Cathy Freeman Biography

Cathy Freeman, aged 43, is a retired Olympic Gold Medallist. Ever since she was young, Freeman aspired to be a sprinter representing her country in the Olympics. In her primary school days, she could easily beat any competitor she faced in a race. Noticed by many, Freeman was awarded two scholarships. One to Fairholme College and another to Kooralbyn International School, both in Queensland. At Kooralbyn (1989) was where she was professionally was coached for the first time.

In 1990, Freeman competed in her first Commonwealth Games and came first as part of a 4×100 relay team. That is where she became the first Indigenous Australian to win gold at the Commonwealth Games. Then the next time she competed in the Games, she won first place for the 200 and 400 metre sprint. The 1992 Barcelona Olympics were Freeman’s first although in these games, she didn’t make it to the finals whereas in 1996 in the Atlanta Olympics, she won silver. Throughout these years, Freeman also managed to be awarded Young Australian of the year in 1990 and Australian of the Year in 1998.

She participated in many other races throughout her time, sometimes winning gold and other times not.

Freeman used many values. One of them was Freedom, as she always wanted to be an Olympic runner and she was able to fulfil her dream simply because she was free to do so.

Another was doing her best. Freeman obviously trained long and hard to accomplish participating in the Olympic Games and achieving this cannot be done without 100% of her effort.

She also used Integrity when she was either training or running her races. She had a goal to be the best she could be and she strived to carry out her dream of winning gold

Scientific Lab Report

Aim:

To observe what happens when light reflects off a mirror after passing through glass.

Hypothesis:

We believe that the light will travel through the glass and reflect off the mirror. We believe this because the glass is transparent.

Material:

  • Torch
  • Glass
  • Mirror
  • Ruler

Method:

  • Set light,glass and mirror apart 15 cm centimeters (make sure they’re lined up straight).
  • Turn on light source.
  • Set light and mirror 15 cm apart and turn on light source.
  • Observe/ Record  the outcome of both experiments.

 

Observation:

As soon as the light beam hist the glass, the light started to fade. Whereas without the glass, the light started to fade at around the 20 centimeter point which is further then the glass. The reflection without the glass is a lot stronger then it is with the glass obviously because there is less light traveling through the glass.

Explain:

In our research we discovered that sun rays are initially blocked by the glass apart from the 50% that is able to travel through. When that 50% of light passes through, it tend to fade as soon as it does. The only way to stop a light wave is with something that will actually absorb or scatter the light. With glass, there is not much there to either absorb or scatter the light so it just carries on through as a faded beam. The reason it fades and doesn’t completely disappear is because glass has a small amount of electrons. Electrons are what absorb the light and with a small amount, like glass, it can’t absorb all the light in total so the rest of it keeps traveling through the glass.

Conclusion:

In conclusion, we discovered that light does travel through glass due to the electrons inside it. Our research was quite helpful with this experiment and it was interesting doing it.
