Acids and Bases
In order to explain acid rain to my third grade environmentalists, we began with a lab about acids and bases. My chemists used a natural indicator (red cabbage juice) to determine if tonic water, lemon juice, vinegar, baking soda, Lysol, and dish soap are acidic or basic. I demonstrated how to make the indicator with red cabbage leaves and distilled water in my Ninja. Click here for directions to make the indicator. Distilled water is neutral (pH 7). We also tested some additional liquids prior to working with our lab partners.
Watch this video to better understand our investigation. We watched the first six minutes.
Do you check the pH in your pool, garden, or fish tank? Be sure to include your child when you do. Click here to learn more about acid rain.
