Today we modeled the mid-ocean spreading of tectonic plates.We pushed paper out of a small gap out between two tables . The paper represented the ocean floor and bulges of the paper were the lava flow convection currents pushing the paper up. We measured this because the force pushing the paper up was our hands and is in reality the lava flow, but as the paper grew higher in length from the middle, that was the mid ocean ridge across the ocean floor.

What does this clip say to you?

The clip tells me that even though we are all scattered across the globe and we are separated from one another, we may have different cultures and different beliefs but when we as a whole come together, we are all the same people and it makes us a team or a family.

What questions would you ask about this clip?

Some questions i would ask:

Why did Matt make this movie?

Who did Matt make this movie for?

Why is everyone so happy?

How much did all his travel expenses cost?

What is the meaning of this movie?

What was Matt’s inspiration?

Why did Mr Carr show this movie in this particular project and in this point of time.

I think that Mr Carr showed this movie to us because he wanted us to see that the media doesnt always portray the good view of countries but here we show that one man with a big heart and a little dance can inspire people to come together.Just like ourselves, this movie can bring us at this time to stick together and be happy as one.

Reflection Journal

1. Likes and dislikes of this project…..any suggestions on how to improve???

I liked my group, because for the first time, i was with my mates that i muck around with at lunch and stuff but when we were in class, we actually got alot more work completed than i thought. Some dislikes were that there were no actual lessons on what some subjects were, like even though we did practicals, i can honestly say that i didnt know what i was doing,but i was trying to. We just need some more help  with things and more explanation.

2. What areas do you think you have improved in from project 1 to project 4?

I have improved in my work ethic i think, because i have realised that me not doing as much work will affect my group members and myself. And also my communication skills havwe improved vigorously, seeing as though i never check my emails, i sent emails to my group members and even checked my email.

3. What further skills would you like to develop over the next few projects?

I think the skill that i would like to improve would be to concentrate better and my focusing skills. Because i know that i fall behind in my time of lesson, and i shouldnt just leave everything to do at home.

  1. Analyse why red sunsets can sometimes be more impressive when there is more dust or pollution in the air than usual.

Red sunsets are caused not because of refraction of sunlight, but because of a phenomenon known as scattering in which molecules of gas and dust particles in the atmosphere alter the direction of light rays.

 

-Science Focus 3,Kerry Whalley,pg110

 

Sunsets, spectacular as they can be, are in part the result of all the pollutants we have pumped into the air.

Water, dust, and pollutants act as tiny prisms that cause the light to bend. The different particles scatter and change the light by refracting it; each color is produced by different refractory properties of the junk.

If there were no particles in the atmosphere, there would be no sunsets.

-http://wiki.answers.com/Q/Why_are_sunrises_and_sunsets_sometimes_red

 

Describe what happens inside water droplets to cause a rainbow and explain how you can tell whether a rainbow is a primary or secondary.

Small droplets of water behave like tiny prisms in the sky. The droplets will reach our eyes after undergoing total internal reflection. Droplets higher in the sky refract red to our eyes, while green and blue go overhead. We can tell a primary colour because a band in the sky with red at the top and blue at the bottom. And sometimes a less intensive secondary rainbow can be seen above a primary one.Light reaches our eyes from a secondary rainbow after two internal reflections inside each raindrop. This has the effect of reversing the colours so the bottom band is red.

JOURNAL ENTRY WEEK 2

Investigate the two types of sight defect- long-sightedness and short sightedness.

Find the following information:

 

  1. what causes the defect
  2. the symptoms displayed
  3. propose what sort of lens may be used to correct each vision.

 

1a-Hyperopia- The causes of hyperopia are typically genetic and involve an eye that is too short or a cornea that is too flat, so that images focus at a point behind the retina.

http://www.docshop.com/education/vision/refractive-errors/hyperopia/

  b-syptoms displayed are trouble seeing objects that are close up. In some cases, they may not recognize that they have a vision problem, but will notice that their eyes become tired or sore during such activities as reading or writing.

http://www.docshop.com/education/vision/refractive-errors/hyperopia/

  c-the lens that can correct hyperopia is wearing convex lenses which bend light more so the focus point of the image is brought forward onto the retina.

 

2a-Myopia-Usually develops in children or young teenagers. You are more likely to develop myopia if it runs in your family. Temporary short-sightedness, called pseudomyopia, can be caused by certain diseases or drugs.

 

  b-Trouble seeing objects that are far away.

  • Trouble seeing the blackboard, television, or movie screen.
  • Reduced school or athletic performance.
  • Squints or frowns.
  • http://www.webmd.com/eye-health/tc/nearsightedness-myopia-symptoms

      c- the lens that can correct myopia are concave leses that move the focus point of the image back onto the retina.

    Journal 1- Fibre Optics

    Posted on by jaytang.

    Fibre optic technology offers many advantages when used in medical applications.

     

    a.     describe how optical fibre may be used in medical applications

    b.    identify the traditional medical techniques that optical fibres might replace

    c.     Evaluate the benefits of fibre optic technology to medicine 

    a. Optical fibres are used in endoscopes. These flexible tubes contain optical fibresand can be passed via the mouth into the digestive system to provide doctors with images(magnified around four times) of the stomach intestinal lining. Tumours that would be impossible to treat may be destroyed by laser light sent down an optic fibre cable inserterd nearby.

    b.Optical fibres could replace using a knive to cut open a tumour and destroy it from there but now you can just laser it and its gone. Also having to put a large camera or light down there to try and retrieve images and light.

    c.Well now it makes things alot easier for the patient and also the doctor constructing the surgery. Fibre optics can limit the number of unnecessary surgeries that take place as well as examining the problem more accurately.

    • What influences your values about issues relating to your life?

    My values about issues relating to my life are influenced by other people and by the media. Like when i feel like running out of home, the media portrays running away as a way to get out of home or get out of punishment, but if i was to run away i would run away from the troubles in my life, i would get a hiding. But another way media influences my values about issues in my life is when celebrities don’t go to church then they sometimes influence my on why should i have to go to church.


    • Do you ever compare images/values presented by the media to those of the bible? If so why? If not why not?

    Yes sometimes like when the media only shows people dying when there is a killing rampage it kinda to me relates to the plagues of which happened in the bible and was killing everyone. Also when i look at the media and celebrities influence me to not go to church, then i remember that i have to go to church because Jesus in the bible says that i should go to Church every Sunday.

    Has this project challenged you to examine your values? Why / Why not

    In a way this project has taught me to examine my values because, when the media publishes something, they are not always true or factual. Most of the time they portray things differently and they don’t show you what your not interested in. But yes it has taught me to examine my values because next time i view the news or something that the media publishes then i need to look into it before i believe anything.

    • How do you feel the media portrays social justice issues?

    The media portarays social justice issues as a negative of the world. They dont say why or how this image is like this but they just say post an image there and dont say what its about, because they dont know the true meaning of the image. Like if they show a poor african family, they want us to think that they are truly poor but really they are happy and content with what they have.

    • Has it been difficult to find articles on social justice issues why/why not?

    Sometimes it has been difficult to find a social justice article because the media dont publish everything they want to publish because of legal reasons, and when we want to find something, not everything is there.

    • Do you think that the media operates from a moral framework? Give evidence by using your research.
