Science Experiment Reflection

At the science museum, Omar and Jai tested how different ramp surfaces affect how far a toy car travels. Read their investigation and results, then use evidence to reflect like a scientist. You do not need to carry out the experiment.

The investigation

Question: How does the surface of a ramp affect the distance a toy car travels? Omar and Jai used the same toy car and ramp height each time. They released the car from the same starting line without pushing it. They tested each surface three times and measured from the bottom of the ramp.

Think about the test

Use details from the investigation and results in your answers.

1.What did Omar and Jai want to find out about the toy car?

2.Before looking at the results, predict which surface you think would let the car travel the farthest. Give one reason for your prediction.

3.Which surface had the greatest distance in Trial 1, and what was that distance?

4.Which surface had the shortest distance in all three trials?

Smooth plastic
Felt
Bubble wrap

5.In Trial 2, how much farther did the car travel on smooth plastic than on felt? Show or explain how you worked it out.

6.Omar and Jai kept the car, ramp height and starting point the same. True or false: keeping these things the same helped make the test fair.

TrueFalse

7.The car travelled a shorter distance on felt than on smooth plastic. Use the word friction to suggest why.

8.Did the results support your prediction from Question 2? Write yes, no or partly, then use at least one result as evidence.

9.Suggest one useful change Omar and Jai could make if they repeated their experiment to make their results more reliable.

10.Complete the reflection: “The results suggest that changing the ramp surface…”
