Science Lab in the Supermarket

From the Introduction You probably don't think of a supermarket as a science laboratory. After all, you go to a supermarket to buy food, cleaning supplies, or paper products-not to conduct experiments. The truth is every aisle, shelf, nook, and cranny of a supermarket could be the source of a scientific wonder. Allyou have to do is take the time to look around and use your imagination. Items found in the produce aisle can teach you about biology. The aisle with cleaning products offers all kinds of lessons in chemistry. The dairy isle can teach you something about science too. "Wherever you look, you can study the sciences. The order and location of the aisles and the arrangement of the shelves have all been carefully designed to get customers to buy as much as possible. The strategies used by supermarket designers are based on the science of psychology, which looks at the behavior of human beings. Scattered throughout this book you will find a safety symbol. Ask an adult to help you whenever you see this symbol. The symbol indicates that an experiment is a little bit dangerous or difficult. I'd hate to see you get discouraged or hurt while you are learning about science in a supermarket.
