Simple Machines Unit

We did a fun 2 week long simple machines unit that I put together using books from our library and simple machine projects I found from around the web. The first day we did an overview of all the different simple machines. Then each day we chose a different machine to learn about. Then we had a review day, followed by a compound machine day. And we finished it up by creating our own compound machines.

Here are some highlights.

We learned why a wedge is so helpful by trying to hammer a bolt vs. a nail. PA220031

We had a pulley tug of war.  Two people vs. one.  It was neat to see Katey overpower both the older kids.

She used our catapult and made a pulley system to move the bowl as well as a wheel and axle.

Tommy made a quite complex bird feeder.

This was such a fun unit for us.

Most, if not all, resources that we used can be found on my Prairie Primer Pinterest Board.

I'm totally impressed! What a great hands-on unit! I'm sure they learned a tremendous amount.
