Simple Machines: Forces in Action (Do It Yourself)

I used this as a book for our simple machines unit for 3rd grade. It is simply written, has lots of pictures, and interesting activities that can be easily adapted for classroom experiments. Highly recommend.

good info for creating easy learning projects.

I used it to tutor a 4th grader - it's a great book, really engaging, lots of good vocabulary words.

Granddaughters found it interesting.and have made some machines themselves.
