Science

This term we are going to be looking at 'Sound'. You will be looking at: What sound is and understanding sound waves. You will have four tasks to complete during this week. Please watch the PowerPoints and videos first and then complete any worksheets neatly ino you book. If you have any question about the tasks, please email me.

Task 1

What happens to sound when we get further away from it?

I would like you to go into your garden and close your eyes. Listen to the different sounds you can hear. Complete the table below into your book.

You can do this task with your adult or any family member. 

Now watch the short video clip below to explain how distance affects sound.

Now I would like you to set up a simple investigation to answer today's question - What happens to sound when we get further away from it?. 

Things to think about:

Think about what you are going to change? (distance from the sound)

What are you observing? 

What are you going to keep the same? 

How are you going to present your results? 

Steps:

1) Make a sound. How are you going to do this? You could go into your garden and bounce a ball or hit a pan with a metal spoon?

2) You need to 'score' your sounds. How will you do this? You can rank the sounds or give a score out of 10 fo each sound.

3) You need to present your results. Could you draw a table?

Take a look at the diagram below. You can present your task any way that you wish. 

Task 2

What is sound?

In this task you will understand that sound is caused by vibrations. This is a movement backwards and forwards. Place your finger tips against your throat as you speak. What can you feel? Now watch the video link below.

Sound is made by something vibrating. Look at the simple experiments below and have a go at making sound.

Complete the experiments with your adult and record your findings into your book. You can write a paragraph or draw a picture to show what happening in each activity. Have fun!

Activities to make sound:

1. Place some rice on a piece of paper. Hold this paper a small distance above a metal pan that has been struck.
2. Hang a metal coat hanger upside down. Tie a piece of string from each of the two corners and place each one on ear. Someone else strikes the coat hanger.
3. Hit a spoon on a table and then place into a bowl of water.
4. Hang a table tennis ball from a length of string. Touch the ball with a vibrating spoon.

Task 3

Where does sound go when it has been made?

In this task you will understand what happens to the sound once it has been made. You will learn that sound can travel and reaches our ears, so we can hear it.  Click on the link below and watch the video.

Sound is caused by vibration. Vibration means wobbling back and forth. When you pluck a guitar string you can see the string vibrating. This is caused by the air touching the string to vibrate, which causes air further away to vibrate. The moving vibraton is called sound wave and the brain experiences a sound!

Your task now is to order the pictures and the description into the correct order to create an explanation text. Stick these into your book. Click on the link below to access your worksheet.

Task 4

This week you have been introduced to many new key words and knowledge about sound and how it travels. Your task today will be to recap and learn the meaning of the key vocabulary and to understand the key knowledge facts you have been introduced to. One you have done this, have a go at the quiz below.
