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.
