Lovely Levers!

On Monday 2nd February, Mr Davies, the Living History teacher from King Edward's School, came to visit Year 5.  This half term, Year 5's Science is to know about levers, and history is all about the Egyptians, so Mr Davies taught us all about how levers were used in Ancient Egypt and in other periods of history.  We also learnt how levers are still used today....

Shadufs

We learnt how the Egyptians used a special kind of lever called a 'Shaduf' to lift water from the Nile and transport it to the fiels to water their crops.  The lever made the water feel much lighter than it actually was and made it much easier to lift.......

Drawbridge

Mr Davies demonstrated how a drawbridge worked by getting some of us to put together a model of one.  In a drawbridge, levers are used to raise the bridge if enemies attack...

Trebuchet

A trebuchet was used as a weapon in the olden days.  It uses the principle of levers to fling things through the air, so mind your heads!

Take a look at these clips to see how the distance from the pivot affects the load and effort needed....

Levers today

We looked at all the different ways which levers are used today....

Back in class, we had a go at making our own simple levers to test how the distance from the pivot point effects the amount of effort that is needed to lift an object.....

When I tried to lift the bag up on the end, I found it very hard! I really enjoyed learning about levers and about The Shaduf. I really liked today!
