Gizmos & Gadgets: Creating Science Contraptions That Work (& Knowing Why) (Williamson Kids Can! Series)

I would have like clearer step-by-step illustrations or photos, as there are only some B & W ones, but I understand this might be geared towards teachers photocopying the material for class. The variety of activities is great. I'd suggest the age-range for 9-12 year olds to do by themselves. With kids 7 - 8 years old, you have to help them with most activities. I think most of these types of books tend to leave out physics pretty much, and this one includes lots of short explanations that go along with the activities, so that's a plus!

Both my boys (9 & 5) love this book!

Lots of fun things to make and I love that it gives all the reasons why they work. Great for summers of rainy/sick days. Only downside is you need materials that aren't always on hand for most of the projects but they're all fairly inexpensive and easy to get with some planning. Way better than most of the "busy" books I own.

I bought this for my ten year old son who is very smart, but not very interested in anything that seems like learning. He loved this book! He marked the book with sticky notes of what he wanted to make and started collecting the household items that you need for construction. He was bugging me to make stuff - definitely a great buy for kids that think science boring.

This book is so great. I have an 8 year old tinkerer who can use this book to make really cool engineering projects, some by himself! The paddle boat has been so fun to play with and he is quite proud of his success with it. Great book!

This was a Christmas gift for my 10 year old grandson. We have all enjoyed spending time with him reading this book and discussing which project to do next. Well worth the money.

We have tried several of the projects in this book and they have all worked on the first try. I run a summer camp and homeschool my kids and have looked at 100's of project books. This one is exceptional. The directions are clear, they appear to be "kid tested", and the science information is VERY well organized with several projects to illustrate each principal.

We love this book in our house! I pull it out when we are looking for something fun to do with the kids. My kids thumb through and pick out their favorite projects. It is fun and educational & a great addition to our homeschool book collection.
