Yesterday E was playing with this slime we made, and she said that she was doing a test. I asked her what she was testing, and she said that if she held the slime up and hit it with the knife, she wanted to see if it would go to the left or the right. "Like on Mythbusters! They test things."
I said that she was right. They do experiments. She said, "No they test things." So I explained that is what an experiment is- testing a hypothesis. I gave her some examples.
Then she said "My hypothesis is that if I hold the slime up, it will be easy to cut." Then she did it and said, "And it's true!"
She did a few other tests to see of the slime would fall one way or the other, and if it was easier to cut with a steak knife or a butter knife.

Inevitable Learning- Experiments
No longer Inevitable Mondays, because I rarely get around to recording what actually happens on Monday and I can just do Inevitable Learning posts any day of the week!
We usually go to the library story time on Wednesdays, but today I had one kid who didn't want to and one kid who did. I didn't really want to go either, so I suggested that we read some books and do a craft at home instead.
Instead of a craft, I decided to look up a science experiment, because last night we were watching Mythbusters and E wanted to do experiments like them. Most of their experiments involve blowing things up, however, and I doubt our mobile home park management would approve. So I opted for making completely non-lethal tornadoes and freezing salt water.
The tornadoes connected back to an interest in tornadoes that came up a few weeks ago. We used these instructions on youtube, but the only glitter we had is glitter glue. So we tried it! We ended up with globs of it that we pretended were houses and barns and things getting picked up by the tornado. It's hard to see in the video, but it actually creates a tunnel effect.
The freezing salt water experiment just sounded fun. We put two cups of water in the freezer- one freshwater and one salt water. We'll take them out in a little while and see which one froze harder.
