Weekly blog by Caden and Chloe S
This week we have being learning about forces in Science. In groups we carried out an investigation to find out how much force is needed to move a toy car on different surfaces.
Prediction: it will take more force to move on a rough surface
- A toy car
- 3 rubber bands
- a pencil
- a ruler
- different surfaces
Method: attach an elastic band to the front of the car using tape, we then used a pencil to pull the band and measure how far it stretched before the car moved.
To make it a fair test, things we kept the same (Controlled variables)
- the car
- the same elastic bands
- and where we measured from
Conclusion: We found out that it takes more force to move the car on rougher surfaces.
What we learned during the investigation:
Chloe – “I learnt that some surfaces required more force to be able to move the car.”
Caden- “I found that grass was the roughest surface that we tested”.
Thank you so much to Chloe and Caden for taking part in Class 3’s blog, take a look next week when another two members of our class share their views on another part of our learning journey this term.
