Tides - Modeling Periodic Phenomena

Here is a series of lessons about tides that I used as an introduction to sine and cosine curves after I taught a unit on circular motion (they used sine and cosine as parametric equations to model circles before seeing the waves).

Feedback is welcome.

Whoa, a whole series… nice! I’d love to take a look.

Let me know what you think! I made a few edits after using these with students – mostly reordering slides and redacting a few slides. But I am definitely open to feedback!
