My daughter has been tasked with building a model size compound machine. Two simple machines working together to perform a task. Creativity is NOT my specialty. Any suggestions?

Thats okay, its her assignment! Now, what is _your_ home work for the day?

My daughter will do the work with assistance from me. There is no harm in getting ideas from others, in fact her instruction sheet encourages it.

2 pencils, 10 popsicle sticks and a bunch of butterfly clips?

It's called a polygraph. (Not the lie detector.)
 You use it to write/draw the same thing on two pieces of paper at the same time. A compound machine combines multiple simple machines to make one device. In this case, you have several levers and axles working together. 'One of the neatest compound machines a kid can make in 5 minutes.

Late edit: I wrote "several levers and axles working together," but that should have been "several fulcrums and levers at work."
