Eleventh graders explore the electromagnetic spectrum — the full range of light, from radio waves to gamma rays — discovering that they’re all the same phenomenon differing only in wavelength and energy, and each has unique uses.
Students will be able to…
Radio, microwaves, visible light, and X-rays seem completely different — yet they’re all the SAME thing: electromagnetic waves. What makes them different, and why is each one useful?
Project this and match each part of the electromagnetic spectrum to its property or use — tap a band, then tap its property.
Tap any phase to open the teacher moves and student actions.
Radio, light, and X-rays seem different — but they’re all the same. How?
Students investigate.

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students explain why high-energy waves (UV, X-rays, gamma) can be harmful while lower-energy waves (radio, microwaves) generally are not. A printable EM-spectrum sheet is in the Science library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
