力的探究
Investigating Forces
规划并开展力的探究活动，包括使用弹簧测力计测量力、探究胡克定律，以及收集和解读运动数据来验证牛顿运动定律。
Plan and carry out investigations into forces, including measuring force with a newton meter, investigating Hooke's Law, and collecting and interpreting motion data to test Newton's laws
学习证据 / Evidence
- 能正确使用弹簧测力计，以牛顿为单位测量力。
- 能设计并开展胡克定律探究，记录力和伸长量并绘制图表。
- 能在力的探究中识别并控制变量。
- 能根据力和质量的数据计算加速度，并与实验结果进行比较。
- Uses a newton meter correctly to measure forces in newtons
- Sets up and conducts a Hooke's Law investigation, recording force and extension and plotting a graph
- Identifies and controls variables in a force investigation
- Calculates acceleration from force and mass data and compares with experimental results
评估问题 / Assessment
如果{{name}}设计一个实验，在弹簧上挂重物并测量弹簧被拉伸了多少，那么{{name}}能否说明怎样做才能保证这是公平测试、如何记录结果，并用图表展示胡克定律的表现？
If {{name}} set up an experiment hanging weights on a spring and measuring how much it stretched, could they describe how they would make it a fair test, record the results, and show what Hooke's Law looks like on a graph?
