My son's Kindergarten class is studying States of Matter, and I am in charge of the cooking curriculum that I would prefer ties into this subject. I have numerous ideas for projects, but this one in particular that I grew up doing is really stumping me. I remember shaking cream in a jar for a while, and we would pass it around to all of our friends, and in the end we had butter. Unfortunately, we have allergies to gluten, wheat, dairy, eggs, nuts, and peanuts in our class, so I'd really love a similar experiment we could do that's essentially allergy-free! This project would be taking a liquid into a solid. Thanks!
