What are levers


In school we are learning how toys work.

About cogs,levers and ramps.

There are three choices but i have chosen the lever because it makes work easy.

A lever is like a machine that does all the hard work.  It is used in different ways. Some of the way that it is used in is scissors,wheelbarrows, Bike brakes and also pillers. In class we made a lever that lifted a table. firstly we tried picking it up but it didn't work so we made a lever. The lever picked the table up. The lever was made from wood. After that we sat on the table and the lever still picked up. The lever is  helpful. In the future there should be more levers.

How toys work



Today we learnt one way that toys work. So I am going to tell you guys how toys work. You can push a toy or pull a toy with a string.

I have learned that toys can work by  pushing pulling. twisting, winding and with batteries.  

I chose  this colourful toy that works by winding. You wind that little yellow screw on the side. This toy is from McDonald. McDonalds is a fast food restaurant. This toy has a lot of cogs and gears inside of it. McDonald have a lot of good toys that I could choose, but I chose this toy. I like toys that have cogs in them because it is just like it has batteries in it. This toy works by winding and when you wind this toy there are a lot of cogs and gears inside of it that spin and make things move. When you wind this toy the McDonald sign spins. Wouldn't you like to learn how toys work as well?
