About the course

What drives chemical reactions to occur? Why doesn't my coffee suddenly burst into flames when it’s exposed to oxygen? All chemical reactions involve energy. Using a cold and hot volcano experiment, you will examine how energy is given off or taken in to make chemical reactions occur.

Embrace the science of chemical change! This week's topic is all about reactions and transformation.
