Changes in Materials: Heating and Cooling
Students will observe and describe how heating and cooling can change materials, focusing on reversible changes like melting and freezing.
Key Questions
- What happens to materials when we heat them up?
- What happens to materials when we cool them down?
- Can all changes to materials be reversed?
