Now that it’s summer, move your science lab outside and try doing the Tablecloth Trick or Throwing Eggs.  If you’d rather check out the power of the sun, try making a solar oven from a pizza box!  You probably have everything you need for these experiments right in your kitchen, and if you don’t have a pizza box, just save one next time you order out.

What are you waiting for?  Have fun!

Here’s a quick experiment for bored kids:

You’ll need a button, a glass, water, and a carbonated beverage.

Pour some water in the glass.  Drop the button in.  What happens?

If it sinks*, dump the water out and fill the glass with carbonated beverage.  Drop the button in.  Now what happens?

The button is more dense than the water and sinks in uncarbonated water, but in a carbonated beverage, carbon dioxide bubbles form on the button and make it buoyant, so it floats to the top.

What other sinking objects can you make float with carbonation?

If your kids like this, check out this Float or Sink experiment that even very young kids can do!

*If your button floats, the experiment won’t work, so try to find one that sinks!
