Step-by-step solution for: How sound travels | 5th grade Science Worksheet | GreatSchools
It looks like you've uploaded a page from an educational resource titled "Sound can be speedy" by Carling Kuchera, published in 2013. This is a science activity designed for students to explore how sound travels through different materials, particularly solids, liquids, and gases.
Since I cannot view images directly, I will provide a detailed explanation based on the text visible in your description. If you'd like me to analyze specific parts of the image or clarify any section, please describe it further.

#### 📌 Background Knowledge:
- Sound travels fastest through solids, then liquids, and slowest through gases.
- This happens because particles are closer together in solids (e.g., metal), allowing vibrations to pass quickly.
- In gases (like air), particles are far apart, so sound travels more slowly.
- The vibrations travel through the solid material (e.g., a string) faster than through air, which is why you can hear sounds better through solids.
> Example: A child tapping one end of a metal rod will produce a sound that travels quickly through the rod — faster than through the air.

#### 🧪 Objective:
To demonstrate how sound travels through solids (specifically, a string) compared to air.
#### 🔧 Materials Needed:
- Two paper cups
- A long piece of string (about 5–6 meters)
- A pair of scissors (to cut the string)
- Optional: A ruler or tape measure
#### 🛠️ Instructions:
1. Prepare the Cups:
- Poke a small hole in the bottom of each cup.
- Thread the string through both holes.
- Tie a knot at the end of the string inside each cup to keep it secure.
- Make sure the string is taut (tight) when pulled between the two cups.
2. Set Up the Experiment:
- Have two students stand several meters apart.
- Each student holds one cup.
- Pull the string tight so there’s no slack.
3. Test the Sound Transmission:
- One student speaks into their cup while the other listens with their cup held to their ear.
- Try speaking softly and loudly.
- Then, try talking without the string being taut (loose).
- Compare the clarity of the sound in both cases.
4. Repeat the Test:
- Try using different materials (e.g., cotton thread, wool, wire) instead of string.
- Observe how well sound travels through each.

The worksheet includes questions for students to answer after conducting the experiment:
1. Take notes now – can an adult or superhero hear?
- *Purpose:* Encourage observation and reflection.
- Students should note whether they could hear clearly through the string vs. through the air.
- They may observe that the sound was clearer and louder when the string was taut.
2. Make a table – what will work best?
- Students test different materials (string, wool, wire, etc.) and record:
- Material used
- Clarity of sound
- Volume heard
- Whether the string was taut or loose
3. What do you think would happen if the string was not tight?
- Answer: If the string is loose, the vibrations won’t travel efficiently — the sound will be weak or inaudible.
- Explanation: Loose strings allow energy to dissipate; tight strings transmit vibrations better.
4. Why does sound travel faster through solids than through air?
- Because particles in solids are closer together, so vibrations pass from particle to particle more quickly.
- In air, particles are farther apart, so vibrations take longer to move.
5. Can you think of a real-life example where this principle applies?
- Examples:
- Hearing footsteps on a wooden floor.
- Listening for animals through the ground (e.g., elephants sensing vibrations).
- Using a "tin can phone" (a classic demonstration of sound through solids).

- Sound as vibration
- Mediums of sound transmission: solid > liquid > gas
- Importance of particle density
- Practical application of physics principles
---
This hands-on activity helps students understand that sound travels faster and more clearly through solids than through air, due to the close proximity of particles in solids. By building a simple "string telephone," students experience firsthand how vibrations transfer through a solid medium.
