加热与冷却的变化
Heating & Cooling Changes
观察并描述一些材料在加热或冷却时会发生状态变化，并用摄氏度测量变化发生时的温度。
Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
学习证据 / Evidence
- 用日常生活中的例子描述熔化（固体变为液体）和凝固（液体变为固体）。
- 说出水在0°C结冰，在100°C沸腾。
- 解释加热会增加能量，使粒子运动加剧，从而导致状态发生变化。
- 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
