1. HOMEWORK 8-9: ▪ Review notes ▪ Cinderella Metric Conversion ▪ Lab Measurement Sheet

2. Study for Test!! How do I know if I am prepared? Can you… Explain and breakdown the Scientific Method? Apply the Scientific Method to an example? Explain the most important safety rules? Breakdown an experiments Independent Variables and Dependent Variables? And then graph data from an experiment? Identify a control? Recognize and explain Bias in an experiment? Explain the impact of bias and ethics in science and scientific research?

3. Scientific Method & Safety!

4. Use the scientific method and create a flow chart for the following scenarios: A. Charlie wants to grow the biggest pumpkins ever for Halloween. His brother explains that he needs to use Gatorade on the pumpkin seeds instead of water because Gatorade has more vitamins than water so its more nutritious. How should Charlie proceed? B. Velma is challenged by Daphne to a bike race. Daphne thinks that because her legs are longer that she will be faster. How should Velma and Daphne test this?

5. What’s wrong in the picture? Can you name all of the safety violations? What is the most important rule NOT being followed?

6. Independent and Dependent!

8. Bias and Ethics! What’s wrong with bias? What can cause bias in research? Why does bias compromise ethics? Why are ethics important? The two most common forms of BIAS

9. The Metric System Scientific Units
