Week 12

The final week of SCIT140 and of semester 1! This has been such an insightful journey; my knowledge on science and sustaining our world for the future has improved drastically.

Our children need to learn about our world. At a primary age kids soak up so much information and they need to absorb the right things. In order to help them, class rooms needs to be interactive. Such small minor experiments will stick with children like many of still remember to this day. Growing grass out of a stocking, making volcanoes erupt, these simple designs show children how the world works. Maybe not to a molecular scale, but one that will help them grow and give them their consciences.

This may be an end to my SCIT140 journey, however it is not my end in creating a more sustainable earth

Week 11

Are humans still evolving?

Yet again we are addressing this issue; and after everyone had time to think in the lecture theatre, not one person could disagree. Maybe we’re not changing to a  completely different creature however the small changes are evident over time.

Our world is slowly dying. The way many are living is way above what the earth can provide. All semester we have discussed sustainability, but what about unsustainability? At the start of this year, my lifestyle estimated 3 and a half planet earths would be needed if everyone lived the same way. It isn’t acceptable especially when so little is being done to preserve the earth we live in. As humans we:

  • We extract large flows of materials from the Earth’s crust
  • There is an accumulation of substances created by society
  • We inhibit nature’s capacity to run natural cycles
  • We create barriers to people meeting their basic needs worldwide

If there is one thing I can take away from all my new knowledge this semester, it is that we need to educate. Not just as teachers; but as parents, siblings, elders. if the youth of today can not grasp the concept of sustainability we can not expect the world to survive. It is up to us to start making a change, but it is up to our children to save the world.

Week 10

It’s the week of my great biodiversity group presentation. You can find our cool Facebook page if you follow the link: https://www.facebook.com/acubiodiversity/

Informing people on diversity is so important. People need to know that positive changes for the environment will help us to preserve

Are humans still evolving?

We are all said to come from monkeys? It sounds ridiculous and I know I can’t fathom it but if we bring it to something smaller like the finches. Darwin’s theory of evolution shows the change in the finches’ beaks depending on their habitats.

In the end its survival of the fittest.If the world is dominant of one food type then animals adjusted to eating it will thrive and survive, however that will lead in the diminish of animals who are unable to eat that food.

Us humans are very advanced.The technology we have created, from the wheel to the robot, have set us apart from all other species. But we did not start at the top, over time our brains have developed and we are able to come up with new amazing innovations.If we stop educating our children we stunt human brain growth for the future, education is so important to our future because once we’re all gone, what’s left?

Week 9

Australians know for its unique flora and fauna. Our separation from Gondwana millions of years ago gave Australia some of the widest diversity in ecosystems compared to the rest of the world. Even the abiotic factors within Australia are so different; from our dry grass deserts, to the great coral reefs along the eastern coast.

The formation of the different mountains in Australia is astonishing. Being a 5 minute drive away from the Organ Pipes national parks, I take the structure for granted and only see it as an exhausting practice hiking walk. The Organ Pipes, which is a formation “set of basalt columns formed by the cooling and cracking of molten lava”(Parks Victoria).

There is so much knowledge one can gain on the formation of what most think is a ‘normal’ mountain. If we can start our students out small, maybe with basic volcano experiments, then one day we might create future scientist that will discover even more that will help sustain the world we live in.

Week 8

Week 8 was all about energy. Energy is what makes everything happen, from the simple movement of breathing, to riding a bike and to operating a factory. The universal measurement for energy is joules. One Joule is the amount of energy needed to lift a 100g object a distance of 1m on Earth (given the gravity on Earth).

Every living creature; human, animals, plants and every living organism; use energy and have their own process on how to do so.

And that is where the concept of Biodiversity comes in hand. Biodiversity refers to all living creatures. It is the makeup of the world we live in, when the word is broken up into 2 we get a basic definition of, the study of living organisms and their differences.

Within one species you can get so many variations, their slight differences are how they’ve slowly transformed to survive their habitat. Below is a screen shot of the National Geographic biodiversity game. This is the description attached

Below are eleven boxes containing icons that represent plants, animals, and other major categories of living things. Match each icon to the appropriate number representing the amount of identified species within that category of life by dragging and dropping the icon into the square above the number you think is correct. When you have placed all 11 icons, correct answers will be outlined in green and incorrect answers in red. Continue to shift around incorrect answers until all are correct.

Week 7

Matter cannot be created or destroyed. This was a very hard concept to grasp at the start of the lecture however with a visual representation of this happening (an image of a house after a bush fire) it was easier to put 2 and 2 together. When a house burns down it doesn’t just disappear, products either burn down or turn into dust. One object becomes another. And that’s how to simply put the phrase ‘Matter cannot be created or destroyed’.

In order for something to change it involves the transformation of energy. The 6 types of energy a shown in the picture below:

Fuel is a type of energy and one of the most important fuels is oil. Oil is used for cooking, transportation, as well as building buildings and many other things. However this important type of fuel is diminishing, since the peak of its discovery it has only continued to decrease. Nothing can replace oil and our world relies on it. We must teach our students to think of ideas that use different types of energy; society can use wind power, waterpower and solar power. They’re renewable types of energy and something we don’t need to worry about becoming extinct to our earth.

 

Week 6

Halfway through the semester already, it’s so shocking how fast time passes. That’s another reason why we need to change the way we live today.

Water is what makes the world go round. Part of this week’s activity was to list some purposes of water. People mentioned that we need it to survive, it keeps us hydrated and that every living organism needs it in order to survive.

It is necessary to teach people the importance of water, especially since “Freshwater makes up a very small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. The rest is saline and ocean-based. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields.” (“Clean Water Crisis, Water Crisis Facts, Water Crisis Resources – National Geographic,” n.d.)
