Bounce, Roll, and Slide: Discover How Things Move!

When you drop a rubber ball, it bounces! It hits the floor and springs back up. This happens because the ball is round and made of springy material.

A rubber ball squishes a little when it hits the ground. Then it pops back up fast! Other things like blocks and books do not bounce.

Round things roll! When you push a marble or a ball, it rolls along the ground. It turns over and over as it moves.

A ball rolls down a ramp because it is round. A toy car rolls too because it has round wheels. Round shapes make rolling easy!

Flat things slide! When you push a block on a smooth floor, it slides across. It stays flat and glides along the surface.

A book slides on a desk. A hockey puck slides on ice. Flat bottoms make sliding easy on smooth surfaces.

Bounce: When you drop something and it springs back up, that is a bounce. A rubber ball bounces because it is springy and round.

Roll: When a round object turns over and over as it moves, it rolls. A marble rolls because it has a round shape.

Slide: When an object moves along a surface while staying flat, it slides. A block slides because it has a flat bottom.

Surface: A surface is the flat top of something, like a floor or a desk. Objects move across surfaces when they roll or slide.

Elastic: Elastic means springy. A rubber ball is elastic, so it bounces back up after hitting the ground.

Ramp: A ramp is a slanted surface. When you put a round object on a ramp, it rolls down because of gravity.

Gravity: Gravity is a force that pulls things down. Gravity helps a ball roll down a ramp or bounce down to the floor.

Shape: The shape of an object tells you how it will move. Round shapes roll and bounce. Flat shapes slide.

You can try this at home! Drop a rubber ball and watch it bounce. Then push a block on the floor and watch it slide.

You can also roll a marble down a ramp. Watch how round things roll and flat things slide. This is science in action!

Look around your classroom. Can you find things that bounce, roll, or slide? Think about the shape of each object. Does its shape help you guess how it moves?

You already know that things around you can move! You have seen balls bounce and toys roll. Now you can learn the science words for these movements.

Knowing about bounce, roll, and slide helps you understand basic forces. Forces are pushes and pulls that make things move. You are learning about forces every time you play!

Learning about movement types is part of understanding Basic Forces. Forces are pushes and pulls. When you push a ball, a force makes it roll or slide. When you drop a ball, gravity pulls it down and it bounces back up.

You are building great science skills by learning how objects move. Keep exploring bounce, roll, and slide to understand the world around you!
