15. Terminology (cont.) Free Response Strategies These phrases do not require complete sentences: A calculator may not be used on any part of the Environmental Science Test. Calculate Draw and label Graph the data List… Plot these data Show calculations to support your answer Show the setup for the calculations

16. Example FRQs 1.Describe a connection between the weather change associated with a hurricane and the transmission of diseases. (On this type of question, use the words increase/decrease). Example:

17. Example FRQs (cont.) 2.Describe an important environmental (economical) problem associated with a hurricane. (Here again, you can use the words increase/decrease). A(n) _____ in water temperature causes habitat destruction resulting in a _______ of biodiversity. Any time there is a problem in the question, you will need to give: the problem (habitat destruction) cause of the problem (_________ temperature) and the effect (________ biodiversity).

18. Example FRQs (cont.) 3.Describe a strategy to control ticks. (A strategy usually requires at least two methods. A third method may give you an elaboration point.) Ex. One method that can control ticks is to ____________. A second method that can control ticks is to ___________.

19. Example FRQs (cont.) 4.Identify and describe one way humans have degraded wetlands. (You are asked to do two things.) Ex. ______ ________ (identified) are one way humans have degraded wetlands. By ___________________________________ humans have caused habitat destruction (description). In order to get the point, both the identification and the description must be there.

20. Example FRQs (cont.) 5.Discuss one role that kelp forests play that is ecologically (economically) important. (This prompt requires two sentences, one for the role and the second for the discussion). Only the first role you list will be graded. Ex.

Answer: One incentive that a government could offer its citizens that would favor a reduction in the growth would be a…

25. Example FRQs (cont.) 10.Identify and describe one abiotic water test. (You are asked to do two things. Two sentences may be necessary) Example:

27. Designing an Experiment the APES Way Here is a guide to help you accumulate the most points from this type of question. 1.State a hypothesis. It must be a clear statement of a hypothesis. You must identify it as a hypothesis: “My hypothesis is...” Also, use an if/then statement. Such terms as: increase/decrease are important in your hypothesis. I would wait to formulate your hypothesis because as you create your experiment things may change. Keep it simple. 2.Specify a control. My control is...

28. Designing an Experiment (cont.) 3.Identify and hold constant one experimental factor. My experimental factor is … 4.Describe what is being measured. 5.Explain how the data is collected. Somewhere here is a good place to write your hypothesis. 6.Identify your independent and dependent variable. Drawing a graph to show what will happen is a nice addition, however, don’t spend a lot of time here.

29. Designing an Experiment (cont.) 7.Must include two of the following: A.A time line for the experiment. Ex. 24 hour period/ 2 growing seasons B.Materials used (Provide a list) C.Correlation to other experiments. D.Specific sample size. Ex. Eight 2 ounce bottles. Two 10 gallon aquariums. E.Specify size of area where the experiment is taking place. 8 ft./8 ft. square.

30. Designing an Experiment (cont.) 8.Must include one of the following: (This will give you an elaboration point) A.Repeated experiments. I will repeat my experiment 2 more times to show validity. B.How other variables are controlled or tested. C.Correlation to other experiments. D.How the experiment could be expanded or modified. E.Relate to/discuss additional research. 9.Give expected results.

31. Environmental Laws Important Environmental Laws and what they do: A.Endangered Species Act – Protects the habitat of threatened and endangered species.

C.CITES Treaty – (Convention in International Trade of Endangered Species) It regulates international trade of protected species and their products. D.Clean Water Act – Protects wetlands. Prevents habitat destruction. Regulates the discharge of pollutants in U.S. waterways. E.Clean Air Act – Establishes ambient air standards for four primary pollutants.
