Grade 4 matter and materials
Solids, liquids and gases, properties of materials, mixtures and reactions. Here is what we have for Grade 4.
Lessons
Winter Science: Ice, Snow and Staying Warm
Why roads get salted, which mitten really works, how a seal stays warm in icy water, and why a mouse is cosier under the snow than on top of it. Four hands-on lessons on ice, heat and insulation.
Kitchen Chemistry for Families
Four famous kitchen experiments, done properly: a homemade lava lamp, oobleck, a baking soda volcano and invisible ink. Each one starts with a real question, works with things from your cupboard, and leaves your child able to explain what happened.
Keep It Cool: Ice, Insulation and Staying Comfortable
Why salt makes ice melt faster, which wrap keeps a drink coldest, how a seal and a fennec fox each keep their body temperature steady, and how to build a cool box that beats the heat. Four hands-on lessons that start from a freezer and work in any climate.
