I have a host of materials for the acid-base module. The first lab the kids do is Household Acids and Bases, similar to Experiment 10.1, common Household Examples of Acids and Bases. Do a scavenger hunt for common acids and bases: baking soda, salt, lemon juice, clear soda or seltzer water, shampoo, dish detergent, apple juice, Epsom salts, ammonia, etc. This lab has a chart. I instruct the kids to make a prediction before they test. The kids have pH paper in their chem kits. HST sells litmus paper and universal indicator. Use clear solutions whenever possible. Dry chemicals, such as salt or baking soda, must be dissolved in water before testing with pH or litmus paper. Test the pH of water, especially if your water is extremely hard. Below is a video explaining Experiment 10.1 with loads of household chemicals.
