Big Idea

Today, we’re going to explore how a little trigonometry can help us create beautiful oscillations and rhythms.

Lesson Takeaways

Mathematical:

1. Sine waves
2. Amplitude
3. Angular Frequency
4. Period

Computationally:

1. Wait
2. Erase

Intro Questions

1. What are some things in life that are repetitive?
2. What are some things in life that goes back-and-forth?
3. What are some things in life that are constantly returns to its original point?

If you have all 3 of these things, it’s called an oscillation!

Oscillation is the repetitive back-and-forth motion of a system around a central equilibrium point.

Activity 1: Spiral

A great place to start exploring oscillations is with the spirals we’ve create in the past.

Let’s start by making a spiral of your choice.
