Anyway, to end the week, we want to share this fun way to teach chemical reactions. It's called Elephant Toothpaste, and it's a big hit with kids who love hands-on learning!
Here's the recipe,courtesy of Scientific American:
A plastic bottle
Dry yeast (found in the baking section)
Liquid dish soap
3% hydrogen peroxide
A tub, bowl, or tray to catch the foam
Liquid food coloring (optional)
Different-shaped bottles or glasses (optional)
Follow the full procedure for combining ingredients, and then observe the results. You can also follow-up with these resources to dive deeper into the science concepts behind Elephant Toothpaste:
