Knowledge-based: Experiment-based: Though the test is mostly conceptual, you may be quizzed on knowledge as well: What is an example of commensalism? How does carbon go from the air back into living things? Etc. You should bring a ruler (though any straight edge will do). You should not bring a calculator or liquid paper.
 * <span style="color: #0100ff; font-family: Arial,Helvetica,sans-serif; font-size: 16px;">Dec. 11th: **<span style="font-family: Arial,Helvetica,sans-serif; font-size: 16px;">List of topics for the exam! (Sorry this was so late to be posted)
 * Types of growth - Linear vs. Exponential
 * Limiting factors in an environment (resources, space, environmental conditions)
 * Carrying capacity
 * Birth rate, death rate, immigration, emigration
 * Adaptation and "fitness" (how good an individual is at surviving and reproducing)
 * Levels of biological organization: (Atom -> Molecule -> Cell -> Tissue -> Organ -> Organ System ->) Organism -> Population -> Community -> Ecosystem -> Biome -> Biosphere
 * Biotic and abiotic factors
 * Commuity interactions: Symbiosis, Mutualism, Commensalism, Neturalism, Parasitism, Predation, Competition
 * Explaining changes in a population
 * Cycling of organic compounds: carbon cycle, nitrogen cycle
 * Types of variables
 * Graphing: Selecting the type of chart, choosing an appropriate scale, presenting more than one thing on the same graph (E.g. P. aurelia and P. caudatum populations), drawing a trend line
 * Conclusion: Re-state results, explain results, evaluate hypothesis
 * Evaluation: Explain why the method was chosen, identify problems in the experiment, suggest improvements to the experiment

Check out [|this video] for a very simple view of: **Yeast + sugar** **<span style="font-family: Arial,Helvetica,sans-serif; font-size: 16px;">→ CO <span style="font-family: Arial,Helvetica,sans-serif; font-size: 16px; vertical-align: sub;">2 **<span style="font-family: Arial,Helvetica,sans-serif; font-size: 16px;"> **+ ethanol**. Here is [|a video of a teacher doing a similar lab], but unlike us, he is using balloons to see the gas. We, however, will be doing something even more advanced: measuring the volume of the gas. For this, we will use something called a eudiometer. Here is [|a video of the set-up we will be using] (in the video they are using a chemical reaction to produce gas, but we will use yeast).
