DT - simple machines ⚙️

This afternoon, we explored a range of mechanisms in models or products. 

Simple machines make physical jobs easier by changing the direction or force. We looked at six simple machines: pulley, lever, wheel and axel, wedge, inclined plane and screw. 

To further our understanding, we discussed combining these simple machines to make complex compound machines for example a wheelbarrow which would use a lever with a wheel and axel. 

Using their knowledge, the children then went on to design and create their own version of a simple machine using a range of junk modelling materials.
