[Science] - "Define & Calculate: Density and Pressure"

Throughout the past few weeks in our Science class with Mr Tyagi, we've been learning all about motion. As known, Newton's laws of motion were discovered to be true or accurate, and was carried out through generation to generation, and now we've learnt the ways of motion. In the past lessons, we've learnt about acceleration, mass, force and weight. Today's lesson, we've covered density and pressure, and here a few questions I've answered down below. Thank you very much for visiting my blog, I appreciate it a lot!

[Define & Calculate] Density and Pressure:

1) Describe density and pressure with units :

The definition of density is the state in which something has a degree of compactness of an object or some sort of substance. Density can be calculated with Mass (m) and Volume (v), as in… (density number g/cm3) Pressure how ever is like a physical force in which is removed on or against an object, in which you may have contact with. Pressure is related to force, and the unit for pressure is Pa, and to calculate it, you must divide force by area, its meter-kilogram-second (MKS.) Also, the less dense an object is, lower the pressure, and the more dense the object is, the higher the pressure is included.

2) Describe how friction can be both helpful and unhelpful:

Friction can be both helpful because cars or vehicles that we have now wouldn’t be able to move along the ground or road, and the brakes of the car wouldn’t allow you to stop the car. Friction can be unhelpful when we are trying to push something very heavy along somewhere we need it to.

3) State Newton’s Laws of Force and Motion:

Law 1: Objects at rest sustains (it is stationary), and objects in motion sustains in motion

Law 2: Acceleration of an object is dependent upon two variables.

Law 3: Every action is equal to an opposite reaction.

4) Explain why objects do not fall at the same rate:

Objects don’t fall at the same rate because they have a difference within them, such as a difference in mass, force and acceleration which makes it much heavier or lighter, and the acceleration will increase in which is dependent upon its weight, and the resistance of air when the object is falling would be decreased, which is also dependent on Earth’s gravitational pull. Earth has a pull gravitational force of 9.8 m/s2, and the objects will depend on the gravitational pull of Earth upon its own force. Therefore, objects do not fall at the same rate because, basically… everything is “dependent” upon how much weight, mass or force is applied or in the object.

[Health] - "Effects Of Alcohol On The Body"

Greetings and welcome to my new blog post! Over the last couple of weeks within this term (Term 2) in Health class with Ms Dougherty, we've been focusing on drugs and alcohol. We've learnt all sorts of things about alcohol, such as the effects that has on you, your body and etc. Here is an image informing you of the task/activity we've been doing during class time this day. So we have here... the effects to of alcohol on your body, and also the various types of what alcohol causes; such as addiction. What I found interesting within this lesson is... alcohol poisoning, I didn't know at first of what alcohol poisoning was, until I researched information on YouTube, that it affects body temperature, blue pale skin. Thank you for your time!

"Reflection Writing"- Term 4 Week 9

SWALL :)
Check out the video above for the camp to Marsden in term 1. There will be a little saying that our year eights came up with and it is... S.W.A.L.L and it means how to (show what awesome looks like). Hopefully you enjoy the video made by our very own year eights.

Introduction:

Talofa Lava, my name is Vaifoa L.S and I attend Pt.England school as a year eight student. What I will be writing today will be a reflection that reflects to what our days at Pt.England school has been like over these couple of terms in 2015. Read along to hear all about my journey in 2015. If there are any questions or thoughts please leave a comment below.

About me section:

I am 13 years of age and I am from the islands of Samoa. My best subjects out of all subjects is art. My favourite thing to do when I'm bored is to go out for sports and play really fun games or just go for a sleep. I also love to eat fried chicken with potato salad. I have 7 siblings well including me it’s 8 of us all together.

My favourite things that I enjoy doing when I am really bored, is that I like to go out on the field or a park and play sports perhaps football as in soccer with my siblings and sometimes my whole family. The sport that I enjoy playing at school is soccer. I mostly play soccer with my friends here at school and we play it all the time.

There are not many things that I am good at but here are the things that I am quite good at and that is... perhaps, writing, soccer, mathematics, playing sports, computing knowledge, drawing (graphic art) on paper and on digital drawing. I am quite good at these things because I really enjoy doing them. I love to participate in things even though they are not suitable for me.  

Throughout the overall experience of being part and to be able to learn in the team five intermediate classes. I am really proud of myself for reaching my achievements in 2015. This year, I have been feeling really excited about the events, trips and camps that we have already participated in.

The thing that I found satisfying (what I have enjoyed) about this year with team five was the events, events and the events which was athletics and etc like the sports. I found that fun and exciting. I have always wished that I could be a sportsman when I grow up so that i can make my family and friends proud of what I have accomplished as a student @Pt.England school.

Out of everything that felt difficult will always be the tests and probably the work that we’ve been doing throughout this entire year. But the thing that I find especially hard for myself would be just the tests. But as the tests comes to an end I feel happy that I passed it.

From a scale of one to ten, for this year, I will probably give myself a eight or nine. I gave myself a eight or nine because this year has been the most exciting year I have had out of all my years attending Pt.England school in 2015 as a year eight student.

As a year eight student in pt.england school, in the team five area, I have been contributing within the team five events that have been completed throughout the year as of from the first term, we had to fundraise money so that it could help us with the year eight camp to Marsden. We’ve fundraise for many of things this year and I would like to thank all the parents and people who helped us to fundraise.

For the upcoming year which is 2016, I am looking forward to learn much more and to pass all my tests. What I am also, looking forward to is, hopefully play some sports for the school I will be attending in 2016 which will be T.C (Tamaki College).

The things that I would probably find nerve racking for college is the tests or what college people call it... exams. I have heard- from my college friends in their ninth grade, that it was really difficult for them but I think that I can pass it as I keep improving my studies. What I also find really hard for me is meeting new friends at college.

The thing that I would really have to change in 2016 as I will be a year nine student, would be the effort and being more active in my work. I would also have to be into focusing more so that I could approve throughout my college years. I could also, maybe change my attitude to make life much more easier depending on what decision I make and hopefully I can make really good choices.

For my tutor teacher that I will be getting to meet in the following year,  I would like to say that the things that I am really interested in doing would be the things that I enjoy doing perhaps, like... english, cooking, mathematics, science or biology as I am trying to learn more about the world for its behaviors and for the natural environment around the world. I find science pretty fun as my teachers started talking about the nature.

In 2016 when I go to college, I would probably need more help with my education. I would also need more help with my learning of some sort. Probably some more help with what I am looking for in the future when I am older because I haven’t yet decided what I am going to do in college.

Conclusion:

I would love to keep writing more about my journey here at Pt.England school but this reflection has sadly come to an end and hopefully you have enjoyed my reflection, probably most of my entire life in 2015 that I have written in this story. Feel free to leave a comment in the description box below. See ya next year my future teacher!

 

Warren Pohatu- Turtle Drawing

Warren Pohatu Art Work Steps

1. Research an intricate outline of an animal, for example...... something that represents you.

2. Once you have chosen your outline of an animal, you then start drawing it without no details just the outline of that animal you came up with.

3. After you have completed step 2, you then begin painting the inside of your animal warm or cool colours. I have chosen a cool colour for my animal on the inside and warm colours on the outside. It's your choice, do whatever you imagine.

4. Lastly, when you have finished painting the colours on the animal or background, you start pasteling the inside warm or cool colours. You can pastel every inch of the animal or the background with any pattern or design.
