Somehow, GR merged my comments on two different books.
Hardware Store:
Organized by various physics principles, mostly simple machines. Each section describes a the ways that the principle can be found in a hardware store, with a few simple activities.
Housewares Store:
Mostly describes phyics in everyday appliances, with an emphasis on simple machines and heat.
What a great book that my middle schoolers will love.....all the things that they can find the garage. How the science applies to the function of the tool!!!
I love this book and plan on using it when I teach my Force & Motion unit next year.
