Scientists and inventors found ways to bring electricity to the people who wanted and needed it. And, while we benefit from the discoveries that have already been made, there is always more to learn! Whether you try the activities in this book as a fun unit study, as part of your homeschool science lessons, as an extra project for school or a science fair, or just to discover new things, you’ll get an up-close look at electrical and magnetic forces. Enjoy the SHOCKING discoveries you make as you enjoy the PULL of science!
