JOURNAL 4

Complete the following reflective journal questions on your edublogs account.

1. What did you like about this project?

   I liked the way that we did a lot of pracs.

2. What did you not like about this project?

   Journals and writing up prac reports.

3. Suggest 3 ideas that could improve/make this project more engaging.

   -Dont do as many journals.

   -Give us more freedom (choosing groups, etc.)

4. Did you like the driving question? Explain why/why not.

   Not really because we do the same topics every year.

From modelling this experiment its obvious that when plates collide mountains or even volcanoes are formed.

From this experiment, the convection currents move in an upward, circular motion.

In conclusion, when a thin beam of white light is refracted by a triangular prism,m it is split into the colours of the rainbow.

think, pair, share activity.

1. What does the clip say to you?

-Anyone can be happy no matter what there situation is, or there living condition.

-To be a family/community.

2. What questions would you ask?

-Why are they dancing the way they are?

-Why are they so happy?

-What made them so happy?

3. Why are we showing this clip at this time of the project?

-To help us come and work together as a year group, as a class, as a team, and as friends.

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

I hated journals. I didnt like writing out the pracs, but i liked doing them:). I think you should make class more fun.

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

organisation

• 3. What further skills would you like to develop over the next few projects?
  work ethic and time management.

Journal Entry 1.

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

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

Instead of having a major operation they can just cut a whole in you and stick a little camera in you.

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

Use to have to have like full surgery. cut open and everything.

1. Evaluate the benefits of fibre optic technology to medicine

they made big operations small.

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

Because the pollution makes an illusion as if it is part of the sunset and ads more colour.

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

Inside a rainbow drop, as it falls it is like an optical instrument and makes the colours of a spectrum and a way you could tell if it is primary or secondary is by inspecting it .

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

Find the following information:

1. What causes the defect
   Short-sightedness
   -tends to run in families
   -certain diseases or drugs (type 2 diabetes)

   Long-sightedness
   The exact causes of long-sightedness are not well understood. It is known that the eyeballs of long-sighted people tend to be smaller than average, with less curved corneas – the main optical component of the eye. There may also be a hereditary component, as the children of long-sighted parents can be long-sighted.
   

2. Yhe symptoms displayed
   Short-Sightedness
   Short-Sightedness causes distant objects to appear blurry and unfocused, while nearby objects remain in focus.
   
   Long-sightedness
   Children

   • red, or tearful, eyes,

   • they squint when looking at close objects,

   • they complain that their eyes feel tired,

   • they blink more than normal, and

   • they seem reluctant to, or have problems with, reading.

   Adults
    

   • objects that are close appear out of focus,

   • you find you have to squint to see clearly,

   • your eyes feel uncomfortable after an activity that involves close focusing, such as reading, writing, or working on a computer, and

   • you experience pain or burning in or around your eye.

3. Propose what sort of lens may be used to correct each vision.
   Short-Sightedness
   Short-sightedness can usually be corrected by wearing glasses or contact lenses. Some people wear contact lenses, but others feel more comfortable in glasses. Your optometrist will discuss with you what options are available.
   Contact lenses tend to be more expensive than glasses, and you have to be comfortable touching your eyes to use them. They need to be kept clean and some types require a lot of care. A popular type of modern contact lens is the daily disposable contact lenses, which are worn for one day and then thrown away. When you wake up the next morning you put in a brand new pair. There is no cleaning or storing with these lenses.
   Glasses are usually recommended for children. They are also easier than contact lenses for older people. Glasses are also a better option for those people who find contact lenses fiddly and don’t like touching their eyes.

   Long-sightedness
   Glasses and contact lenses are the most common method used to correct most refractive errors, including long-sightedness. The lenses in glasses converge the light rays, moving the focus back onto the retina.

   Young people who are slightly long-sighted generally do not have problems. If they do, they may need glasses for close work such as reading and using computers.

   Older people, or young people with significant long-sightedness, often have problems because focusing requires a lot of effort. Their vision is more likely to be blurred, especially for close objects, and they usually need glasses for reading and sometimes for distance vision.

   For people with significant long-sightedness, contact lenses can be the best form of correction as they provide better vision and are preferable to wearing thick glasses. Contact lenses can be made from different materials and can be disposable or non-disposable.

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

i feel that there un trustworthy and uncomfortable with there opinions because there always so open minded.

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

Not really because there is so many and because they mimic a new celebrity every day or every week.

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

No. becuase they twist around a story so much, there veryy biast in nearly all there work.
