Sometimes prices go up and up and up. Then they suddenly crash. Why? In simple language and with colorful graphics and amusing characters, this picture book explains the basic laws of supply and demand, using examples kids will understand, such as dueling lemonade stands on the same block. Terms such as "fixed costs" and "variable costs" are clearly explained, and a glossary as well as a helpful graphic summary are included.

Patterns are fascinating! They can be so beautiful that people come from all over the world to see them, or so familiar you hardly notice them. They appear everywhere: beehives, dinner plates, even the bottoms of your shoes!
With stunning photographs that show diverse examples from nature and artwork around the world, Bruce Goldstone reveals the secrets behind patterns--and gives you some fun ideas for making your own.
