STEMonstrations: Physical and Chemical Changes
Do you know the difference between a physical and a chemical change? In this STEMonstration astronaut Sultan Alneyadi will explain the differences between these two types of change in matter while demonstrating examples of physical and chemical changes that happen aboard the International Space Station every day. In the corresponding Classroom Connection, students explore chemical weathering by performing experiments to test reaction times of different chemicals on a variety of everyday materials.
