Warm-Up: What Makes Sound? (5 minutes)

Teacher: Good morning, everyone! Today, we're going on an adventure to discover the secret of sound.

(Display Vibration Station Slide Deck - Slide 1)

Teacher: Can anyone tell me, what is sound? How do we hear things?

(Allow students to share their ideas. Guide them to think about how sounds are made.)

Teacher: That's right! We hear sounds all around us, like music, talking, or a bird singing. But what actually makes the sound? What happens when something makes noise?

Introducing Vibrations (10 minutes)

Teacher: Let me show you a secret!

(Display Vibration Station Slide Deck - Slide 2)

Teacher: Look at this rubber band. What do you think will happen if I pluck it?

(Pluck the rubber band. Ask students what they observed.)

Teacher: Did you see it move? Did you hear a sound?

Teacher: That quick back-and-forth movement is called a vibration. Say it with me: Vibration! When something vibrates, it wiggles very, very fast. And guess what? These wiggles make sound!

(Display Vibration Station Slide Deck - Slide 3)

Teacher: So, vibrations are like tiny, fast wiggles. When an object wiggles, it pushes the air around it, and those air wiggles travel to our ears, and our brain hears it as sound! It's like tiny waves of sound travel to us.

Teacher: Try this: gently put your hand on your throat and make a humming sound. Can you feel anything?

(Give students time to try this.)

Teacher: What do you feel? (Hopefully, they say vibrations!) Yes, your vocal cords are vibrating to make your voice!

Vibration Exploration Activity (15 minutes)

Teacher: Now it's your turn to be a sound scientist!

(Display Vibration Station Slide Deck - Slide 4)

Teacher: We are going to explore different objects and try to feel and hear their vibrations. I've got some special objects for us today.

(Distribute the materials for the Vibration Exploration Activity. Go over each station or object and provide instructions.)

Teacher:

• Ruler: Place a ruler on your desk so most of it hangs off. Hold one end down firmly and pluck the free end. What do you see? What do you feel? What do you hear?
• Drum with Rice: Gently tap the plastic wrap drum with rice on top. What happens to the rice? What does that tell you about the plastic wrap?
  

(Circulate around the room, guiding students and asking questions about their observations. Emphasize feeling the vibration.)

Connecting Vibrations to Sound (10 minutes)

Teacher: Alright, sound scientists, let's bring it back together! What amazing things did you discover during our activity?

(Call on a few students to share their observations. Encourage them to use the word 'vibration'.)

Teacher: So, what did we learn today? What is the big secret of sound?

(Display Vibration Station Slide Deck - Slide 5)

Teacher: You got it! All sounds are made by vibrations!

Teacher: Now, to show what you've learned, I have a special worksheet for you. On this Sound Vibration Worksheet, I want you to draw two objects that make sound. Then, I want you to show or tell how they vibrate to make that sound.

(Distribute the Sound Vibration Worksheet. Give students about 5 minutes to work on it.)

Cool Down & Share (5 minutes)

Teacher: Great work, everyone! Before we finish, I have one more quick question for you.

(Distribute the What's That Vibration? Cool Down.)

Teacher: Please complete this quick cool-down activity. When you are done, you can turn it in. If you have time, think about what was your favorite vibrating object you explored today and why.

(Collect the cool-down slips.)

Teacher: Does anyone want to share one thing they learned about vibrations and sound today?

(Allow a few students to share.)

Teacher: Excellent job today, sound scientists! You now know the secret of sound!

Vibration Exploration Activity

Welcome to the Vibration Station! Today, you are a sound scientist. Your job is to explore different objects and find out how they make sound.

Station 1: The Wobbly Ruler

1. Place a ruler on your desk so that about half of it hangs off the edge.
2. Hold down the part of the ruler on the desk very, very firmly with one hand.
3. With your other hand, gently pluck the part of the ruler that is hanging off.

Observe and Discuss:

• What do you see the ruler doing? (Look very closely!)
  
  
  
  
• What do you feel when you touch the wobbly part of the ruler? (Be careful not to stop the movement!)
  
  
  
  
• What do you hear?
  
  
  
  

Station 2: The Rice Drum

1. You have a small container with plastic wrap stretched tightly over the top, and some rice grains on the plastic wrap.
2. Gently tap the side of the container (not the plastic wrap directly).

Observe and Discuss:

• What happens to the rice grains when you tap the container?
  
  
  
  
• What does this tell you about the plastic wrap? Is it moving?
  
  
  
  
• What do you hear when you tap the container?
  
  
  
  

Station 3: Your Own Voice Box!

1. Gently place your fingers on the front of your throat.
2. Make a sound, like humming or saying "Ahhhhhh."

Observe and Discuss:

• What do you feel on your throat when you make a sound?
  
  
  
  
• What happens when you stop making a sound?
  
  
  
  
• What does this tell you about your voice when you speak?

The Secret of Sound!

We learned that all sounds are made by vibrations! Vibrations are super-fast wiggles.

Draw and Write:

1. Draw an object that makes a sound. Show or tell how it vibrates to make that sound.
   
   
   
   
   
   
   
   
   
   
   
   
   

2. Draw another object that makes a sound. Show or tell how it vibrates to make that sound.
