Week 3: Rolling Down a Pathway

Lesson 7

Children explore how texture and friction affect how far and how fast objects slide and roll.


Circle Time: Introduction

Smooth, Fuzzy, Bumpy   
5-8 min.

 

A seated student feels a piece of bubble wrap as another student looks on.

Children pass around items with different textures and describe how they feel. Then they compare how it feels to skate in sock feet on a smooth floor versus a fuzzy carpet.

Guided Small Group

Textured Blocks   
5 min.

 

A cardboard ramp supported with wooden blocks is set up on a table. A student slides a block, covered in textured material, down the ramp.

Children send blocks wrapped with different textures down cardboard ramps and compare how far they slide.

Ramp Rider   
10 min. 

 

A student holds up a pink stuffed dog that she has placed in a plastic tub.

Children try to slide a stuffed animal down a cardboard ramp, then devise a slippery "sled" that will let the animal slide more smoothly. They record "before" and "after" videos.
