Mighty Machines

First Science Experiments

by Shar Levine, Leslie Johnstone

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.

[Haylee Tappan · Rating 3 out of 5]

This book is great for those who want to start science experiments. All vocabulary words are bolded, and there is a table of contents so you can find information easily. It answers many questions about different phenomenon in kid-friendly language. It also explains all the materials you would need to do the experiments yourself.
