This week we are exploring ways to change the pitch of a sound.
LO To notice patterns between the pitch of a sound and the features of the object that produced it
Make changes to an object to alter the pitch of a sound
Make predictions about how the pitch will change
Draw a diagram of the object producing the sound
Explain how to change the pitch of different sounds
Click here for a video recapping the learning from last week and introducing the focus for this week.
Can you think of how we made this a fair test? What do you think would happen if we used different sized glasses?
Click here if you'd like to share your work with us - we'd love to see it!
Click here for a further explanation of pitch and an additional idea for the investigation if you have some plastic straws.
Click here for a further explanation of how a change in pitch is to do with the speed of vibrations.
This week we are continuing with our topic about sound. Today we are investigating how sounds are made.
LO To identify how sounds are made
I can remember to
find different ways of making a sound
identify what is vibrating to make a sound
use scientific vocabulary to explain
How is sound made?
If you put your fingers gently on your neck and hum you should be able to feel the vibrations. All sounds are made when objects vibrate. Sometimes you can see these vibrations. Click here to watch a video for some ideas of this. There's also some examples in the video link below.
Your task is to find and make different sound sources and complete a table to explain what the sound source is, describe the sound and explain how the sound is made. Click on the video for a demonstration of this. There are some other activities for you to try out including making a string telephone. The spoon and string one is my favourite! You don't have to do them all and you can think of your own too. You could have a go at creating your own instruments from recycled materials - try these suggestions. Don't forget to share you work here with us!
The Science of Sound 1
Freezing and Melting Science Activity
Check out this fun bit of science you can do at home. It's a great trick to try out on people! The instructions say to leave it for 10 minutes but we set the timer for 3 minutes and it worked really well. Click here to feedback or here to share what you do!
ELECTRICITY: Task 5
How is electricity made?
Electricity can be made using coal, gas, nuclear fuels, the wind or sunlight. Electricity is usually generated in large buildings known as power stations.
Watch the video below to learn more about how electricity is made.
ELECTRICITY: Task 4
Benjamin Franklin is credited for discovering electricity in the 1700s with his kite experiment in which he flew a kite with a metal key tied to it during a thunderstorm.
Electricity was first introduced into people’s homes near the end of the Victorian period in the late 19th century. The worlds first electric streetlights were setup in London in 1878 and can be found almost everywhere in the world today.
Watch this video to learn all about Benjamin Franklin. Then create a 'Factfile' about him. You can use the template below or create your own!
ELECTRICITY: Task 3
A circuit diagram is a pictorial representation of an electrical circuit with images used to represent different components in the circuit. An electronic circuit is comprised of electronic components, such as switches, bulbs and batteries all connected by a conductive wire which an electronic current can flow. Watch the video below to learn more.
ELECTRICITY: Task 2
Sources of Electricity
Read the PowerPoint below 'Exciting Electricity'.
Then, complete the task by sorting appliances into the venn diagram deciding if the appliance uses mains electricity, battery, both or neither.
ELECTRICITY: Task 1
Think about your whole day. From the moment you wake up, to the moment you go to sleep and every moment in between.
What do you need electricity for? When do you use it?
Record what items in your house uses electricity. You could record this as bullet points or labelled diagrams. Think carefully and record as acutely as you can.
I’ve started mine is there anything else you can add?
On this page I will be posting tasks for our Science topic: Electricity.
At school, we have lots of equipment we use for this topic however, we don't have access to this which means learning about electricity in a different way. We wont be able to cover everything but tasks might involve you doing some reading, getting creative (some writing links) or even investigating around your own home.
