"Charcoal Heat Bags" Trailer

Students experiment with smelly rocks that become fizzy when you add water, and then explode when you put a flame near it! This relates to chemical changes, solids, liquids, and gases, heat, light, and combustion. This video also includes one of Mr. Mac’s crazy stories, “Evil Mister Fred’s Water-powered Motorcycle,” to help students remember the lesson. Difficulty: Medium
