What is the cause of the bubbling? 2. Why did the color change? What has the yeast done to the oxygen? 3. In order to survive, animals need oxygen. Aquatic animals get their oxygen from oxygen gas dissolved in the water ( D.O.). How does oxygen get dissolved in the water?

Page 26: AP ENVIRONMENTAL SCIENCE - Newtown Public · PDF fileAP ENVIRONMENTAL SCIENCE . ... The Curriculum is based on the national curriculum set by the AP College Board See the website below

• Seal the plastic tube and shake it again. This simulates the action of waterfalls, waves, or riffles.

4. What happens to the color? What does this tell us about the oxygen?

• Let the tube sit in the warm water for another 5 minutes. 5. What happens? Part B: Effects of Temperature Aquatic organisms are sensitive to temperature. Most organisms have a narrow range of temperature in which they can exist and cannot survive changes of more than a few degrees in the water temperature. You will need: yeast, milk, 3 tubes, pipettes, 3 styrofoam cups, ice, hot plates, methylene blue.

• Prepare three water baths of different temperatures: 15 deg C; 35 deg C; 55 deg C • When the water baths are set, fill three plastic culture tubes ½ full with milk. Add 20 drops of the yeast

suspension, and 15 drops of the methylene blue to each tube. • Gently shake each tube and place into the three different baths. • Observe (color and bubbling and rate at which color changes

Temp deg C Initial observations After 10 minutes

6.What do you conclude from your results? 7. What do you conclude about the rate at which organisms use oxygen at different temperatures?

• Clean out the tubes. Fill one tube with the cold water and one with the hot water and 15 drops of methylene blue. Observe the color.

Page 27: AP ENVIRONMENTAL SCIENCE - Newtown Public · PDF fileAP ENVIRONMENTAL SCIENCE . ... The Curriculum is based on the national curriculum set by the AP College Board See the website below

8. What can you conclude about how temperature affects the amount of dissolved oxygen water can hold.

Gases dissolve in water as it flows down streams, over rocks and waterfalls, and as the wind causes waves. At low temperatures, larger amounts of gases, such as oxygen, will dissolve. Picture a pot of water about to boil. Some of the bubbles around the bottom of the pot ( and your culture tube) are gases that are coming out of the water because of high temperatures. 9. Make a statement concerning the effects of temperature on life in the water. Part C: Chemical Contamination Man dumps many materials into the water that normally are not found there. Many different types of chemicals produced by man are harmful to other organisms. Various poisons are released into waters by factories, mines, and other businesses. These chemicals can, like temperature, pollute directly or indirectly. Direct pollution can kill organisms directly. One material that can end up in the water is lead. Lead is a heavy metal used in paint and metal factories. It is a neurotoxin for humans. We will use a solution of lead nitrate for this experiment. 1. Get 2 culture tubes and be sure that they are clean. Fill both tubes about ½ way with milk. Add 20 drops of yeast suspension and 15 drops of methylene blue to each test tube. Add 10 drops of lead nitrate to one of the tubes. Cover the tubes and shake well. Observe the tubes for several minutes and record your observations here. 2. What do you conclude about the effects of the lead on the use of oxygen by the yeast. Lead inactivates enzymes which yeast need to break down food. If the yeast can’t break down the food, then it won’t use oxygen.

Another way in which a chemical can pollute the environment is by upsetting the balance of the number of organisms. Chemicals that make one animal grow in numbers more than usual are indirect pollutants. This prospering organism may use up nutrients that other organisms need to live. Animals produce waste products. The animal’s wastes will be more than the environment can handle. They change the makeup of the water so that the original animals can no longer live there. Cultural Eutrophication: Fertilizers are another type of pollutants. Fertilizers typically contain different amounts of nitrates, phosphates, and potassium. These nutrients stimulate the growth of algae. Algae is a green plant and produces both food and oxygen. Algae grows on the surface of water. Remember how the milk and yeast with the indicator in part A only remained blue on the surface. This is also how ponds and other still water get oxygen, from the surface. If too much algae grown on the surface, it blocks off all the area in contact with oxygen and can suffocate the pond. Excess algae can also lead to hypoxia. As algae dies, it sinks to the bottom. During the decay process, bacteria use up oxygen in the water causing oxygen depletion. Extension questions: Answer on a separate piece of paper.

1. Summarize the effects of heat on living things.

2. Streams and rivers have been widened and slowed by dams. How would this slowing of water affect the amount of Oxygen present in the water? Explain. What effect would this have on the organisms that live in the water?

3. As the cost of electricity gets higher and fossil fuels get rarer, many areas may turn to nuclear power to generate electricity. One of the drawbacks to nuclear power is the very large amount of heat given off by the nuclear reactors. Surface water is often drawn into a nuclear reactor to use as a coolant. If a nuclear power plant were to be built near you, what would you suggest to the builders?

4. What are some ways that pollution can be reduced in the waterways near you?

Your Ecological Footprint

1. Go to the following website, read about what an ecological footprint is and do your footprint: http://www.footprintnetwork.org/gfn_sub.php?content=footprint_overview . Use your footprint to fill in the top part of the table on the next page. THEN, Decide on some changes you can make to reduce your footprint and redo your footprint. Use this information to help you decide on positive changes you commit to this year to reduce your footprint. 2. Compare your footprint to the USA and the world and finish the table on the next page: http://www.footprintnetwork.org/gfn_sub.php?content=footprint_acres 3. Visit http://chartsbin.com/project/our_planet_in_ecological_debt.html for some good info 4. Answer the questions. World Footprint: Do we fit on the planet? Today humanity uses the equivalent of 1.5 planets to provide the resources we use and absorb our waste. This means it now takes the Earth one year and six months to regenerate what we use in a year. Moderate UN (United Nations) scenarios suggest that if current population and consumption trends continue, by the 2030s, we will need the equivalent of two Earths to support us. And of course, we only have one. Turning resources into waste faster than waste can be turned back into resources puts us in global ecological overshoot, depleting the very resources on which human life and biodiversity depend. The result is collapsing fisheries, diminishing forest cover, depletion of fresh water systems, and the build up of carbon dioxide emissions. These are just a few of the most noticeable effects of overshoot. Overshoot also contributes to resource conflicts and wars, mass migrations, famine, disease and other human health related issues. So what will it take for humanity to live within the means of one planet? Individuals and institutions worldwide must begin to recognize ecological limits. We must begin to make ecological limits central to our decision-making and use human ingenuity to find new ways to live, within the Earth’s bounds. This means investing in technology and infrastructure that will allow us to operate in a resource-constrained world. It means taking individual action, and creating the public demand for businesses and policy makers to participate. Using tools like the Ecological Footprint to manage our ecological assets is essential for humanity’s success. Knowing how much nature we have, how much we use, and who uses what is the first step, and will allow us to track our progress as we work toward our goal of sustainable, one-planet living.
