Our second science topic this term is: SOUND!
Our learning objectives are:
To know how our ears work and how we hear sound.
To understand what is meant by vibration.
To know that sound travels in waves.
To know that sound waves travel in straight lines.
To know that a range of vibrations produce different sounds.
To recognise high and low pitch.
To know that the pitch of a sound is related to the size of vibrating part.
To start our topic, Mr Cooper came into school to talk to the children about our ears and how they work.
The children listened intently to what Mr Cooper had to say and asked some very tricky questions. The also learned some new science vocabulary they can use to label the parts of the ear. Such as:
Using these words, the children can explain how sound waves travel to the brain through the ear!
The second part of Mr Cooper's presentation was about deafness and about some of the problems people who have a hearing impairment experience.
He also taught the children how to 'finger-spell' using British Sign Language.
The children have been set a challenge: To finger spell their name in sign language.
Access these websites for further information and for activities about sound that children can do at home:
We will be doing more work on sound in the coming weeks and will add any new learning to the Wiki as it happens!
In the meantime children, let me know what you have found out in your independent learning by posting a comment.
IN SPACE, NO-ONE CAN HEAR YOU SCREAM!
This is the statement the children investigated today with the help of Mr Kinley.
From our learning this term, we know that space has no air so we set up an experiment to try to create a vacuum in the classroom.
This is a sound bell-jar. The pump at the bottom sucks out all the air from inside the jar.
The ringer could be heard from inside the jar but as the air was taken out, the ringer got quieter and quieter until it was almost impossible to hear it.
This proves that sound waves need air to travel and why...
...in space, no-one can hear you scream!!!!!
Mr Kinley showed the children how sound-waves move using a slinky!
Class 4/5, can you explain how sound-waves move through air using your new scientific vocabulary?
Using arm-dancing to show how sound-waves move!
Mr Kinley has some good moves!
Rhys' work show how well he understands how volume and pitch affects sound-waves.
Fab work Rhys!
Well done 4/5 for a fantastic learning afternoon! And extra thanks to Mr Kinley for coming into school to help us.
