TV Remotes

Can you imagine having to actually get up to change the channel on your TV? Well, before the remote control was invented, that's exactly what you had to do. A remote control can actually turn your lights on and off, change the temperature in a room, and even lock your doors! But, be sure not to lose it or YOU might actually have to get up and do it for yourself! This book will allow students to ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other.
