Science of the Arts: Sound

Aim: I want to find out how sound and speech work.

Research: There are two types of sound waves; Transverse and Longitudinal. Transverse waves go up and down, like a bunch of people standing in a line and bobbing down and coming back up one by one. Longitudinal waves travel out and away from their source in a straight line at the speed of sound, which can vary depending on where you are and what temperature it is.

Experiment:

Equipment: 3 wine glasses, 1 1/2 cups of water, plastic spoon

Method: Fill the first glass with 3/4 cups of water, the second with 1/2 cup and the last one has the rest. Use a plastic spoon and GENTLY hit the glasses in this order:

3-2-1-2-3-3-3

2-2-2

3-3-3

3-2-1-2-3-3-3

3-2-2-3-2-1

You've just played Mary Had a Little Lamb on wine glasses!

Sorry, the quality isn't the best!

The explanation for this:
Each glass makes a sound when you tap its side with a spoon because the spoon causes a vibrating sound wave. The sound wave travels through the water in the glass and eventually reaches your ear. Each glass makes a different sound because the sound waves travel through the water at different speeds, causing vibrations at different frequencies. (Frequency refers to the number of times a sound wave vibrates per second). The glasses with more water make lower sounds due to the amount of water causing the vibrations to be slower, causing a lower frequency. The opposite goes to glasses with higher sounds.

In conclusion, the experiment was a success. Next time I would try different shapes and sizes of glasses with the same amount of water.

What does "Introduced Species" mean?

An introduced species is a species of animal that was not already here when the Europeans came to New Zealand.

Why were they brought to NZ?

Some were brought accidentally, some were brought on purpose to bring a bit of home with them.

Why have their numbers exploded?

As soon as they saw that they had no predators and plenty of food, they bred and soon the country was full of them.

What effect do they have on our native plants and animals? 

Some eat our animals, some eat their eggs, some destroy our plants, some have no effect at all on our forests and animals.

How is the DOC (Department of Conservation) trying to get rid of them?

They have attempted using 10-80.

How are stoats and weasels affecting our native things?

They are eating the eggs of our native birds.

What control methods are being used?

10-80 and possum traps.

Are those methods any success?

Yes.

Study: Mokohinau Stag Beetle

The Mokohinau Stag Beetle is a large wingless beetle living on Lizard Island in the Mokohinau Islands off the coast of Auckland. They live in a patch of vegetation about the size of a living room. They are extremely close to extinction.

Their cause of extinction are storms and forest fires. Only nine have been seen at the same time.

People have driven out rats from the island. This has had no effect.

SAVING THE WHALES

Here I will be demonstrating how we can save Orca whales.These creatures are rare to see in the wild and are extremely endangered due to their favourite food becoming endangered because of humans making dams that cover up their spawning grounds. Whale watching is also having a crucial effect on their hunting ability. The boats getting too close causes the whales to have to move out and reduces their echolocation when hunting.

The governments of different countries are trying their best to help restore the numbers of the Chinook Salmon, the Orca's main food source and banning boats from getting too close to the whales. These are not having much effect.

SAVING YELLOW-EYED PENGUINS

Here I will be demonstrating how we can save Yellow-Eyed Penguins.
Introduced predators and habitat loss are the main causes of this penguin's slow demise. The New Zealand government are trying their best to get rid of these predators and are somewhat succeeding. 

Studying Diseases - Gallstones

Gallstones happens when product in the gallbladder dries and blocks bile output. This means that you won't be able to absorb fats, causing a high chance of obesity.

Gallstones can be healed naturally, but sometimes you will need treatment to get them out. The only medication you will need will be cholesterol pills.

Organ Jobs

Brain: This organ sends all the signals to your body to tell your limbs to move. It also helps you recall different things and remember them.


Eyes: This organ allows you to see objects in front of you. However, some people that have eyes still can't see. This is called being blind.


Esophagus: This tube in your throat helps your food and air go to their respective places. However, sometimes it will accidentally send food to your lungs.


Lungs: If you didn't have lungs, you wouldn't be able to breathe. If you ruptured your lungs, you would die.


Heart: This organ is the most important part of your body. This allows the blood to pump around your body and keep your organs moving. You will stay alive as long as your heart is still beating.


Liver: This organ harvests the fat in your body and turns it into energy. The liver makes bile, which helps to break down the fat.


Stomach: Your stomach digests food using acid that your body makes especially for digesting food. Sore stomachs are caused by eating the wrong kind of food.


Large Intestine: This intestine is wider and shorter than the small intestine. This intestine works with turning waste into feces.


Small Intestine: This intestine is longer and more narrow than the large intestine. This intestine works with turning food into enzymes to be absorbed.


Rectum: This is where feces goes to to go from the large intestine to the anus.


Anus: This is the final place in the digestive system that feces goes through before it is discarded.


Pancreas: This is where the digestive acid is made before being transported to the stomach.


Gall Bladder: This is where bile from the liver is stored.


Spleen: This organ destroys worn-out red blood cells, filters the blood and makes white blood cells.


Appendix: This doesn't really do anything.

Art Term 1

This is my art for Term 1 2017!

This is the concept art of my character. Her left eye is red with a star-shaped scar over it and her right eye is hazel. She's a sorceress that can control fire, ice, thunder and water. She has about 7 black dreadlocks and a dress made of flax and feathers.

This is my character in her whole.

This is the unfinished project.

Week 4 Term 1 2017 Blog Post

P.A.T.s

This week we have our P.A.T.s. We have the tests every day at Period 2.

Learning Conferences

This week on Thursday 23rd we have our Learning Conferences. The students come with their families to discuss their next steps in learning.

Te Reo Maori

This week in Te Reo Maori, we discussed our family tree. Matua Corey was away, so he sent us all a Google Doc with our task. The task contained 6 tables. The first was details about our dad, the second was details about our mum, the third was details about us and the last three were details about people we look up to. I only finished one of the last three because I don't really 'look up' to many celebrities.

This is the brief rundown of Week 4
