Building a Rocket: Exploring Properties of Matter and Their Applications

Justin plans to build a rocket and explores the properties of matter. He explains physical properties like color, shape, and state changes, and chemical properties such as reactivity and flammability. The lesson covers how these properties are crucial for material selection in rocket building. Key concepts include physical and chemical properties, solubility, magnetism, and temperature-related state changes.
