Big Questions in Science

Children are naturally curious and are forever asking questions.  Maybe, as parents, you don't know the answers to all of their questions about the world, the universe, nature, science, etc.  Every week of this ongoing class will tackle one of these fundamental questions of science, but using an approach and language for kids.   Each class will have some basic information on the topic, some kind of activity for the kids to do, and a discussion/question-answer period. 
  
The first four weeks' topics will be: 
1) What are atoms and molecules?
2) How are plants and animals similar and different?
3) What is the Big Bang Theory?
4) How does the human body work?

Future topics may include: fossils, plate tectonics and continental drift, the Water Cycle, light and sound, cells, electricity, magnetism, evolution, rocks and minerals, gravity...
