Week beginning 31st January: gravity & friction...

Continuing their physics experiments, students investigated the forces of gravity and friction upon moving objects. 

P7 designed two experiments:

- Comparing the use of different surfaces on a ramp with a vehicle to see when friction was at its strongest and weakest.

- Constructing their own parachute design for an egg, using air resistance to reduce the gravitational force. 

In both experiments, Primary 7 pupils first made a hypothesis as scientists, discussed the importance of a 'fair test' before carrying it out.

The findings were then used as an interdisciplinary context for our report writing on Thursday - some brilliant explanations of what happened!
