- Observing the Formation of a Gas. The first experiment is very simple, showing children how to tell if a chemical reaction has occurred by observing the formation of gas.
- Show How a Chemical Reaction Can Produce Heat. Next, we have an experiment that shows how a chemical reaction can produce heat. Materials Needed. 1 tsp of yeast.
- Show the Formation of a Solid. Next up is the formation of a solid. You can also use baking as an example for this—bread is formed and cannot be separated back into flour and water, but this one is more fun.
- Show the Occurrence of a Color Change. The last thing to look for when trying to tell the difference between chemical and physical reactions is the occurrence of a color change.
