Sonar and Sound Pollution.

Even if its birds talking and dogs barking cicadas making weird noises. But animals that a underwater is hard to communicate.

There is thing called Sonar, sonar helps humans to find shipwrecks and undiscovered things. In the middle of all the sonar is underwater creatures like whales dolphins and other animals that use echolocation.

Sonar stands for sound navigation. Sonar was used to find the plane flight MH730

Tech@Tamaki College

Every tuesday Year 7 & 8’s goes down too Tamaki College and do tech. There a 3 groups, Graphics, Hard Material and Food tech.

Im in Food tech. Our subject for food is Healthy eating. Our first day we made Pasta something. My first group was Hard Material. In hard material you get this workbook where you fill in questions. I don’t know what you do in Graphics.

The second day we made Enchilada. You need onion,capsicum,garlic aioli, pasta, cheese, sour cream and 1 or 3 wraps.

My favourite is Food tech it's because you can eat.

This is my presentation of how fast does sound move.

Being safe underwater

Are you being safe underwater...? Too be safe you gonna need to swim 200 meters. Every year thousands of people die drowning. In New Zealand 97 people die frowning in 2008 So it’s really important that people go swimming lessons and learn the basics.

In summer people like going to the beach its because its free dont need to pay and these no life guards. The only thing is, sharks will eat them and the water is dirty. Now a days people go swimming lessons so they won’t drown.

Sebastian Sound

This is me and my groups first attempt at explaining sound.

Like many terms in science, Sound is formed from a vibration and from mechanical waves. in everyday use, sound refers to what the ear can hear. Sound can be pleasant unpleasant hard or soft high or low. The scientific meaning of sound is based on an understanding interaction between matter and energy, what the brain hears of sound or interprets gets its start from the energy of moving molecules of air.

When a guitar string  vibrates energy comes from vibrations. these oscillating sound waves can move through substances like water dirt or solid rock.

I don't really know if it's entirely true but it's what I heard.

When I find out a bit more I will tell you.
