Simple Machines: Screws

Today LZ3 looked at a simple machine called screw. First Mrs Lal showed us a bag with lots of screws, a screwdriver and a cork opener. Next we read a book about screws. We learnt that screws hold things together. Finally we looked around the class for things with screws. We also took pictures of them. We really enjoyed learning about screws in our class.
