Common Properties of Matter
Atoms, Elements & States
Two students in search of ideas for a science project find help in a store like one they've never seen. Miss Dallerwag, the store owner, helps explain concepts like atoms and molecules. She also describes what mass, volume, and density are and how they are different, and the states of matter and how they change. With the insights and understanding the students gain from this experience, the science project turns out to be a big success.
