For Science Saturday I thought I would highlight a science experiment that is easy to do and doesn't require a lot of items.
Bouncy Popcorn Kernels are fun to watch.
You will need:
A clear container - I used a vase
Communication Board - this is one I used from Minspeak
I started by showing the children the items we were going to use and asked them "what", "do", "this"?
"What are we going to do with this?"
It's important to use a communication board yourself so that the children see one in use.
We can't expect children to do something they don't see us doing.
We start with the container (It doesn't matter that we don't have the exact words we need. We use what the children have to describe what we are using/doing) and fill it with water.
We added a tablespoon of baking soda and stirred it up.
We talked about what we needed to use to stir the water up.
We "put" in the kernels. Just enough to cover the bottom.
Then we added some vinegar. I found using a small measuring cup easier than a spoon for children with fine motor issues (less spillage).
We "look"ed to see what happened to the kernels.
We took "turns" looking a the popcorn and seeing what was going on in the container.
Everyone said they "like"d it.
We let it sit and kept looking at it throughout the day. After awhile, the popcorn stopped moving and most of it settled on the bottom.
Even an hour later, the odd kernel was still going up or down.
I hope everyone is enjoying their 4th of July celebrations. In honor of my American friends, I'm having a sale to celebrate.
