Switch On, Switch Off

Really great book! It's simple yet very informative. My two year old loves it as he is very interested in how lights work so this was perfect. Refreshed a few things for me too! Absolutely recommend this book!

もうすぐ四歳になる子にかいましたが　ちょっと内容が難しかったです。でもこの内容が理解できる年齢の子にだったら　すごくわかりやすい科学に基づいた本だと思います。

No discussion about safety. Any children's book on electricity should really talk about that component, too. Otherwise, great information and embedded instructions for an experiment were nice, too, but a little advanced for the youngest readers.

I love this book it explains in the simplest terms how electricity makes things go on and off.It starts by telling you that when you flip a switch the lights go on and when you flip it down the lights go off, 'it is like magic' the book says but then goes on to say however it is not magic it is electricity and then the whole explanation begins.Various electrical energy used around the house is explained. There is also a simple experiment where you get to generate some electrical energy using a compass, a magnet and some wire. It explains how electricity comes from the generators to your house and how they light up your home.My son love these books.

Switch On, Switch Off (Let's-Read-and-Find-Out Science 2) Another great book in this series. Teaches kids how electricity comes into your home. There are schematics showing simple wiring thru a house. It explains about the circuit and what happens when there is a broken circuits. Switching off and on is breaking the circuit. For a few days after our first reading of this book we had lots of appliances switching off and on, you know scientific experiments! Another one of those things in life we take for granted. This book helps kids become aware of electricity and how it works. Great. Switch On, Switch Off (Let's-Read-and-Find-Out Science 2)
