How do molecules behave when heated?
Materials needed
- Chalk or masking tape
Procedure
1. Have several students stand in a group.
2. Mark a border on the floor around the group with chalk or tape. Leave a few inches between the group and the border all the way around.
3. Ask students to move around slowly. Everyone should move constantly, but no one should move fast and there should be no pushing and shoving. They are to try to stay within the border marked on the floor.
4. Now instruct those in the group to move a bit faster. They are still to try to stay within the border.
5. Continue speeding up the movement of the group until they can no longer remain within the line marked on the floor.
6. Discuss what happened as those in the group increased their speed. Ask how this relates to the movement of molecules as temperature is increased.
