Heating & Cooling Changes
加热与冷却变化
Description
Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
Mastery Evidence
- Describe melting (solid to liquid) and freezing (liquid to solid) with everyday examples
- State that water freezes at 0°C and boils at 100°C
- Explain that heating adds energy causing particles to move more, leading to state changes
Assessment Prompt
Can your child explain what happens to an ice cube when you heat it, and at what temperature water freezes and boils?
