Week 2: Down the Ramp

Lesson 4

Children send two objects down a ramp to determine which one is faster. They increase the steepness of the ramp and note how that affects the results.


Circle Time: Introduction

Ramp Rolling   
10 min. 

 

A student and teacher kneel over a gently sloping cardboard ramp. The student holds a pencil in front of two toy cars, to keep them from going down the ramp.

The girls in this video use a starting gate and a finish line as they send two objects down a ramp to find out which one rolls faster. A hands-on demonstration is provided before children watch the video.

Coconut Star: Explore — Which Rolls Faster?   
5-10 min.

Children set the steepness of two ramps and send two identical coconuts down the ramps, comparing their speed. They share ideas about why one coconut rolled faster than the other, or why both coconuts rolled at the same speed.

Guided Small Group

Faster and Slower   
5 min.

 

Students watch teacher slide a binder clip down a ramp made from half a cardboard tube.

Children practice making a binder clip slide slowly and quickly by adjusting the steepness of a cardboard tube.

Which Is Faster?   
10 min. 

 

Students cheer and point after an object has gone down a cardboard ramp that they are sitting next to.

Children send two objects down a single ramp to find out which one rolls faster. They predict what will happen if they increase the steepness of the ramp. Will the same object still be faster? They video record the experiment on the iPad in their digital Ramps Journal, using the Slow It Down Videos tool.

Rolling Marble Art   
5-15 min.

 

A student tilts a tray with a piece of paper, a marble, and some red and blue paint. The marble is rolling and creating patterns with the paint.

Art Center: Children roll paint-covered marbles in a paper-lined box lid or tray.

Listen to It Roll   
5-15 min.

 

Students hold each end of a plastic tube. One talks into one end, while the other listens.

Manipulatives Center: Place a large marble in a sump pump hose (or other wide flexible ridged tubing) and make it roll — fast and slow, back and forth. Listen to the sounds it makes!

Ramps, Pathways and Games: Part 1   
5-15 min.

 

Two students kneel behind cardboard ramps. One student is about to let a round object roll down the steeper of the ramps.

Block Corner: Children build ramps with wide cardboard flats, and use a starting gate and finish line to find out which rolling object is faster.

Digital Learning Center: Children explore how 1) the amount of initial force and 2) the steepness of a ramp affect how far a coconut will roll.

Ramp Rolling   
10 min. 

 

A student and teacher kneel over a gently sloping cardboard ramp. The student holds a pencil in front of two toy cars, to keep them from going down the ramp.

Digital Learning Center: The girls in this video build ramps with everyday objects and do experiments to determine which ball rolls farther and which ball rolls faster. They also invent a bowling game.

Circle Time: Wrap-Up

The Slide   
5 min.

 

A student smiles as she demonstrates a sliding motion using her fingers on her own arm.

Children discuss experiences with playground slides then learn the fingerplay, "The Slide."

Imagination Adventure   
5 min.

 

Students close their eyes and wave their arms in the air.

Children close their eyes and imagine they are sliding down a long slide, first gentle and slow, then steep and fast!

And Everyone Shouted, 'Pull!'   
10 min.

 

A teacher holds up a book in front of students seated on the floor.

Children join in with the story with motions, words, and song, focusing especially on the fastest and slowest parts of the journey.
