摩擦力与表面
Friction & Surfaces
比较物体在不同表面上的运动情况，意识到有些表面产生的摩擦力比另一些表面更大
Compare how things move on different surfaces, noticing that some surfaces create more friction than others
学习证据 / Evidence
- 观察并比较同一个物体在至少三种不同表面上的运动情况
- 描述粗糙表面比光滑表面更容易让物体慢下来
- 使用“摩擦力”一词来解释为什么物体在不同表面上的运动情况不同
- Observe and compare how the same object moves on at least three different surfaces
- Describe that rough surfaces slow objects down more than smooth surfaces
- Use the word 'friction' to explain why movement differs on different surfaces
