Second grade scientists used Oreo cookies to create the eight phases of the moon. When the moon is growing smaller, it is waning and when it appears to be growing, it is waxing. Remember: Light on the right, the moon is getting bright! Click here to watch a video about the moon. Click here to check today’s moon phase.
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.
