On Friday we had Mary come from Mad Science with her cooler full of dry ice. We had already learned about solids, liquids, and gases, and had talked about how when solids changed to liquids we call it melting, and when a liquid changes to a gas it evaporates. Mary taught us a new word: sublimate. That describes what happens when matter changes straight from a solid to a gas. We had lots of fun watching her experiments, including blowing up a balloon with carbon dioxide, and hearing a warm spoon screech when it was held against the block of dry ice. The highlight was the dry ice shower! Each person got to catch a bubble filled with carbon dioxide, so much fun!

Thank you for teaching them such interesting science projects. Sage LOVED this one with the dry ice.
