The radiant energy from the sun gives us the amazing electromagnetic spectrum. It doesn't matter whether we can hear them or see them, they are all around us! From the longest wave lengths to the shortest, your students will learn about all of the important parts of the EM and our uses for each in today's world. Take an up close look and learn about each part together with this power point. Teachers, you will want to make sure your students have a copy of the EM before starting so they can refer to it as you progress through the lesson.
