2 Remember Atoms? Where were the protons and neutrons found? Where were the electrons found? How many electrons are in each shell when full?

3 Water Structure Hydrogen How many electrons are needed? Oxygen How many electrons are needed?

4 Water is Polar What is polarity? Why does it happen?

5 Cohesion What is it? Why does it happen?

6 Cohesion How is cohesion important to life?

7 Water Holds its Temperature Well Why does so much energy have to be gained or lost to change the temperature of water? How is this important for life?

8 Water Floats When Frozen Why? How is this important for life?

9 Adhesion What is it? Why does it happen? How is it important to life?

10 Water is a Good Solvent What is a solvent? Why is water good at it? How is that important to life?

11 Water Organizes Nonpolar Molecules Why? How is this important for life?

12 Water Has a pH of 7 What is pH? What is an acid? What is a base? Why is water neutral? Why is this important for life?

13 Properties of Water Polarity Cohesion Holds Temperature Well Floats When Frozen Adhesion Good Solvent Organizes Non-Polar Molecules Neutral pH
