A good science investigation will involve variables and controls. Without variables you really have nothing to compare your data to. However, it is important to focus on one thing (the manipulated variable) and keep all the other variables constant. Doing so will give your data validity!
In class we practiced how to choose the MV and RV by placing drops of water on a penny.
Homework: Complete questions from Drops on a Penny lab- Questions should be done on page 8 only. If you need more more add a page!
1. Compare your results with what you thought would happen before you completed the lab.
2. Looking at your data, did the variable you choose make a difference? Why or Why not?
3. Describe any variables that may have affected your results.
