Exploring Properties of Matter

In this video, Justin announces his plan to build a rocket and uses it as a context to teach about the properties of matter. The lesson covers both physical and chemical properties, explaining how they can be observed and measured. Physical properties include characteristics like color, mass, and solubility, while chemical properties involve reactivity and flammability. The video concludes with a review of the key points and encourages viewers to explore further.
