levers

Today, by the request of the kids, we got out this book again...
The New Way Things Work

So we could work on the next unit... Levers...

I even had the DVD already checked out from the library.

We also got out this kit as well...K'NEX EDUCATION Intro to Simple Machines: Levers and Pulleys-178 pcs

First we read the intro out of the book and then watched the DVD. After that the kids started to work on building the see-saw....
Once it was built... the mini figs went for a ride :-)
and then they did the experiments from the teachers' guide...
They moved the load and the fulcrum to see how the amount of force needed to do the work changed. Then they just "played" with it for quite a while... mostly using it as a balance.

This kit has a ton of different levers to build. The kids can't wait to move on to the next lever.... I think it's another first class lever, a balance scale, I think. I love how this little study we're doing using The Way Things Work book has really taken off with both kids. Alex had already read a lot of the book... but between the kits and the movies, things are really sinking in for him!
