    THOMAS ALVA EDISONSCIENCE EDUCATION SERIES

    Science is a way of knowing about, understanding, inter-acting with, and appreciating the world around us. Sciencelearning begins by probing, questioning, and discoveringthe wonders of the world in which we live.

    The Thomas Alva Edison Science Education Series usesa hands-on, minds-on approach to help students use

    knowledge and skills obtained through activity-centered ex-periences to understand the past, present, and the futuresources and uses of energy within the natural and socialsystems of our environment.

    This Science Education Series will strengthen any scienceprogram by providing students with current information

    about science exploration and discovery. By developing anunderstanding of how persons relate to natural systems, theEdison Science Education Series will help students to dis-cover how they can become energy literate and be effec-tive managers of the natural environment in which they

    live.
