1. Review Stations Ms. Klinkhachorn November 8, 2010 Biology

2. Directions Read the scenario Identify the IV and the DV Identify at least 2 controlled variables Make a graph or a table that would be appropriate for the scenario

3. Scenario 1 Jay is curious about how fertilizer affects the height of plants. He designs an experiment that uses three different amounts of the same brand of fertilizer on the same kind of plant. He uses 10 grams, 20 grams, and 50 grams of fertilizer with the plants and records the plant height every 3 days for 30 days.

4. Scenario 2 Plants need light in order to grow. A gardener conducts an experiment with his tomato plants using different colors of light to see if there is any effect. He plants three beds of plants under different lighting conditions. One bed is exposed to sunlight, while the other two are exposed to green light and blue light, respectively. He waters them each day at the same time with an equal amount of water. At the end of two weeks, he uses a ruler to measure the height of the plants.

5. Scenario 3 Mike discovered that he has cockroaches living in his kitchen. He can’t decide if he wants to buy RAID “House and Garden” or RAID “Ultimate Killer”. Both are supposed to be good for killing cockroaches, but one is more expensive than the other. He puts two cockroaches in identical containers that they can’t escape from. One cockroach is sprayed for five seconds with RAID “H & G” and the other one is sprayed for five seconds with RAID “U.K.” The time it takes for the cockroaches to die is timed.

6. Create a food web using the organisms below (You can also add your own). The web should have at least 8 organisms. Human Cow Chicken Fish Grass Corn Mouse Snake Eagle Bacteria Frog Bear Aquatic Plant Water Bug Turtle Raccoon Wolf Rabbit Deer Fungus

7. Identify the trophic levels of each organism

9. Compare and contrast prokaryotes and eukaryotes

10. Observations and Inferences 1.Make 2 observations about the room – 1 must be quantitative, 1 must be qualitative 2.Make 2 inferences about the room

11. Give an example of each of the following: 1.Commensalism 2.Mutualism 3.Parasitism 4.Mullerian Mimicry 5.Batesian Mimicry 6.Aposomatic Coloration 7.Cryptic Coloration
