Electricity Assessment 2024

  1. What is electricity, electrons, current, voltage, series circuits and parallel circuits.
     Electricity is the flow of electrons through a conductor. This happens when electrons move between atoms in
     a current because atoms have equal amounts of protons (POsitive charge) and electrons (negative charge) 
     attatched to them because of this when one electron moves between an atom it pushes another one away and 
     this process repeats its self creating the flow of electrons and electricity. 
     Electricity is also a form of energy being transformed into heat, light and sound energy. 
     Electrons are the particles that are around the nulears of an atom.They orbit the atom with protons(positive
     charge). Electrons have negative charge in electricity and they are found in all atoms.
     Current is the flow of electricity through circuits. The unit for currents in amp or (A).
     Voltage is how fast an electrical current if flowing by measuring the amount of preasure that pushes the 
     electricity. The unit for voltage is Volt or (V).
     Series Circuits are a circuit that has one line of travel for the electrical current it has componates one 
     after the other and of one fails then all of the componates will fail.
     Parallel Circuits are circuits that have multiple paths that the electricity can travel on and componants
     line up in a parallel line, if one of the componates fails then the others will still go.

Killer diseases–Health

Intro

In health this term we have been learning about death, dying and the afterlife. I learned about different beliefs and practices. Diseases are one the biggest factors in death killing nearly 41 million people each year. Some of the biggest killer diseases are Coronavirus, Ebola brain-eating cancer, M.E.R.S a respiratory disease and the black death which I will be sharing some facts about today.

What is the black death?

The black death was a deadly disease that spread throughout Europe mostly to humans by infected fleas that traveled on rodents. It was called the black death because it killed millions of Europeans during the Middle Ages and one of its symptoms were large apple-sized blisters that oozed black puss.

How it travelled:

The black death disease travelled through touch and air particles being contaminated by someone sick with the disease. But that is only in small populations; The Black Death spread through countries by the trade routes. This is because rodents such as mice or rats carried fleas which were contaminated with the disease throughout the countries and across the border. It could also travel through humans since the symptoms only started to appear about 2 days after you got it this means traders would have had time to cross the border and deliver the things before the symptoms kicked in.

Symptoms:

Some of the symptoms that people with the Black Death disease may have experienced were a fever, shortness of breath because of fluid in the lungs, shivering, diarrhoea, headaches, pain in the back arms and legs, sleepiness and the most common one huge black fluid filled sacks that were generally the size of an egg all over their body.

About the masks:

The masks and body suits that the doctors wore while they were treating patients typically looked like a bird in an oily rag and gloves but this design had a reason. The purpose of the mask was to keep away bad smells such as decaying bodies and the smell taken with the most caution was known as miasma, a noxious form of “bad air”. This was thought to be the principal cause of the disease.

Respecting Other Cultures during DDA

I respected cultural differences by taking time to understand why they might do the things that they do during death. Showing respect while you explore other cultures and beliefs can enhance your and others’ Hauora because It can give you an insight into how they celebrate death giving you a chance to see different ways you could celebrate death. Overall giving you different ways that may be better for your Hauora.

Taking care of your Hauora during grief

It is very important to take care of all aspects of your hauora during grief because a lot of changes are probably happening all at once impacting your mental health. For example, if someone close to dies you could become reserved during grief impacting your social well-being, and stop doing the things you love impacting your spiritual and physical well-being. All of these things take a huge toll on your Hauora and your life in general your friends may stop wanting to hang out with you making your once happy and bright day into a dark and gloomy one. That is why it is very important to look after and be mindful of your Hauora during a time of grief.

renewable energy

Here is a picture or image of my model:



My solar power plant shows how solar panels transform solar energy into electricity. It transforms solar energy
into electric energy that powers a lot of our modern-day technologies.
My energy source is renewable. This is because it will never run out since the sun provides the solar energy.
A solar farm works by the sun shining down on the solar panels. The PV cells in the solar panels then absorb
the solar energy that the sun produces and transform it into electrical energy. The electrical energy is then
stored in the solar panel's batterie. The cable connecting the solar panels to the building acts as a
transportation device for the electrical energy to get to where it is needed in the building.

2024 football bolg

This term in our physical education class, we’ve been practising football skills. From perfecting dribbling techniques to honing our passing abilities, we’ve been focused on mastering the correct execution of these skills.

