more levers

The y4's made even more complex mechanisms today where levers move in opposite directions.

This example shows that when you pull the leg the duck 'quacks'! Quite understandably in my opinion.

today

Today in Y1 we painted the clay fish. We might give them a coat of PVA when they're fully dry just to give them a bit of protection/shine. They will be mounted in under sea dioramas eventually - more of which anon.

 

 

In Y4 we completed our paper engineering - lever mechanism pieces. This one, when the lever is pulled/pushed, operates and moves all 3 oars simultaneously. Next week we're moving on to cams!
