I have a degree in Chemistry and currently I am doing graduate courses in Statistics. There are many interesting fields to pursue with Chemistry and Statistics. But I want to solicit from you guys any suggestion on what would be the most rewarding field of endeavor I could pursue. I would appreciate answers from the more senior and more experienced answerers. (add info: I enjoy data interpretation more than the actual laboratory work)

Three questions really:

1. How many different types of atom are there?
2. How are electrons generated/formed?
3. Are there any scientific links between the layout of the atom, and that of a 'solar system'?

I'm an art teacher assigned to a special school science project based on Legos. Lego sponsers a sci project for elem kids where they have to build a lego replica of their research. The topic this year is "where energy comes from." Our project is to research anything, and find out where the energy comes from (ex: a clock runs on batteries, batteries work because of acid, this acid comes from. . . )

My fourth graders are dead-set on researching this info for toilets. I understand that toilets work using a siphon (what type of energy if any is that?), do all toilets use pumps? If so, where does that energy come from?

I know where our water supply comes from (a river) and where it goes after we flush (a waste treatment plant).

If you have any guidance as to where all of the energy comes from I would really appreciate it. We are SERIOUSLY in over our heads.
