Learning Goal: Use computational and mathematical thinking to describe the action and characteristics of waves. Specifically, we are deriving the relationship between velocity, wavelength and frequency. 1. Gather and check you have everything, including units on your Making Waves Handout. Check in with your group and see who has questions the group can answer. 2. Class discussion - groups add their data to the class spreadsheet and we look for patterns. Discuss how we made the waves and the relationship specifically between frequency and wavelength. What if we had kept time constant when making the waves? Velocity remains constant even when the frequency changes. velocity only changes if the medium changes (substance or temperature the wave is going through is different). 3. How do we use algebra to figure out the different characteristics of a wave given the relationships? We watched a short video about using dimensional analysis to solve conversion problems and physics and measurement problems. 4. Individuals work on their Wave Equations worksheet. Students who are figuring it out, will become tutors to help students still figuring it out. Make sure you can do the problems yourself. Friday: 1. Do Now: review waves on a Kahoot!. If you were gone today, please play the Sound Waves Kahoot! at home. Game PIN: 06863734 Continue working on your Wave Equation WS If time, we will play the Kahoot again or a new one.