I have decided to dedicate more of my training sessions to enhancing my passing skills. I’ve noticed that my passes are occasionally off-target and inconsistent, so I want to work on improving the accuracy and reliability of my passes.

Soccer passing is a fundamental skill that plays a crucial role in the game. It involves transferring the ball to a teammate in an accurate and controlled manner. Passing allows for quick and efficient ball movement, creating opportunities to advance up the field and create scoring chances. Proper passing techniques include using the inside of the foot for short and mid-range passes, while longer passes may require the use of the instep. It’s important to focus on the accuracy, timing, and weight of the pass to ensure that it reaches the intended target. Additionally, being aware of the positioning of teammates and opponents is essential for successful passing in soccer.

 

Eyes(How do we see)

The eye, a complex organ, is responsible for sensing light and enabling the intricate process of vision. It consists of various specialized structures such as the cornea, iris, lens, retina, and optic nerve, all working together to capture, focus, and transmit visual information to the brain for interpretation.

Here’s a breakdown of how we see it:
1) Light first enters the cornea.
2) The cornea refracts the light and directs it into the pupil.
3) The iris, which is pigmented, regulates the amount of light that enters the eye.
4) Light enters the lens.
5) The light is focused on the retina.
6) The retina creates an image and converts it into a signal.
7) The optic nerve translates the signal to the brain, where it is converted into an image that we can see.

Part Description Function Part Description Function
Cornea The front part of the eye. It is tough, transparent, and convex. Reflects light as it enters the eye. Lens The lens is a bi-convex it’s a transparent flexible disc Focuses light on the retina
Pupil The pupil is a dark hole in the middle of our eye Allows light into the eye Retina The retina is connected to our optic nerve which is just a bundle of nerve fibers Creates an image and converts it to a signal
Iris The colored ring around the pupil It controls the amount of light going into the pupil. Optic nerve A bundle of nerves connected to the brain. Transports the signal to the brain where it is made into an image.

 

Magic School Review

I’m a year-9 student at MagicSchool and Raina, the chatbot, has been incredibly helpful. Raina tailors her responses to my grade level, explains concepts clearly, and provides support and encouragement. She’s versatile across various subjects, ethical, and always student-focused. I highly recommend Raina as a supportive educational assistant for any student.

How Humans Hear

The first step of how humans hear is when sound waves enter the ear. 

When sound occurs it enters our body through the outer ear also known as the pinna or auricle. When the sound waves hit the pinna it filters and amplifies the the sound. The sound waves then hit the eardrum making it vibrate. “The ear is a paper-thin membrane that vibrates violently when sound waves hit it. It’s really like a drum.”Dr. Mehdizadeh says.

Next the sound travels throught the middle of the ear.

Behind the eardrum lives the middle ear. In this part of the ear’s anatomy, sound waves are amplified before they are delivered to the inner ear.The eardrum is attached to a chain of three small bones called ossicles. These three muscles are the smallest in your body. When the eardrum vibrates in response to sound waves, these muscles are also set in motion.

Heart Dissection

Aim: 
The aim of this experiment was to identify all the parts of a heart.

Hypophosis:
My hypophosis is that the heart will be squishy and it will be layed out just like the photos.

Method:
First we found the soft side of the heart
Then we cut it straight down the soft side of the heart
Opening it up we layed it flat in the dissecting tray to examine

Results:
 

Explanation:
At the top of the heart is the aorta. In the middle is all the heart strings that connect everything together.

Conclution:
Everything did work the way that I expected it to. The only thing that I wasn't expecting was the way it smelt
and how squishy and meat like it was.

Term 2 Wanaga Trip

I believe we should go go-karting session for our upcoming class outing, and I truly believe it would be an incredible idea. Go-karting is an exhilarating and competitive activity that guarantees a lot of enjoyment for everyone involved. This experience would not only be incredibly fun, but it would also create lasting memories for all of us.

Additionally, I believe that it would provide us with a unique opportunity to practice and enhance our driving skills, which could be beneficial for our future driving tests. It’s a fantastic way for us to learn how to drive in a controlled and safe environment. I mean, who doesn’t like the thrill of go-karting? I’m confident that this activity would be a hit with the entire class, and I truly believe it would be an outing that we’ll all remember for years to come.
