Rainy Day Science

With some rainy days here recently, we have had to resort to indoor fun.  What better activity when you are stuck inside than to learn about science!

Here are some of our favorites using common household items. 

Make it rain (in a jar)

Density demo with eggs (did not work the first time for us. You need to use a lot of salt.)

Sink or float?  Or better yet, a Lego boat.
