Explores different aspects of simple machines and the physics that makes them work, and provides activities and experiments designed to teach children the basics of machines. - SterlingHow 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. Theyâll find out why they canât put in a screw using only their fingers and examine the different parts of compound machines. In another experiment, a childâs bicycle becomes a laboratory for understanding whether wheels have to be smooth to run. A good time will be had by all.
