Part A: Rolling down a ramp
Read the box. Then circle the best answer.
A ramp is a slope. Things roll down a ramp because gravity pulls them down.
A steep ramp is high at one end. A gentle ramp is low.
Things go faster down a steep ramp. They often roll further at the bottom too.
- AIt goes slower.
- BIt goes faster.
- CIt stops.
- DIt goes up.
Answer: It goes faster.
On a steeper ramp the car speeds up more, so it goes faster.
- Athe wind
- Bgravity
- Cthe table
- Da magnet
Answer: gravity
Gravity pulls things down towards the ground.
- Ato make the test fair
- Bbecause it is red
- Cto make it go faster
- Dbecause it is new
Answer: to make the test fair
In a fair test we only change one thing. The car stays the same.
Part B: Fill and true or false
Answer: steeper
The higher the end of the ramp, the steeper the slope.
Answer: True
Gravity is a pull towards the ground.
Answer: False
The car rolls faster and further on a steeper ramp.
Part C: Working scientifically: Zoe's ramp test
Read Zoe's results. Then answer the questions.
Zoe made a ramp with a tray and some books. She let the same car go from the top each time. She did not push it.
She counted footsteps to see how far the car rolled. 1 book: 3 footsteps. 2 books: 6 footsteps. 3 books: 9 footsteps.
Answer: The ramp with 3 books (the steepest ramp).
Answer: 6 footsteps.
Model answer: The steeper the ramp, the further the car rolled. The 3-book ramp was the steepest and the car went the furthest.
Success criteria:
- Says what happened as the ramp got steeper
- Uses the results in the table
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
Great work. Here's what to try next:
