Sound Lesson 1 - What is sound?

Last updated about 5 years ago
17 questions
Note from the author:
This is part of a 6 lesson series adapted from OpenSciEd materials.

Pre-assessment - individual


Please complete the first four questions ON YOUR OWN as a warm up today. They do not have to be correct.
1

What quality of scientists do you want to focus on? Why did you choose that one?

observant, patient, good listeners, communicate well, persevere, hard working, detailed

Keep this in mind as you work through this GoFormative.

1

A large explosion can damage a person's hearing. What causes this damage?

1

When sound waves move through a medium, in what direction do the particles in the medium move?

1

What role does the inner ear play in hearing sounds?

Explore - with your group

Watch the video below. Work with your breakout group to answer questions 5-10. Watch is as many times as you need.

Focus on the video from 0:12-0:40
1

Watch the video and jot down your ideas.

Share your thinking as a group.

Record your responses HERE:

Initial model:

Draw and label a model that will help you explain your thoughts about this question: How does the sound coming from one thing (like the speaker) make another thing far away (like the window) move? For each location on your model, show a zoomed-in view of what is happening. Then, explain your model in words below.📷

Remember that a model tries to explain something that is too big or too small to see.
A model includes:
  • symbols
  • labels
  • colors
  • arrows
You can also draw this in your journal and take a picture here OR attach it in google classroom if you prefer. Please make sure I have access to this.

Connect

Each person gets two minutes to share their model. Take turns sharing your screen and listening to each other. Decide who will go first and decide a time keeper.

What does your model have in common with the others in your group? List the similarities and differences and record them below.

What is similar between your model and your peer’s model?

1

What is different between your model and your peer’s model?

What do you think it is most important to share back with the whole class about your models?

Apply - On your own

This is homework - to be finished after class

Build a small model of the truck and window at your house. Attached is the video that I made with a bowl, a speaker and a piece of saran wrap. You can build something like this too or a different version.

1) Build a model
2) Take a picture
3) Explain/label how it is similar to the video we watched in class (and at the top of this).

**If you have a video to share please attach it to this lesson on google classroom.


Here is my answer:


If you watch the video closely you can see the saran wrap move like the truck windows. TOO COOL!

Describe or list times you have seen a similar phenomenon with sound. For example, my husband was once watching Star Wars in the basement and he had the sound on so loud that the picture frame fell from the fireplace. It basically shook the picture off the mantle.

Feel free to take a picture OR attach a video to the google assignment in classroom.

Think about the following questions if they help you:
  • When or where have you seen sounds being made before? What was making those sounds?
  • When or where have you seen before a time where an object making sounds (the sound source) caused something to move or shake, like the window in the video?
  • When or where have you experienced a sound being received before? What objects have you seen receiving sounds besides the window in the video?
  • Have you ever experienced a sound going over a distance, like in the video?

Listen to the following mystery sound. What do you think it is?

Reflect


What is one question you are wondering after this exploration section? We will share these next class.

Getting Ready...


Next class you are going to need an instrument (recorder, guitar, harmonica, drum, bell, violin, trumpet) to share. Please find one in your home or make an improvised one (tin can and pencil). It is best if you can bring this to where you work and have it ready.

You are also going to need a ruler and tape handy during science.

The activity will work better with real instruments for us to use, but if you have a improvise you can do so (a tin can and pencil). We will share these so keep them handy.

Share with me what you are thinking right now for your science "meal" at the end of the year. Here is the menu for you to read.

At the very least, each of us will be creating a video to explain how sound works.

Here is a video explaining the MENU assignment again:



Watch the video and think about...
- who you want to work with?
- how much time do you want to put in outside of class?
- initial ideas that interest you?
- questions?
