Year 5 (Class 13) - Science - Levers, Pulleys and Gears

This week in science class 13 have been investigating levers, pulleys and gears. They were given a group of everyday objects that they had to classify into the 3 groups.

The children then completed a levers investigation where they moved the pivot and saw the effects of the force needed. They concluded that the pivot closer to the load needed less force. 

We also investigated the effects of gears on bikes. The children concluded that 1st gear needed less force- this was ideal for riding uphill.

They also concluded that 6th gear needed more force- this was ideal for riding downhill.
