Learning comes alive when your students can actively apply what you've taught to their very real world experiences. Choose a general production category such as exercise equipment, infant toys, or school supplies for the whole classroom. Develop effective advertising for their product. An invention is a new discovery.
Inventions come about in many ways.
Usually, inventions happen because someone had to solve a problem. For example, an inventor once got tired of having cold ears in the winter, so he invented ear muffs. Sometimes inventions are the result of accidents. For example, a regular gas or electric oven is a good way to cook food. But the invention of the microwave oven made cooking much faster, and therefore it is an innovation in cooking.
