Change in Temperature: Endothermic Reaction
Source Institutions
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
Reaction: Yes or No?
Source Institutions
In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.
Edible Ink
Source Institutions
In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.
Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.
