When I demonstrated some changes in materials caused by heat, students were required to diagram and explain the changes. Each explanation must include diagrams and explanations.
- an illustration of the materials before and after being heated
- molecules and arrows to show the movement of the molecules (Use longer arrows for faster movement and shorter arrows for slower movement.)
- how the heat affected the materials uing complete sentences
- why the heat caused that effect on the materials
We started taking notes on the Behavior of Gases, which correspond to the reading and workbook pages on p.60-64.
