🔍 Task Overview

The worksheet has two main parts:

1. Observations: A brief explanation that when you hit, shake, or scrape things (like strings, a flute, or a drum), they make sounds — this is because vibration creates sound.
2. Science Activity: Students are asked to draw a circle around each instrument that makes a sound when you hit it.
3. Science Exploration: A follow-up question asking what happens when you hit a drum with your hand and then with a stick — and how the sound changes.

✔ Step 1: Identify Instruments That Make Sound When Hit

We need to look at the instruments shown in the picture and determine which ones produce sound when hit.

Here are the instruments depicted:

1. Maracas – Shaken, not hit → ✘
2. Trumpet – Blown into → ✘
3. Violin – Played with a bow or plucked → ✘
4. Triangle – Struck with a metal beater → ✔ (Hit)
5. Flute – Blown into → ✘
6. Drum – Hit with hands or sticks → ✔ (Hit)

So, the instruments that make sound when hit are:
- Triangle
- Drum

✔ You should draw a circle around the triangle and the drum.

🧪 Step 2: Science Exploration Question

> "How was the sound of the drum different when you hit it with your hand and then with a stick?"

#### Explanation:
When you hit a drum with your hand, the sound is usually:
- Softer
- Warmer tone
- More muffled

When you hit it with a stick, the sound is:
- Louder
- Sharper
- More focused or crisp

👉 This is because different materials and shapes transfer energy differently. The stick is harder and more rigid, so it transfers more energy quickly, creating a louder, sharper sound.

#### Answer:
> The sound was louder and sharper when I hit the drum with a stick, but softer and deeper when I used my hand.

✔ Final Answer Summary

Instruments to circle (that make sound when hit):
- ☐ Triangle
- ☐ Drum

Science Exploration Answer:
> The sound was louder and sharper with the stick, and softer and deeper with the hand, because different materials create different vibrations.
