Active learning ideas

Observing Movement on Surfaces

Active learning helps Year 3 pupils grasp friction because movement is visible and measurable. When pupils push toys across different surfaces, they see firsthand how resistance changes distance traveled, building intuitive understanding that static explanations may not achieve.

Activity 01

• Outdoor Investigation Session
• 35 min · Small Groups

Ramp Races: Surface Tests

Build ramps from cardboard and cover sections with carpet, wood, foil, and sandpaper. In small groups, pupils predict which surface lets a toy car travel farthest from a fixed height, release it three times per surface, and measure distances with rulers. Groups graph results and share patterns.

Compare how objects move on different surfaces and identify patterns in their motion.

Facilitation Tip

During Ramp Races, remind pupils to push the same toy with the same force each time by marking a starting line and using a consistent hand motion.

What to look for

Give students a small toy car and three different surface samples (e.g., sandpaper, lino, carpet). Ask them to push the car the same way on each surface and record which surface made the car stop fastest. They should write one sentence explaining why.

Activity 02

• Stations Rotation
• 45 min · Pairs

Stations Rotation: Friction Hunt

Set up four stations with trays of surfaces: rough cloth, smooth plastic, bumpy foam, and gritty sand. Pairs spend 7 minutes at each, rolling marbles, timing stops, and noting observations in notebooks. Rotate and discuss as a class.

Explain what causes some toys to slide further on wood than on carpet.

Facilitation Tip

While pupils rotate through the Friction Hunt stations, circulate with a checklist to note who adjusts predictions based on new evidence.

What to look for

Present students with a scenario: 'Imagine you are designing a playground slide. Which surface material would you choose for the slide itself, and which material would you choose for the ground at the bottom of the slide? Explain your choices using the words friction and resistance.'

Activity 03

• Outdoor Investigation Session
• 25 min · Pairs

Prediction Sheets: Toy Challenges

Give each pupil a sheet listing five surfaces and toys. They predict and rank travel distances, then test in pairs on a flat table with gentle pushes. Compare predictions to results and adjust ideas.

Predict which surface would make a toy car travel the shortest distance.

Facilitation Tip

After completing Prediction Sheets, pair pupils to compare results before sharing with the class to build collaborative reasoning.

What to look for

Show students pictures of different objects in motion (e.g., a hockey puck on ice, a sled on snow, shoes on grass). Ask them to point to the object that they think is experiencing the most friction and explain why.

Activity 04

• Outdoor Investigation Session
• 30 min · Whole Class

Outdoor Track: Playground Paths

Mark start lines on playground surfaces like grass, concrete, and tarmac. Whole class releases balls together, measures distances, and votes on pattern explanations. Record weather notes for fair testing.

Compare how objects move on different surfaces and identify patterns in their motion.

A few notes on teaching this unit

Teach this topic by starting with hands-on tests so pupils experience friction’s effects before naming it. Avoid abstract explanations early on, and instead let pupils describe what they see. Use guided questions like 'Why did the car stop sooner on carpet?' to draw out ideas, then introduce the term 'friction' as a shared label for resistance.

Successful learning looks like pupils confidently predicting, testing, and explaining how surfaces affect movement. They should describe friction as a force that resists motion and use evidence from their tests to support ideas.

Watch Out for These Misconceptions

• During Ramp Races, watch for pupils who believe rougher surfaces always stop objects faster regardless of the push.

  After pupils complete their ramps, ask them to reflect in pairs: 'Did the same push on wood and carpet travel the same distance?' Use their data to show how push strength interacts with surface resistance.

• During Station Rotation: Friction Hunt, listen for pupils saying smooth surfaces have no friction.

  Provide ice cube trays or oiled boards alongside dry surfaces. Ask pupils to push a small object across each and describe what they feel, guiding them to recognize friction exists even on smooth materials.

• During Prediction Sheets: Toy Challenges, notice pupils attributing slowing to objects 'running out of push power.'

  After testing, have pupils mark the same starting point on each surface and push repeatedly. Ask them to observe if the slowing happens at the same spot each time, highlighting that friction acts continuously.
