I have lernt what sound is now. I love our sound topic.

# data[].attributes.body
I have learnt that  when  sound travels it creates sound waves and that scientists use Infra-sound to track volcanic eruptions.

# data[].attributes.body
I have have learnt how sound can vibra makes a tinkling nose

# data[].attributes.body
I learnt that sound travels in waves.And if you put your head on the ground you can hear it

# data[].attributes.body
I have learnt that sound can make lots of different types of noises and that different things make different sounds. Sound can be very quiet and very loud. Sound can be very powerful even if it isn't that loud

# data[].attributes.body
I have learnt that sound travels through vibration

# data[].attributes.body
I learnt that sound sound travels better under water and I also learnt that sound travels at all different speeds.

# data[].attributes.body
In our class we have learnt about sound and how it is made. We did a sound investigation

# data[].attributes.body
I have learn't that sound there are NO sound in space but under water sound sounds better than above. I have also learn't about how many noises one balloon can make and how different it sounds.And if you use a tuning fork on different materials it might sound different

# data[].attributes.body
I have learnt about all the different types of sound.I have also learnt how sound travels

# data[].attributes.body
I have learnt that sound travels by vibrations in the air. We have done some investagions about sound and how they can make different sounds.I also know that some sounds make really loud sounds and some can't .I have also learnt that sound is measured in DB.

# data[].attributes.body
In our sound topic we have learnt about different types of sound.We have learnt about sound liken echo sound waves and more other sounds.My favourite one to learn about was sound waves because I just thought it were really interesting

In the topic sound I have learnt how sound travels in waves, What different parts of your ear vibrate to  catch how loud it is. I have also learnt that sound is measured in DB.

# data[].attributes.body
I learnt that sound can travel at all different speeds and go lots and lots of places and you can make sound go louder or lower sound.
lots of animals can't just hear from there ears because wales can hear sound through there skin it is very cool.

# data[].attributes.body
I learnt about sound waves about ears and how sound travels but I loved when we did our sound investigation and my favourite station was the insturments. some animals can hear high pitch but we can not and we can hear sounds they can not hear.

# data[].attributes.body
I learnt how sound travels,different types of sound,speed of sound ,the vibrations of sound and that sound travels better through water than air.

# data[].attributes.body
I have learnt that sound travels better through dry air and it travels faster under water. Echo's are made up of sound waves bouncing of cave walls.

# data[].attributes.body
I have learnt that sound can have deap sounds and low sounds. I have also learnt that you can also hear loud sounds and quiet sounds. I like sound.

I learned how sound travels and how you can hear sound, I have learned that sound travels faster in water than in air, I have learned that echo's are made in tight spaces against rock walls, I have learned that there are some sounds that we can't hear like ultrasound and infrasound, only dogs can here infrasound because it is so high in pitch and I have learned about sound waves.

# data[].attributes.body
I learnt that sound travels faster in  water and that sound has Ultra sound and Infra sound and we cant here them

# data[].attributes.body
I learnt that sound  makes lots of different noises and how sound travels.I also learnt that there are sound waves.
