Hi everyone,  I am writing about a Indigenous project I made with my friends. What we did was, we got a poster, and we wrote about the Community we chose. Our teacher Ms. M,  she said we are doing a project about the people who used to live in Canada. She laid a bunch of books on the carpet and they all said a bunch of Indigenous Community. We chose CREE! The cree people lived around Saskatoon, Hudson bay and Edmonton. We shows Cree because they seemed very cool and fun to learn about. And it was! 

There flag Was black and red and yellow

Ways of Sound: Hi world, Lyla here. I am going to talk about some of the stuff I learned in Science.  I learned about Sound!  In my blog post I will share information about:

• What is Sound
• What are vibrations
• The tuning fork experiment
• Kazoo
• How does a ear work

Sound Rooms: If you were in a sound room, and if you scream, Nobody would hear you. That is because the sound did not bounce of the walls. The echo does not bounce

Questions: Here are some of the questions that my teacher asked me and I answer, Why can you hear someone who is in another room? My answer: Sound can be Reflected, that means it can bounce off the surface you are near. Question two: Why do we hear echos? My answer: The noise bounces off the wall, goes into the air into your ears. Question three: In a recording studio the walls are covers in bumpy foam. Why would they do this? My answer: When someone is recording you do not want the sound to reflect into the room. Question four: Name multiple objects we have to allow us to increase the volume of a sound. My answer: Speaker, Microphone, Headphones. Question five: Explain why we can hear sounds better in air then we can underwater. My answer: You can here the voice only a bit, that means it absorbed, It can bounce off some things.

What is sound: Sound can be absorbed, modified, and reflected. If sound is absorbed that means you are underwater. You can here a voice a tiny bit, but not a lot. Then there is reflected that is also a word for bouncing off things. Modified means sort of pitch and loudness.

Experiments:  I have done two experiments so far, The tuning fork one and the Kazoo one. What we did for the tuning fork is: I used, Tuning fork, Yogurt Container, Plastic rap, Scissors, Rubber band, Salt, Water. What I had to do is, 

• Cut a piece of plastic wrap and stretch it over the top of the yogurt container
• Hold the plastic wrap in place with rubber band. Be sure the plastic wrap is tight, but do not rip it.
• Sprinkle some salt on top of the plastic wrap
• Hit the tuning fork on the edge off your shoe once, then hold it close to the Salt (do not let it touch anything )
• The piece that’s four and five but this time tap your shoe multiple times
• Repeat 4 and 5, but this time gently touch and plastic wrap with the tuning fork

Experiment number two:

• For the Kazoo( If you do not know what a Kazoo is here I can tell you) What I did was I grabbed a toilet paper roll, 
• Then some different mitral of  Plastic wrap, Tissue paper, and Tin Foil
• I grabbed an elastic
• I took the roll, the Tissue paper and wrapped the elastic around it
• I blew through the empty side and it made a noise!
