We have had so much fun this week conducting experiments that have caused states of matter to change! Each kid was given a bag of ice and had to figure out a way to make it change from a solid to a liquid. Students ran them under hot water, wrapped them in their coats and rubbed it back and forth on the table. They quickly figured out that by adding heat a solid changes into a liquid. We also went through the process of making Jell-O and took a look at the gas (water vapor from boiling water), liquid mixture and sold (froze the cups in the freezer). We then let the Jell-O thaw to see if it would change back into a liquid (which it did a little bit). We also blew up a balloon with the gas formed by mixing vinegar and baking soda. Last we made raisins float and sink by using carbon dioxide in clear soda.
