Friction Ramp Test is a free printable science worksheet for Year 3 (ages 7 to 8). Children ask which surface makes a toy car go furthest. They predict, test and measure, then record each result in a table. It takes about 20 minutes. You need a ramp, a toy car and a tape measure. Page 2 gives the grown-up notes, help, a stretch idea and the answers.
It comes from the Mini Minds Hub, the free library of printables from Jaques of London, the British games and toy company that has been making games for families since 1795. Print both pages, give page 1 to your child and keep page 2 for yourself. Black and white printing works well.
What is on the sheet
Children test how different surfaces change how far a toy car travels. They use a ramp, a toy car and a tape measure. They fill in a table with three columns: Surface, My guess and Distance in cm. The sheet practises predicting, measuring and fair testing. As a next step of our own, you could compare the guesses with the measured distances and talk about what the results show.
- Surface
- My guess
- Distance in cm
Setting up a fair test
Choose a ramp
Use a firm, flat board or tray propped on a pile of books. Keep the slope exactly the same for every run.
Mark the start
Put a piece of tape on the ramp. The car starts from the same mark every time.
Let go, do not push
Release the car gently and let the ramp do the work. A push would change the test.
Measure the same way
Measure from the same place each time, to the same point on the car. Write the number straight away.
What is friction?
Friction is a force that acts when two surfaces rub or slide against each other. It acts against movement, so it can slow a moving object down or make it harder to start moving. You cannot see a force, but you can see what it does. That is why a toy car is a good tool for showing it.
In Year 3, children begin to compare how things move on different surfaces. A science test works best when children change only one thing and keep the rest the same. Here, the surface is the thing that changes. The ramp, the car and the start point stay fixed, so the results mean something.
Fun facts about friction
- Friction is a force. It happens when two surfaces rub against each other.
- You can feel friction making heat when you rub your hands together quickly.
- Bike brakes use friction to slow the wheels down.
- The tread on shoes and tyres is there to help with grip, which comes from friction.
- Scientists measure force in units called newtons.

What children will be able to do
- I can predict how far a car will travel on a surface.
- I can run a fair test and record the results.
- I can say which surface gave the most friction.
Science ideas behind the sheet
- ForcesA force is a push or a pull. Friction is a force that acts when surfaces touch and move against each other.
- Fair testingIn a fair test you change one thing and keep everything else the same. That way you know what caused the result.
- PredictingA prediction is a thoughtful guess. Children should say why they think it, even if the reason is simple.
- MeasuringMeasuring in centimetres means starting at the same point each time. A small change in where you start can change the number.
Key words
- FrictionA force that happens when two surfaces rub or slide against each other.
- SurfaceThe outside layer of something, such as the top of a table or a mat.
- PredictionA guess about what will happen, made before you test.
- Fair testA test where only one thing changes and everything else stays the same.
- DistanceHow far something travels. We measure it here in centimetres.
- ForceA push or a pull.
How to use it
- Print both pages. Page 1 is for your child. Keep page 2, which has the notes and answers.
- Gather a ramp, a toy car and a tape measure. Mark a start line on the ramp with tape.
- Read the table together. Ask your child to write a guess for each surface before any testing.
- Test each surface in turn. Release the car from the same mark every time, measure the distance and write it in the table.
- Check against page 2. Ask, "What did you keep the same?" and "How close was your guess?"
Help, stretch and game ideas
If it feels too hard
A grown-up can help measure and write the number. Test one surface at a time and say each step out loud. Mark the start with tape so the car always begins in the same place. Read the tape measure together, starting from zero.
To stretch confident children
Add two more surfaces to the table. Before testing, predict where each one will come in the ranking, from furthest to shortest. Then test them and check. Ask your child to explain any surprises using the word friction.
Make it a game
Make a bet with a friend about which surface will win. Each player writes a guess before the test. Run the car, measure the distance and see whose guess was closest. Swap who picks the surfaces next time.
Mistakes to watch for
Watch forThe car is given a little push on some runs, so the distances are not comparable.
Try thisLet go of the car gently without pushing. Mark the start with tape and release from the same spot every time.
Watch forThe tape measure starts in a different place each time, so the numbers jump around.
Try thisChoose one point on the ramp and one point on the car. Measure between those two points on every run.
Watch forA different car or a different ramp height is used part way through.
Try thisKeep the car, the ramp and the slope the same. Only the surface should change.
Talk about it
- What do you think will happen on this surface, and why?
- What are you keeping the same to make the test fair?
- How will you know where to start measuring?
- Were any results a surprise?
- Where do you notice friction in everyday life?
- What would you change if you did the test again?
Take it off the page
Grip hunt
Look around the house for things made to grip, such as shoe soles, bike tyres and jar lids. Talk about why grip helps.
Slide test
Prop up a tray and slide a small block down it. Cover the tray with different cloths or papers and see what changes.
Draw the results
Draw a bar for each surface, with longer bars for longer distances. Use the bars to order the surfaces and talk about them.
Who it is for
Parents
Sit with your child for the first test, then let them lead. Let them write their guesses before any testing, even if they are unsure. Focus on what they notice, not on getting the guess right.
Teachers
Use it as a practical starter, a table activity or part of a forces and magnets topic. It needs only a ramp, a toy car and a tape measure. Groups can compare results and discuss why they differ.
Home educators
This works well as a rainy day experiment. Use items from around the house for the ramp and surfaces. It pairs well with books about forces and with everyday talk about grip and sliding.
Where this fits
Before this, children notice how things move and talk about pushes and pulls. Here they begin to compare how objects move on different surfaces and to run a simple fair test with measurements.
Later, in upper Key Stage 2, children study forces in more depth, including friction, air resistance and water resistance. Fair testing, predicting and recording results carry on through all of their science.
Check it worked
Ask these when the sheet is finished. Listen for the reasoning, not just the answer.
- What did you keep the same to make the test fair?
- Which surface slowed the car most, and why do you think so?
- How close was your prediction, and what did you learn?
Questions parents and teachers ask
- What age is Friction Ramp Test for?
It is written for Year 3 (ages 7 to 8), in Key Stage 2. It fits the forces and magnets strand of the National Curriculum for England. Confident Year 2 children may enjoy it with help, and older children can use the stretch idea.
- What do I need to do the test?
You need a ramp, a toy car and a tape measure. A firm board propped on books works well as a ramp. You also need a few different surfaces to test, plus a pencil to fill in the table.
- How long does it take?
It takes about 20 minutes. Setting up the ramp and testing each surface is most of that time. Working through the sheet with your child the first time is a good idea.
- What if it feels too hard?
A grown-up can help measure and write the number. Test one surface at a time, mark the start with tape and read the tape measure together. Come back to the sheet another day.
- Is it free?
Yes. It is free to print for home and classroom use. You can print it again for brothers, sisters or another group, and repeat the test on another day.
- Can teachers use it in class?
Yes. Teachers can use it as a starter, a table activity, an early finisher task or part of a forces topic. It needs no preparation beyond printing and gathering a ramp, a car and a tape measure.
- Do I need to print in colour?
No. It prints well in black and white on plain A4 paper. Page 1 is for the child and page 2 is for the grown-up, with notes, help, a stretch idea and answers.
