Change in Temperature - Exothermic Reaction
Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...
Cornell University
Chemical Reactions
Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

Energy Changes in Chemical Reactions
The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Controlling Chemical Reactions
Young scholars study chemical reactions and how to speed up or slow down one. In this experimental lesson students participate in an activity that allows them to observe chemical reactions.
Santa Monica College
Single and Double Displacement Reactions
If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...
