PHYSICS ESSAY : AUTOMOBLIE SAFETLI ——SEAT BELT

By Candy

Now there’s so many people like to drive to travel ,or anything else that they need to drive car .But some people or drivers always because they didn’t wear seat belt ,so they hurt or die in the traffic accident .And so many people ask :What can seat belt really help us ?!What can seat belt do ?!Why we must wear seat belt ?!

We all know that we have to wear seat belts when travelling on the roads where they are provided. We know that we have to wear a seat belt in order to protect us and others in the car or vehicle if we were to have a road traffic accident; we also know that wearing a seat belt is a legal requirement for most people. You may not realize however that there is another reason why you should wear a seat belt.

If you do not wear a seat belt and you are in a road traffic accident, the compensation to which you may be entitled to could be reduced by up to 25%. This is due to a term in the legal world known as Contributory Negligence. In this instance, it means that the innocent driver may have contributed to his injuries by negligently not wearing a seat belt .However, in vehicles such as coaches and taxis that some people may neglect to put on their seat belt if one is provided.



Most injuries to drivers and passengers are caused by contact with the steering wheel, dashboard, windscreen and the sides and roof of the vehicle. Lap and shoulder belts have proven their value in preventing severe injury in the majority of crashes .And if Correctly fitted and properly adjusted child restraints provide protection for children from birth to 16 years of age.

However, many people refuse to wear seat belts. They say that the belts are too uncomfortable, or they say they are only driving a short distance. They may also say that they simply forget. With the growing prevalence of state "primary laws," in which police officers are allowed to stop cars at random to perform seat-belt checks, people are clearly more careful when they know they may be facing a fine.

And now we almost know what can seat belt do .So from now let’s do it together .When we get on the car the first thing I think is wear on seat belt .

One person ,one seat belt .

Seat belt ,save life .





  • END —

Candy: I liked your essay about seat belts. I can see that you feel strongly about them. I’m curious about why your essay doesn’t answer the leading questions or match the grading criteria. I will attach the task description to this document so that you can write a better essay for your revision (see below).

Scientific Essay: Automobile Safety

TASK

At the inquest into the world’s first road traffic death in 1896, the coroner was reported to have said “this must never happen again”. More than a century later, 1.2 million people are killed on roads every year and up to 50 million more are injured. These casualties of the road will increase if action is not taken.

— WHO | Road safety: a public health issue

http://www.who.int/features/2004/road_safety/en/
From the statement above, it is clear that road safety is a growing issue around the world. Your task is to write an essay which describes how physics is used to tackle this issue.
Leading question


  1. What is the local/global problem related to this topic?

  2. What are the scientific applications used to address the problem?

    1. Select one application to discuss.

  3. How does the scientific application work?

    1. Use scientific theory or concepts to explain the application.

  4. How effectively does science and its application work?

    1. Search for data to support your statements.

    2. Explore both the usefulness and limitations of this application.

  5. How does the scientific application interact with One World factors?

    1. Select two factors to discuss.

    2. Search for data to explain how the application interacts with the selected factors.




One World factors

Moral

Ethical


Social

Economic


Political

Cultural


Environmental


Instruction

- You should include diagrams, charts and graphs to support your writing. When you use a chart of graph, you must discuss it in your essay.

- Include a bibliography with references for your work.

The student describes the effectiveness of science and its application in solving problems or issues

The student describes how science and its application interact with at least two of the following factors: moral, ethical, social, economic, political, cultural and environmental.





5-6

You have explained in your own words the physics behind your chosen application.

You have described the effectiveness and limitations of physics and of your chosen application in addressing the problem (How do you know your chosen solution works? Why is it not the perfect solution?).

You have described how your chosen application is affected by or affects two of the One World factors, supporting your statements with data and examples from trustworthy sources.



Criterion B: Communication in science Task Clarification

0

The student does not reach a standard described by any of the descriptors below.




0

You have not handed in an essay for this assessment.

1-2

The student uses limited scientific language correctly

The student uses appropriate communication modes, such as verbal (oral, written), visual (graphic, symbolic) and communication formats (laboratory reports, essays, presentations), consistent with the level of complexity of the units of work covered, to attempt communicate theories, ideas and findings in science

The student rarely acknowledges the work of others and the sources of information





1-2

You have used some scientific language in your explanations.

You have included diagrams, charts or graphs to illustrate your statements.

You have a bibliography.


3-4

The student uses some scientific language correctly, consistent with the level of complexity of the units of work covered

The student uses appropriate communication modes, such as verbal (oral, written), visual (graphic, symbolic) and communication formats (laboratory reports, essays, presentations), consistent with the level of complexity of the units of work covered, to some extent communicate theories, ideas and findings in science

The student partially acknowledges the work of others and the sources of information used by documenting them using a recognized referencing system.





3-4

You have used mostly correct scientific words from the physics we have studied in class in your explanations.

You have included diagrams, charts or graphs to illustrate and support your statements. They are labeled and have titles.

You have listed your sources in a bibliography.


5-6

The student uses scientific language correctly, consistent with the level of complexity of the units of work covered

The student uses appropriate communication modes, such as verbal (oral, written), visual (graphic, symbolic) and communication formats (laboratory reports, essays, presentations), consistent with the level of complexity of the units of work covered, to effectively communicate theories, ideas and findings in science
