2. Question: What are different ways you can protect yourself from UV rays? 1.Decide which type of UV protection your group will test. 2.Come up with a testable question (be specific!) you have about its effectiveness.

3. 3. Design an experiment that investigates the effectiveness of this type of UV protection using UV Beads and the sun.

4. Your Experiment May Use: Six Petri Dishes (*plus one extra if needed) 30 UV Beads (ex. 5 each trial) Plastic wrap over each dish (required if using sunscreen lotion or chapstick) Black paper Stopwatch

5. By the end of this class, I can: Write a testable question & hypothesis and design an experiment to give me reliable test data. My Learning Target

6. Things to think about and have figured out TODAY: What type of UV protection will we choose? What question do we want to test? What are my variables: MV, RV, Controlled? How will I ensure my data are reliable? (That means including a Control Group!! What do I need to bring for my group? (Don’t forget to bring your stuff!).

7. For NEXT CLASS: Each group member needs to have written: Question - including MV, RV Hypothesis - yours may be different from team members. OK if you disagree, as long as you are running same experiment. Complete Procedures - include a Control Group! Data Table - set-up and ready to record data
