1. Chemical Reactions

2. Acid/Base Reactions
When mixing an acid and a base, atoms in compounds can recombine to form new compounds.
One of the most famous is an acid and sodium bicarbonate.
This reaction releases a gas, causing the combined solution to “foam” or “fizz.”

3. Measurements We can measure: Mass Temperature
Distance (height of foam)
Volume (of balloon)

4. Experiment In pairs, you must design an experiment that either tests:
how the chemicals change from before to after the reaction, or…
that tests how changes to the environment affect the reaction.
