Then we did some experiments to learn about levers and how they are used to do work.\u00a0 We learned that the longer the lever the less effort needed to lift a\u00a0heavy load but you can’t lift it very far.\u00a0 If you put the load on the long end and the effort on the short end you have to use a lot of force but you can lift the object higher.<\/p>\n

There are three kinds of levers, a first class lever, a second class lever and a third class lever.\u00a0 First class levers are the most efficient kind then second then third.<\/p>\n

We have been learning how castles were attacked and defended.\u00a0 Gatehouses made the entrance to the castle stronger.<\/p>\n

Drawbridges could be pulled up when under attack.\u00a0 \u00a0We made model gatehouses with working drawbridges.\u00a0 A drawbridge is a third class lever.<\/p>\n

Siege machines like the trebuchet were used to attack castles.\u00a0 We made model trebuchets.\u00a0 A trebuchet is a first class lever.<\/p>\n

Then we enjoyed testing our trebuchets.\u00a0 They worked really well!! A trebuchet is a first class lever.<\/p>\n

We did research on castles and made some super posters which are on our class wall.<\/p>\n
