Experiments!!!!

We've looked at all 3 classes of lever, and now we're getting PULLED into Pulley's!! (Pun intended!) Yesterday we braved the cold and wind and went out with a new problem for the students to solve. Lift a BIG HEAVY rock hold it up for at least 1 minute and you only get a rope. The students had lots of investigating and coming up with different ways of creating fixed pulleys. 

Here are a few snaps of the afternoon!

Making sure everything is secure...Safety first!

and HEAVE!!

It's not so heavy for some

Some groups only needed one person to pull!

Making it look easy boys!
