We do a lot of letter, number, and art activities in our house. I thought it would be fun to try a science activity. I found this idea on some homeschooling blog and thought we would try it. First we tried to define the term "dissolve" for the girls. Then, I picked out about a dozen different powders and the girls mixed them in the water, one at a time.
Here is Sabrina trying to mix coffee grinds in water:
Of course Sabrina did some taste tests:
As we were going, we made two posters, one of things that Dissolve and one of things that Do Not Dissolve.
I think the girls loved this activity and seemed to get a little out of it. When they took a bath a few hours later, they used the toy cups and shampoo to see if it dissolved.
