Three toy blocks on ice, carpet and sand each get the same push, and the picture pauses mid-slide to show friction as an arrow pointing back: small on smooth ice, big on rough sand. The blocks then slide on and stop, farthest on ice and soonest on sand, a boat and a toy parachute show that water and air slow moving things too, and it ends on "Less friction means a block slides farther."

Transcript

What the lesson says

Which block will slide the farthest?

This block sits on smooth, slippery ice.

This one sits on soft, fuzzy carpet.

This one sits on rough, bumpy sand.

We give each block the same push.

As they slide, the ground rubs each block.

This rubbing is friction. It slows the block down.

Rough, bumpy sand has the most friction.

Smooth, slippery ice has the least friction.

Now let's see where each block stops.

On ice, the block slides the farthest!

On sand, the block stops the soonest.

Water and air slow moving things down too.

Less friction means a block slides farther.
