A Few Science Experiments

Just wanted to share some pictures of a few of the science experiments we have done in school lately.  (I use the term "lately" loosely as this dates back to January....geez, I'm so far behind on my blogging....eek.)  Either way, here goes...........

A Volcano

We made a volcano out of clay, baking soda, vinegar, and food coloring (if I'm remembering correctly).  The girls got a kick out of it.  We did this last year, too, but it didn't erupt as well as this years. 

 

Rock Candy

Here are a few pictures of us making rock candy.  This was obviously about learning principles of evaporation and crystallization.  The kids really enjoyed this.  They took turns breaking the top layer each day.  And, though, my kids will eat some crazy candy, neither of them ate this.  Weird.

Lung Capacity

This experiment was to sort of test lung capacity.  We were talking about volume, etc.  They took turns doing this and both were able to blow out all of the water.  They were so excited!
