We Take School POs
All of our bargain books are brand new, perfectly readable and represent a tremendous value! The bargain books are, however, publisher overstocks and remainders that TRW purchases at deep discounts. As a result, they may have a small mark through the UPC bar code or a small mark on the side of the book. This is simply to mark the books so they cannot be sent back to a publisher. Because of this, bargain books are non returnable to TRW unless they are damaged. Please consider this before ordering.

Annotation: How do machines work? Kids will have a blast constructing a mini-seesaw to illustrate the way a lever operates or creating their very own pulley from an empty spool, string, ribbon, pails, pennies, a broom, and two chairs. They'll find out why they can't put in a screw using only their fingers and examine the different parts of compound machines. In another experiment, a child's bicycle becomes a laboratory for understanding whether wheels have to be smooth to run. A good time will be had by all.
