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.


Hot and Cold Volcanoes

Course overview


Endothermic vs Exothermic

Students will learn about endothermic/exother mic reactions, along with activation energy.


Cold Volcano Experiment

Students will write the reaction for baking soda and vinegar producing carbon dioxide and make a volcano experiment.


Hot Volcano Experiment

Students will write the reaction for hydrogen peroxide and yeast to make a warm volcano.
