Lecture 28 - Defining matter. Ask Students how they would describe matter. Have them describe what matter is and what it is not. It is appropriate for them to speculate and argue their point with their classmates. Have them think about the activity from session 1 where they separated substances into smaller and smaller parts. (They might mention elements, atoms, or even subatomic particles.) What might that tell them about matter? Capture their thinking (also ‘wrong ideas’) on the board for later discussion and revision. | Lecture Science 1 - Associate Degree in Education: Lecture 28 - Dr. Arshad Bashir
