一个有趣的工作表，以探索物品是滚动还是幻灯片。
用这个物理科学在讨论日常课堂物品是滚动还是滑动时，请与您的学生进行工作表。
询问您的学生是否认为每个项目都会滚动或滑动。指示他们围绕他们认为会滚动的东西绕圈，并强调他们认为会滑动的东西。
动手卷或幻灯片活动
Make this a hands-on science activity by collecting the items on the worksheet and conducting an investigation. Prop up a flat ramp (this might be a desk that you have raised up on one end or a large piece of cardboard that is higher at one end.) Then, encourage students to see if their predictions are correct by placing items at the top of the ramp to roll or slide to the bottom.
