Levers, Gears and Pulleys in Maple Class

posted in: Maple | 0

As part of our Science work on forces we investigated how levers, gears and pulleys work.  We had a great time learning how they work and exploring these different mechanisms.

Throughout our learning we found out what a pulley was, how it works and decided which of the different pulleys made it easiest to lift the weights.

When exploring the gears we saw that when you turn one gear the one next to it moves in the opposite direction.  We also learnt how to calculate the gear ratio by counting the number of teeth on the different cogs.  This meant we could work out how many times one gear moved in relation to the one next to it.

We saw how levers work and were amazed to see the different weights that could be lifted depending on where the pivot point was.
