More Mad Science

Here is a quick review of some of the science experiments that we have done over the last week. Derek loves to make messes with science. Thanks to http://www.stevespanglerscience.com/, I have a pretty good supply of fun science materials...
Here are some UV beads that only change color in sunlight. Other types of light don't work.
And here is Derek experimenting with diffrent types of polymers. The powder for this experiment is the same stuff that is also used in diapers to absorb moisture. It expands and holds water...and gets cold. It is "Dehydrated Snow"...:)This is another type of polymer that becomes jelly like when it absorbs moisture. Derek decided to make it green.
Color mixing experiments with Braxton.
The colors look so pretty...Derek is learning that he can make 100's of shades of green.
