What's the Matter with this one?
This activity is all about solids, liquids , and gases. The materials required are three balloons , a freezer, and water.
I've never done this experiment before . After today, I will probably never do it again. It's not really an activity that will take more than ten minutes once you set it up. That being said as a demonstration, it does adequately represent the three states of matter . Thinking about the differences between them will be entertaining for a bit and supplementing it with like minded experiments will make for a deeper experience. I'd recommend this activity for younger learners only.
