What is a Chemical Reaction?
When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass concretely.

Is It Alive?
Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or not.
