Switch On, Switch Off (Let's-Read-and-Find-Out Science 2)

The book is awesome. My only problem is that a I received a notorious used one instead of new.

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.

Used this is teaching a college level class for future teachers and it was a hit. Great!

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.

Really nice illustrations and explanation of how electricity is generated and sent along a circuit. Even I learned something! I like that the story line centers around turning the light out and going to bed - makes it a nice bed time story for five year old curious about electricity. A little above reading level of most five year olds, but still teaches to topic very well if read by adult.

I agree with the other reviewer - where is a discussion of safety? Like don't put anything in a plug/socket and don't touch the prongs etc.

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.

My 4.5 yr. old grandson told me that he wanted to know all about electricity and this book fit the bill for that/makes it fun learning and doing!!Excellent book even for a young lil' guy wanting to know about electricity!

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。
