4. What is Chemistry? The study of how atoms combine into molecules (and larger structures). What do chemists do? Chemists make and study molecules.

5. What are the most serious problems in the country? Chemistry. What good is it, anyway?

6. Tamiflu

8. Thinking like a chemist: First class assignment How many golf balls will fit in this room? You have 5 minutes.

9. Diameter of a golf ball = 1.68 in

10. What if the golf balls were: too small to touch? individually invisible?

15. Why is chemistry hard?

16. Atoms are really small. About 100 types of atoms (each a chemical element). Matter is made of atoms, mostly connected together in molecules and larger structures- infinite variety of combinations. Lots of math.

17. Why is chemistry useful?
