Show photos or video from this afternoon’s guided activity. Ask children to describe some of the differences between rolling balls on the rug and on the tile floor. You can add their comments to the photos.
Review the “Different Surfaces and Objects” chart and discuss the textures of the ramps in the video (the couch cushion and cardboard). Ask, We’ve discovered that the texture of ramps changes how different objects roll or slide down them, but what about the texture of the objects going down the ramps? How do you think their texture or shape changes how they roll or slide down a ramp?
