Introduction to Friction: Slowing Things DownActivities & Teaching Strategies
Active exploration helps Year 1 students grasp friction as a real, observable force. When children push toys across different surfaces and feel resistance, they connect abstract concepts to their own movements and experiences, building lasting understanding through touch and movement.
Learning Objectives
- 1Identify surfaces that create more friction than others.
- 2Compare the distance a toy car travels on different surfaces.
- 3Explain how friction causes moving objects to slow down.
- 4Design a simple method to increase friction and stop a toy car more quickly.

Stations Rotation: Friction Surfaces
Prepare four stations with toy cars and surfaces: smooth paper, fabric, sandpaper, plastic. Groups release cars from a set height on each, measure travel distance with rulers, and note which slows fastest. Rotate every 10 minutes and share findings.
Prepare & details
Explain how friction helps to stop a rolling ball.
Facilitation Tip: During Station Rotation: Friction Surfaces, place identical toys on each surface and have students predict which one will travel farthest before stopping.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Pairs: Ramp Roll-Off
Partners build adjustable ramps using books and boards covered in different materials. Release marbles from the same height, measure stopping points, and adjust angle to test speed effects. Discuss why rougher surfaces stop rolls quicker.
Prepare & details
Compare the force needed to stop a fast-moving object versus a slow-moving one.
Facilitation Tip: For Pairs: Ramp Roll-Off, remind students to keep the ramp angle the same for every test to ensure fair comparisons.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Whole Class: Stop the Ball
Roll a ball across the floor at varying speeds. Class predicts and tries stopping it with hands, feet, or objects, timing distances. Chart results to compare fast versus slow rolls and vote on best safe method.
Prepare & details
Design a way to stop a toy car quickly and safely.
Facilitation Tip: In Whole Class: Stop the Ball, ask students to stand in a circle and gently roll balls to each other, noticing how far they roll on each surface type.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Individual: Safe Car Stop Design
Students draw or build a device using classroom materials to stop a toy car quickly and safely. Test designs on a track, note friction role, and present one pro and con.
Prepare & details
Explain how friction helps to stop a rolling ball.
Facilitation Tip: During Individual: Safe Car Stop Design, provide small ramps and different materials so students can test and redesign their stopping systems.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Teaching This Topic
Teach friction by letting students feel the force first, then measure it. Begin with a quick hand-rubbing demo to introduce friction as a real sensation. Avoid over-explaining; let the activities reveal patterns naturally. Research shows that early science learning sticks best when students manipulate objects and talk about what they observe.
What to Expect
Students will describe how surface texture affects movement, measure distances traveled, and explain why objects stop. They should use terms like smooth, rough, slow, and fast when discussing their findings.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Station Rotation: Friction Surfaces, watch for students who believe friction only happens on rough textures. Redirect by asking them to compare the smooth tile to the rough carpet and measure the distances traveled.
What to Teach Instead
Hold up the tile and carpet side by side. Ask students to push identical toys across each surface and note which one travels farther. Point out that even smooth surfaces create friction, just less of it.
Common MisconceptionDuring Pairs: Ramp Roll-Off, watch for students who think faster objects experience less friction. Redirect by having them measure the distance each ball rolls after leaving the ramp.
What to Teach Instead
Ask students to roll the ball down the ramp at different starting points and record how far it travels on the same surface. Point out that the ball always slows down, even if it starts faster.
Common MisconceptionDuring Whole Class: Stop the Ball, watch for students who believe objects stop on their own without friction. Redirect by comparing rolling on the floor to rolling on a slick surface like wax paper.
What to Teach Instead
Roll a ball across the classroom floor and then across a sheet of wax paper. Ask students to describe the difference in how far the ball rolls and why.
Assessment Ideas
After Station Rotation: Friction Surfaces, give students a picture of a toy car rolling onto three different surfaces: carpet, tile, and grass. Ask them to draw an arrow showing which surface will make the car stop the fastest and write one sentence explaining why.
During Pairs: Ramp Roll-Off, ask students to hold out one hand flat and rub it against their other hand slowly and then quickly. Ask: 'What do you feel? Is it harder or easier to rub them together slowly?' Listen for responses that describe friction as resistance.
After Whole Class: Stop the Ball, present students with a scenario: 'Imagine you are riding a scooter and want to stop. What are two different things you could do to use friction to slow down?' Listen for ideas like dragging feet, using brakes, or turning the scooter to create more resistance.
Extensions & Scaffolding
- Challenge students to design a surface that stops a toy car in the shortest distance possible, using only the materials provided.
- Scaffolding: For students who struggle, have them trace the path of a rolling ball with their finger while saying 'friction' aloud to reinforce the connection between the word and the feeling.
- Deeper exploration: Introduce the idea of lubrication by testing how a drop of water on a surface changes the distance a toy travels.
Key Vocabulary
| Friction | A force that opposes motion when two surfaces rub against each other. It causes things to slow down or stop. |
| Surface | The outside part or uppermost layer of something. Different surfaces feel rough or smooth. |
| Force | A push or a pull that can make something move, stop moving, or change direction. |
| Motion | The act or process of moving or being moved. |
Suggested Methodologies
Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
