The summary of the main idea of this article

  • A banana lover from Brazil discovered that banana peels can purify water and can be reused eleven times. The only con about this is that it doesn’t kill bacteria.


The Science used in the article :

Brazilian environmental scientist Gustavo Castro tests revealed the presence of nitrogen, sulfur and most importantly, organic compounds like carboxylic acids, that have the capability of binding with metals that they come in contact with.

Also, To experiment if the acids in the peels would be effective in polluted water, Castro and some colleagues dried and minced some banana peels and added them to jars of water obtained from Brazil’s Panama River, which is known to contain copper and lead. They also built filters by compressing the peels and then pushed water through them.


How the science used in this can affect the world :

The science used in this discovery can affect the world economically, for example when you need to buy a new filter for your sink, you have to go to the electronic store or some sort of store and buy a really expensive water filter but you might not want to waste money on such thing if there is a cheaper and a better way of doing it. People can save lots of money just buying 3 packs of 5 bananas and it will only cost less than 10 dollars which is quite cheap and can save a lot of money although there still is a problem science cannot solve where bananas can’t remove bacterias.


is this science is beneficial or harmful to people and the planet?

Overall, the science used here is not harmful to the planet at all since it is part of a delicious fruit that everyone likes and definately is a benefit from buying this because it never takes up so much space in your house and will save money, time and energy.

Science class mini research project

In science class we did a mini research project on different metals. I got chosen to research the metal “Palladium”.

What did I learn?

I learned that palladium is a very useful metal in your life and should keep producing it. Palladium is used in ground water treatments, jewellery and most importantly fuel cells to convert fuel to electricity and catalytic converters in the car exhaust pipes to prevent toxic gas from coming directly out of the pipes.

What can I improve?

The one thing I really need to improve on is siting all the sources I used, so form next time I will definitely put it in MLA format and site it on the sheet.

About stereotype

What does stereotype mean?

A stereotype is when you group a type of race or individuals together and make a judgement about them without knowing them well enough to make a comment about them for example, men, women, skin colors and culture.

When are stereotypes useful?

I don’t think stereotypes are useful because there are generally negative, for example “all asians can do math” isn’t really a positive thing because anyone can do math and thats not the only thing asians can do. It makes it sound like it’s the only thing they can do.

Can you judge a book by it’s cover?

No. Not at all, though it really depends sometimes you can but sometimes you can’t, but most of the time you can’t judge a book by just looking at the cover.
