A complete Waves unit for grades 9–12 physics — wave properties, velocity, interference, sound, and the electromagnetic spectrum through slide decks, warm-ups, assignments, an exploration activity, a crossword review, and a unit test. Answer keys included; aligned to NGSS HS-PS4-1, HS-PS4-3, and HS-PS4-5.
Which one do I need? The Waves Unit Bundle collects everything on this page in one download for less than buying the pieces separately. The Final Frequency escape room closes the year — it is Case 8 of 8 in the series.
