测试推与拉的设计方案
Testing Push & Pull Designs
分析数据，判断某个设计方案是否按预期发挥作用，即能否通过推力或拉力改变物体的速度或方向。
Analyse data to determine if a design solution works as intended to change the speed or direction of an object with a push or pull
学习证据 / Evidence
- 测试一个简单的设计（如斜坡、发射器），并收集数据判断它是否达到目标。
- 分析结果，判断该设计是否按预期发挥作用。
- 根据数据提出修改建议，以改进设计的效果。
- Test a simple design (e.g. ramp, launcher) and collect data on whether it meets the goal
- Analyse results to determine if the design works as intended
- Suggest modifications based on the data to improve the design's performance
评估问题 / Assessment
如果{{name}}搭一个斜坡让球滚进杯子里，能不能通过测试来发现球没进时该改什么？
If {{name}} builds a ramp to make a ball go into a cup, can they test it and figure out what to change if the ball misses?
