Dear Bloggers,

The last few days have been quite warm but 2AF knew how to cool themselves down.  They had to design and make a fan that: used gears or pulleys, moved a large amount of air and was stable.  Lots of experimenting and design modifications occurred but by the end of the lesson all students had a wonderful fan.  The secret: large propeller blades to move lots of air, a broad flat base for stability and a large driver gear with a small follower gear so that the blades move as fast as possible.  It was a breeze really!!! (pardon the pun – I couldn’t resist).

 

Thanks for calling by

Mrs Garlick
