Electricity: Investigating the Presence and Flow of Electric Charge
The quest to understand how electricity works has led to some of the most important discoveries and inventions of all time. Scientists have figured out how to harness the power of electricity on a very large scale in massive power plants and on a very tiny scale in computer circuits. This book includes geniuses, like Benjamin Franklin, Nikola Tesla, and Thomas Edison. Our modern ideas have been assembled over a long period as scientists built upon the work of their predecessors. This book reveals what we have learned in the past, what we have discovered in the present, and what remains to be explored in the future. Supplemental content includes an activity spread, a substantial and highly detailed timeline, and a list of key people with mini-biographies.
