Today as I was browsing around on teaching blogs, I found this amazing science experiment site that has LOTS of fun things to do with kids. For the July 4th holiday, he came up with an exploding experiment that was so much fun! I am going to give it a try with my kids this week. For a kid friendly recipe click here.
Steve Spanglers science blog is a great find and I hope you take a minute and look. Lots of fun things to try.

Domino Fall Down
Do you remember playing with dominoes and standing them on their edge and getting a few in a row to knock them down? We had a lot of fun doing this as a child and didn't even know we were playing with science. The domino has potential energy and when it falls, it's potential energy turns more into kinetic energy. It hits the other domino and it starts the same process. Creating the phrase we've all heard, "Domino Effect".
You don't need dominoes to have fun with this concept, use your building blocks from home or if you have a large supply of food storage, use your cereal boxes or cracker boxes to create a path. At first, keep it simple and do just a straight line. If the children are older, allow them plenty of time to explore with these things and see if they can do different things with them.
Ask open ended questions about the process as it happens.
What is happening when the first box (or block) falls?
If you move the boxes closer (or farther away), what happens?
How do we make our line turn?
What other ways can we set up the boxes and still have them fall down?
Let me know how your experiments go. -click this Youtube video of an amazing domino knock down.
Here are my kids making a domino knock down. We did a small scale one first to teach the concept and then we decided to do a large one...needless to say-one little wiggle and the whole thing falls down. We had a great time.
