Tap to Learn the Meanings!
- ears: The parts of our body that help us hear sounds.
- electricity: A type of energy that powers many machines and devices.
- hear: To notice sounds using your ears.
- list: A group of words or ideas written one after another.
- results: What we find out after doing a test or investigation.
- scientists: People who ask questions and learn by doing experiments.
- sound: Something we can hear, made by vibrations.
- source: The place or thing where something comes from.
Well done for learning new science words!
What Is a Sound Source?
A thing that makes a sound is called a sound source.
Sounds That Use Electricity
Some sound sources use electricity.
How We Hear
We hear sounds with our ears.
Sound Sources in a Picture
Look carefully at the scene and use it to answer two questions:
- Count the sound sources in this picture.
- Name the sound sources that use electricity.
Think Like a Scientist: Find That Sound!
You will need: Some sound sources, a blindfold.
Scientists are people who do investigations to answer questions. What you find out is called your results.
We will try to answer this question:
Can a friend point to sounds you make?
What to do:
- The children investigate to see if Zara can point to the sound.
- Talk to your friends about doing this investigation.
- Plan which sound sources you will use.
- Predict which things they can point to.
- Write your prediction and results like this.
Can a friend point to these sounds?
| sound source | prediction | results |
|---|---|---|
| clock | yes | yes |
Do the investigation with your friends.
Which sounds were easy to find?
How am I doing?
Were some of your predictions wrong?
When predictions are wrong, it shows we have learnt something new.
Great work! You planned carefully, tested your ideas, and learned from your results like a real scientist.
