Brain Breaks are powerful tools in education, supported by research showing improved focus, retention, community building, and reduced stress among students. When structured using chemistry principles, like in the Water Maze Race, brain breaks can also introduce or reinforce fundamental chemistry concepts.

Learn the chemistry behind the reaction between calcium carbide and water...melon...?!
Describing the number density of molecules involved in chemistry demonstrations while presenting those demonstrations can help to convey concepts such as the small size of molecules and how the distance between molecules can vary during change of physical state.
You can solve Chemical Mystery #20 if you know your chemistry...and your magic!
Balloons that inflate using carbon dioxide produced from the reaction of citric acid and sodium hydrogen carbonate can be used to demonstrate a number of aspects of chemistry. Gas laws were used with the balloons to illustrate limiting reactants, molar mass of gases, and rockets. The endothermic reaction in the balloon was visualized with an infrared camera, and the Green Chemistry aspects of these balloons were considered.
