Mighty Machines (First Science Experiments S.) - Tapa blanda

Give kids a head start in science with simple experiments and activities that have been designed specifically for young scientists aged five to seven and which require only minimal supervision.

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.
