Letter to my mum.

 WALT talk  about what we are learning about sound.I wanted to share  with  my family what  I was learning about sound

We wrote letters to our parents to explain what we were learning for our Inquiry. Dear Mum From Amethyst. We are learning about sound. The first thing that I learnt was that if you make a sound the particles move from particles until it gets to your ear and then it gets to the eardrum and it goes through your bones and then to the stirrup and then the cochlea and grabs the message and then it sends a message to your brain. Another fact that I learnt was that sound is energy like light or electricity. Sound is made when objects vibrate. Sound vibrations travel in waves by pushing air particles together. Vibrations can be powerful. The stronger the vibrations the louder the sound. I also learnt that if you have a tuning fork and bang it on the table to make it vibrate then put it in water it will make a splash because of the vibrations. We did an experiment with sprinkles and glad wrap over a bowl. We put the sprinkles on the gladwrape  and made an ahhhhhhhhhhhhhhhhh sound. The sprinkles moved because of the vibrations coming from our  sound. Another experiment we did was with a tuning fork and a string and a ping pong ball. We made the tuning fork vibrate and put it by the ping pong ball and the vibrations moved the ping pong ball. You can feel the vibrations from the tuning fork. They feel buzzy and ticklish. Another experiment was with some rice and a container and a wooden spoon. We made the rice jump by made a loud noise next to the container. All of our experiments showed us that sound is energy because it can make things move. I also learnt that in space there is no sound. The only way that sound can work is if you have air.

WALT find information from the text to answer questions.

Read the text and find the information to answer these questions.

What is sound?

Sound is energy. Sound has power. 

How is sound made?

When you make something vibrate like when you strum a guitar, the vibrations make the air molecules bump into each other. Sound is made by vibrations.

How does sound travel?

Sound starts when something vibrates then the air molecules move and they make a sound wave that takes the sound to your ear.

How do we hear sounds?

Once in your ear , the vibrations travel into the ear canal until they reach the eardrum and then sends a message to your brain and your brain decides what it is.

Why can’t sound be heard in space?

Because there is no air in space. Sound needs air molecules to carry the sound.
