This term we are learning how people earn a living,And year 3's and 4's have been doing sound.We made a tellephone!!!!!!!!

The gunners

WALT find information
We are looking at sound
1. Things that vibrate or move backwards and forwards very quickly make a sound
2. Elastic bands and rulers are sources of sound
3. Often we can't see vibrations because they are so fast but we can still hear the sounds
4. Sources of sound are all around us

Brainiacs

WALT find information
We found information on sound

1. Beating a drum hard causes louder vibration and louder sound
2. Sounds are louder closer to the sound source
3. A small vibration means a quiet noise
4. The harder the blow the bigger the vibration is and amplitude
5. The amplitude of a sound wave tells us how big the vibrations are

WALT find information

We found information on sound

1. Sound can travel through different materials
2. When sound is going fast it makes a high noise/pitch
3. When sound is going slow it makes a low sound
4. Sound is a noise which is made by vibrations
5. Sound can travel sideways not upways

Brain Busters

These are the things we have learnt about sound

1. Sound can travel through different materials
2. Sound is made when something vibrates
3. The outer ear is called the pinna
4. The outer ear also includes the ear canal
5. The Malleus which is attached to the eardrum and means hammer in latin

blog busters sound

We learnt that: incetcs make a buzzing sound beacause their wings are beating very fast.Did you know that the harder you hit something the louder it is and the louder the noise and the longer it lasts the more dangerous it is for your ears.Also we can mesaure sound waves by counting the number of vibrations that occur per second.If somting is going slow makes a deeper sound and if something is going quikly then it will make a high pitched noise.

sound by kiana and grace

we are lerning about sound
-sound gets quiter the ferther you move away from the source. (stero)
-sound waves get louder as it travels away from the source
-the longer the string,the lower pitch.
-a high frequecys a higher pitch.
-sound travels faster through a vacum.

dx,sound.

1.Sound can go through diffrent matireals. 2.There is no sound in space because of the vacum. 3.Vibrations can travel through air. 4.sound can get quiter the futher away it goes. 5.the faster the vibration goes make higher sound.

Amazing bloggers

today we learnt
vibrations travel thew air.
sound travels thew diffrent merterls.
you can't hear stuff in space.
the number of vibrations is called the frequency.
when a peace of sting is vibrating you can change the pitch by changing the length.
by H.G,G.O and K.S

sound

WE LEART:
-sound waves help make sound , the bigger the wave the louder the sound and smaller the smaller the sound smaller the sound
-all things that vibrate make sound
-vibrating air is what makes sound
-the loundness of of sound is mesuerd in deuibels

HAJ company

Today the HAJ company knew that Vacuum means that their is no sound in space. Things that vibrate moves, backwards and then forwards quickly. Insects make a loud buzzing sound because their wings flap quickly. Also sound can be hear outside.

Sound - a message from Mrs Waterland

Should any of you check the blog at the weekend it would be very handy if you could bring an empty plastic bottle (like a lemonade bottle or a milk one)to school. It needs to be either a 1.5 l or a 2 l one.
Hope everyone is having a lovely weekend
Mrs Waterland
