Fair Testing

We are learning about forces.

We made ramps and let cars run down the ramps and measured how far the cars went. We changed the height of the ramp to find out if it made a difference. 

We had to keep everything else the same so it was a fair test.

We had to keep the same car and work on the same surface eg. concrete, lino, carpet.

travelled

The Ruby's testing their steepest ramp.
This car crashed every time. 

The boys worked so well together carrying
out their experiment

We found out that the steeper the ramp the further the car travels.

We also worked out if the ramp is too steep the car crashes, we thought that is why roads are not super steep for cars to drive down. 

Bowen and Logan found out the surface the car travels on changes how far the car travels.

They began their experiment on the lino and then moved to the concrete.

The car did not go as far on the concrete. The boys felt the concrete and the lino and explained to Room 8 that the bumpy concrete slowed the car down.

We learnt it was called

FRICTION 

and I think that will be our next experiment! 

Thanks boys for sharing your learning.
