The Homer Scenario Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower. 1. What was the initial observation? 2. Identify the Control Group 3. Identify the Independent Variable 4. Identify the Dependent Variable 5. What should Homer's conclusion be? The Bart Scenario: Bart believes that mice exposed to microwaves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food. He found that 8 out of 10 of the microwaved mice were able to push the block away. 7 out of 10 of the non-microwaved mice were able to do the same. 6. Identify the Control Group 7. Identify the Independent Variable 8. Identify the Dependent Variable 9. What should Bart's conclusion be? 10. How could Bart's experiment be improved?

Bell-ringer: 9/2/15 -Put this on the third box of your bell-ringer page in your composition book. - Write the questions today. 1.All living things are made of ______________. 2.What are those made of? - KEEP your composition book at your desk. Don’t Freak Out… Today you will take a pre-quiz to see what you know about our next unit of study. This is not for a grade, but I want you to try the best that you can. If you don’t know an answer, guess. We may do these before each unit.
