If you look closely at your child's Christmas gifts, you're sure to find a lot of science. One of the gifts my 5 year old received was a set of slides for her View Master picture wheel thingy.
She has a ton of different picture reels for her View Master that are mainly Disney based, but this is her first science based picture wheel. As you can see, it is series of pictures based on the first manned lunar landing. Very cool! It's not hard to find excited, science related gifts for your child.
