How can we hear so many different sounds from across the room when we spin the record?
- Do Now- Copy down today’s homework assignment in your planner. Get out your ISN and open to page 17. Read your observations of the sound device on page 17.
- Initial Model/Explanation- How does the sound come from the needle and the record? How did all of those patterns that we observe happen? How can we hear all these different sounds from across a room? On the handout, draw your ideas of what you think is happening where the needle touches the record, and what is happening in the air between the sound source and your ear that would really help show and explain, how is it possible we can hear all these different sounds coming from the device?
- Consensus Circle– Review discussion & circle norms. Bring your models to the circle. Show your model and explain all the elements of the model. As a class, find similarities and differences and record these. If something is repeated several times, that is important!
ISN p.16- Write 2 questions you have related to sound and how we hear different noises.
