We recently did an ice cream science experiment had so much fun I wanted to share it with ya'll! Here are the ingredients, directions and a video of what we did... http://takingtimeformommy.blogspot.com/2011/04/science-experiment-ice-cream.html
We made ice cream in ziploc bags before and the kids loved making it, but didn't want to eat it. I thought it was great. Loved your videos.
It does look like a lot of fun. As a physicist, I'm a stickler for method: What is the purpose of the experiment? What principles are involved? What are we measuring? What do we expect to happen? What actually happens? Why the difference (if there is a difference)? You probably answered these questions before and after the experiment, right? What would be really neat is to add a couple of minutes at the beginning and the end of the video so any child watching could learn the lesson as well. And another thing you've made we think of: What about a website at which homeschooling families can upload videos like this for other families to watch and emulate?
Now try it a little differently. See if I can remember.... Put the ingredients in a clean can with a lid (like a small coffee can). Place this inside a larger coffee can. Pack ice in the space around the smaller can. Then you roll the can back and forth between the kids for a while to make your ice cream. Maybe you can compare which took the shorter time or which froze harder or something....?
