When they were all ready, we had a competition to see which one was the fastest. Who can think of another event for our cotton reel tractors? We will continue the competition next week. Who has plans to change their tractor design?
Mmm... that seems to run smoothly now. I wonder if I need a longer lever.
Today we had our second input/ output challenge. We worked in pairs to make a cotton reel tractor. It was quite tricky to get the tractor to run smoothly.

I wonder how you made them.
WOW Josh
It was really hard to make them but I like doing them.

Hi there Room 9 Tractor Fans.
I have three questions for you:
-Does anyone think their tractor could go up a gentle slope?
-Could you see which tractor went in the straightest line?
-What about finding two fat elastic bands for tyres for your tractor? What would that do?
Have fun on Friday.
And Brooke, I was really glad that you kept trying, even when it was hard to do. Those elastic bands are SOOO tricky to thread through the hole, aren't they?
