# Ramps

In this lesson, students will learn about how and why things roll, and predict and measure distances using non-standard units.

## Prepare

• Review this lesson plan and choose what you need from the Teacher Support box.

• If necessary, pre-teach these related vocabulary words: ramp, predict, prediction, observe, observation, measure

• Consider the abilities and backgrounds of all your students and decide when and how to introduce and differentiate lesson content, activities, or concepts.

• The Science Behind the Play:

• Several factors will cause an object to roll or slide, beginning with a force (i.e., a push or pull) that acts on the object. Gravity is a force that pulls objects toward the earth or down a slope.
• The shape of an object affects how it moves down a slope. Objects such as balls, which do not have corners or edges, will roll. Other objects will tend to slide rather than roll due to their shape. Size and texture determine the speed of rolling or sliding.

## Connect

• Ask the students to describe what it is like to go down a slide.

• Discuss why/how people move from the top to the bottom of a slide without using their bodies to assist them. In other words, explain that people move down a slide because of gravity, which is a force that pulls objects toward the earth.

• Tell the students that you are going to read the beginning of a story about a group of people who are preparing STEAM Park for its daily visitors.

• You can show them the inspiration photo or use the figures to act out the scene.

• Read the following story aloud:

Parker, the park manager, wants to build a new ride for visitors to enjoy. He asks his neighbor, Ms. Engels, and her grandson Arty and Arty’s friends Sienna and Matt to help.

“Let’s build a ramp and some cars to ride down the ramp,” Parker said.

“I have an idea! Let’s place a line of numbers at the bottom of the ramp and guess how far the cars will roll!” Arty said.

“Great idea! We can try it out and see what works the best,” Ms. Engels said.

## Construct

• Tape or glue all six pages of the track template together to comprise the entire length of the track.

• Working in pairs or as a group, ask the students to take turns placing the bricks to build the two smallest ramps and the sides of the track as shown in the inspiration photo. Make sure the students place the number bricks in the right places.

• Position the smallest ramp on the track template and ask the students to take turns rolling the cars or objects down the small ramp, then try with the bigger ramp.

• Use a pencil to mark where each car stopped. You can use different marker colors to represent the different cars or objects.

• Show the students how to record the result of each roll on their graphs. Make sure they understand that there is a separate graph for each ramp size.

Tip: Each student should have four different results graphs, one for each ramp. This is so they can compare how far the cars or objects will roll after going down each ramp.

## Contemplate

• Ask the students to predict how far a car or object will roll.

• Will it stop between numbers 3 and 4?
• Will it roll all the way past number 10?
• Does it become easier to predict where the car or object will stop after observing or watching what happens a few times?

## Continue

• How can you make a car go faster?

• How can you make a car roll farther?

• Ask the students to build the large ramp that is shown on the in-box building inspiration card. (They will need to use the pieces from the smaller ramps.)

• Tell the students to test the ramp by rolling cars down it, then challenge them to build a car that rolls past the number 10.

Tip: See the image of the larger vehicle in the appendix.

## Did you notice?

• Ask guiding questions to elicit students’ thinking and their decisions while ideating and building. What do you wonder about…? What do you notice…?

Observation Checklist

• Review the learning objectives and educational standards addressed in this lesson (Teacher Support box).

• Share specific student responses and behaviors at different levels of mastery.

• Use the following checklist to observe students’ progress:

• Their investigation plan includes a way to observe and collect the data about whether the car rolls past the number 10.
• Based on their observations of the data collected, students can describe whether the push or the pull from the design of their car causes the intended change in the car’s motion.
• They understand that the numbers at the end of the ramp represent the distance that the car is traveling and that the numbers get larger the farther the car travels.

## Teacher Support

Students will:

• Observe what happens when they place objects on a ramp
• Make predictions
• Measure how far objects move
• Record data using graphs
