AARRGGGHHHHH! The exam ………
90 Minutes 4 questions 90 Minutes 100 questions
C Multiple Choice B 100 multiple-choice questions (1.5 hours) Designed to cover the breadth of the students’ knowledge and understanding of environmental science . Thought-provoking problems and questions based on fundamental ideas from environmental science are included along with questions based on the recall of basic facts and major concepts The number of multiple-choice questions taken from each major topic area is reflected in the percentage of the course as designated in the topic outline A E D
Multiple Choice- General Ideas • Do not leave an answer blank! They have changed the rules now. So there is no benefit to leaving it blank. Guess if you have to. • Be careful of the wording. Underline keywords like: • all of the following EXCEPT • Increases / decreases • is most likely • Go with your first instinct. Do not overthink the question. • Pay attention to the time.
Multiple Choice- Types of questions • Cluster • This will be about 25% of the MC questions • Given a visual with A-E on it • Four or Five questions relate to the visual • Since you have the same information for 4-5 questions, these take the least time to answer.
Multiple Choice- Types of questions • Data • This will be about 25% of the MC questions • Data given as graph or table • graphs look for slopes (rates) or points (data) • tables look for changes in trends • Two or Three questions asked • Since you have the same information for 4-5 questions, these take the 2nd least time to answer.
Multiple Choice- Types of questions • Stand Alone questions • This will be about 50% of the MC questions you get • Mixed easy/medium/hard- there is no trend • One does not lead to another • These take the most time to answer since all information given is just for one specific question.
Free Response emphasizes the application of principles in greater depth students must organize answers to broad questions, thereby demonstrating reasoning and analytical skills, as well as the ability to synthesize material from several sources into cogent and coherent essays .
Free Response- Tips • Before answering any questions Read the question twice. Read the question twice. • Underline (highlight, outline, etc.) what the question is asking for • Answer the question(s) asked and only those questions. • Answer all parts of the question. • Begin answering the question in the order it is written.
Free Response- Tips Each is a decade
Free Response- Tips Answer the question parts in the order called for and label them "a", "b", "c", etc. as they are labeled in the question. It is best not to skip around within the question. However, the four essays do not have to be answered in any particular order. Write clearly and neatly. It is foolhardy to antagonize or confuse the reader with lousy penmanship. Readers thoroughly appreciate legible handwriting. Use a ballpoint pen with blue or black ink. Bring an extra, just in case. Go into detail that is on the subject and to the point. Be sure to include the obvious (for example, "light is necessary for photosynthesis"). Answer the question thoroughly.
Free Response- Don’ts Don't panic or get angry because you are unfamiliar with the question. You probably have read or heard something about the subject - be calm and think. X
Free Response- Don’ts Don’t waste time on background information or a long introduction unless the questions call for historical development or historical significance. Just get to answering the question. Don't ramble. Get to the point. Say what you know and go on to the next question. You can always come back later and add information if you remember something. “The Greenhouse Effect is this effect where things tend to get hotter than they should like air in a greenhouse. It starts with light from the sun coming in. It’s UV light mostly. While some gets absorbed by ozone in the stratosphere some makes it to the surface and gets absorbed there. The ozone layer is thinner now, but it will return by 2050 thanks to the Montreal Protocol. The surface of Earth re-emits the absorbed light as IR. That’s infra-red. This light can be absorbed by small molecules in the air like CO2, CH4, H2O, O3 (but in the troposphere, not the stratosphere), and CFC’s. They redirect the IR back to the atmosphere instead of it escaping and it heats the air. Hotter air means a hotter Earth … Sources of greenhouse gases are industry, burning fossil fuels for power production, cows burping (really!), and transportation. The Greenhouse Effect is a process where some of the UV light from the sun is absorbed by the surface of the earth and re-emitted as infra-red. This lower frequency light is absorbed re-radiated by small molecules in the atmosphere, mainly CO2. This heats the lower atmosphere higher than if the gases were not present. The amount of CO2 in our atmosphere has increased a great deal from human industry and fossil fuel combustion. This has made the greenhouse effect even greater and increased global temperatures.
Free Response- Don’ts Don't use felt tip pens - they leak through the paper and make both sides hard to read. Do not obliterate information you want to delete. One or two lines drawn through the word(s) should be sufficient. Don't write sloppily. It is easier for the grader to miss an important word when he/she cannot read your handwriting. Don't write more than a very few words in the margin.
