It is summer break, but in our family the fun and learning never stop! Today we took the time to have fun with some different chemical reactions. We did a classic volcano using vinegar(3/4 cup) and baking soda(3 teaspoons), and something much more fun which seems to be called "Elephant Toothpaste".
|Classic Volcano(anyone else remeber that being cooler)|
The Elephant Toothpaste was far more exciting and a much better representation of the decomposition of Hydrogen Peroxide.Here is what you will need:
- An empty 20 oz soda bottle (or any tall skinny clear container)
- Hydrogen peroxide (you can get 3% at the grocery store)
- Active yeast(1 package)
- Warm water
- Liquid dish soap
- Food coloring - optional - but hat isn't more fun with color ;o)
Now we messed up on ours and forgot the warm water(which explains why all the other ones were cooler.lol) But here is how it is done!
- Mix,4 oz of hydrogen peroxide with 2oz of liquid dish soap and a few drops of food coloring. Add this mixture to the soda bottle and place it in the sink(or pan).
- In a separate container, mix one packet of active yeast with warm water, still and let sit for 5 minutes.
- When you are ready, pour the yeast mixture into the soda bottle (a funnel might be helpful) and watch the reaction!
Now really you can do this just for fun it doesn't have to be a learning task. To use it as a learning task make some simple observations with your child and discuss why things happen. Have fun!
