Volume, Density and Mass

😎 Volume, Density and Mass 😎
Kru Gary's Class

So, today we have done experiments of volume, density and mass, so what we did was we have sample numbers and weigh it on the measuring stand. We measured and got the results. Add a 150ml of water in a beaker - and drop the rocks into it. If the water gets higher than 200ml we will use a graduated measuring tube to measure it up and add it to the total number of 200ml. After that, we calculated the density of the volume and mass. By doing that, we divide mass by volume. That's the final result.

The Impact of society on environment

😈The impact of society on environment😈

I see that the environment here is very polluted, you may ask, why? The obvious answer is that people are using gasoline to power their cars which make acid rain - which is going on to another topic. As we use cars which are in use of this - carbon monoxide is being polluted into the sky - then, acid rain is being created and the impact of acid rain are; Damages buildings, polluted rivers and corrupted trees. This will certainly remain in the water cycle for decades, centuries or even millenniums! 

Acid rain will make contaminated rivers and will harm our food chain. We know that water is liquids, not gases, not solids. Water flows just like liquids, I see that as more of these happen - it will contaminate the rivers and the ocean. Think of us - we can filter these kinds of water, but no animals have the mind to think what acid rain usually is (which means they can't filter the water). What happens then? They become endangered, they die and harm our food chain. Then? We all (may die or may not die) we wouldn't grow because there aren't any proteins in our daily lives. End of the story.

We see that heat may create global warming and the greenhouse effect. What global warming impact our daily lives (or animals' daily lives?) The thing here to talk about is that polar bears, penguins, and the Arctic animals will suffer because of icebergs melting. BUT there is a theory that the cold parts of the land - ice wouldn't melt - it would be hard to melt and would stick together. Therefore - ice wouldn't be too easy to melt in the arctic parts. But as for humans - about 37 degrees Celsius is about our "heat limit" so if there were to be a heatwave includes of global warming - we wouldn't be able to stand the heat of it.

Moving on to the next topic: Oil Spills, what are they actually? They are the release of a liquid petroleum hydrocarbon into the environment, especially marine areas. It pollutes our marine life; fish, octopi, all of the others too. This is polluted life, it harms the marine life: it's already enough for our world, therefore let's help to keep our world as clean as possible so we don't have painfulness in our lives.
