Students burn a magnesium strip to reinforce the concepts of chemical vs. physical changes, reaction types, conservation of mass, formulas and equations, stoichiometry, Lewis structures, and to explore the concept of oxidation/reduction...

This chemistry science fair project uses a very simple experimental setup - a battery hooked up to two solutions, connected by a salt bridge - to explore some complex chemistry. The Science Buddies project ideas are set up consistently...

[Free Registration/Login may be required to access all resource tools.] Students distinguish between substitution reactions and addition reactions, and relate the concepts of oxidation and reduction to organic reactions.

This digital textbook covers core chemistry concepts and includes interactive features, real-world examples, and videos.
