The Cool Hot Rod and Other Electrifying Experiments on Energy and Matter (Exploratorium Science Snackbook) - Softcover

Inhaltsangabe

The experiments in this book are designed to call your attention to energy transformations and how they affect the world around you. Some of these experiments dramatically demonstrate how one form of energy can become another. For example, in "Stripped Down Motor", the energy of an electric current is transformed into movement. This very simple motor relies on the same principles as the electric motors that power fans, blenders, washing machines, and other electrical appliances. This text contains 22 experiments for teachers, parents and students to do at home or in the classroom. The experiments are easy to perform and are illuminated with line drawings, photographs and sidebars. The experiments explore magnetic fields, electric currents, the effect of heat and cold on the size of objects, how clouds form, how molecules behave and much more.
