The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

In this debate I am talking about the positives and negatives of the statement,’Is it sometimes right to prevent scientific development and discovery?’ This will show my personal thoughts and opinions in which I would talk about agreeing and/or disagreeing with the statement.

Firstly,in my opinion I would say it is right to prevent this because if experiments are not done properly then there would be high cause of damages which can cause danger for anyone around the experiment being tested.Also,if we prevent this there will be no arguments about liking or disliking someone’s ideas.For example,a man called Doctor Stubbins Ffirth tried to find how people may catch the yellow fever disease.But this is an example of a failed experiment because it did not go how he expected it to.Adding onto this,if we carry on allowing people to be trying new experiments and it doesn’t go right many anonymous people won’t like it.Therefore,this will be causing people wanting to destroy the environment they live in so it causes the other people to stop trying out new experiments.

A reason why people may want to destroy the environment around them is not because of the experiments that some people are doing.Some of the reasons for this would be because it annoys them that their resources are being wasted on ‘experiments’ that the people that experiment things try and try again and if it carries on failing what are we losing? The experimenters probably don’t see or understand how much we are wasting on useless things.Therefore this would make the people that don’t want them to carry on experimenting protest over the streets to cause them to stop also causing damage around the environment they live around.

Another point to talk about would be why people do not just leave things how they were.For example,electricity was made by power first.But people just had to find ways to get electricity more easier to make by wasting materials from our land when we could have just left how to make electricity simple.

What annoys me and many more people is that they try many times like we have unlimited supplies of the resources they are experimenting with.Everything in this world has a limit we just have to get it into people’s heads so then they will finally realize how effective their ‘ideas’ and experiments do to the world and environment around us.

On the other hand,many people say we don’t look at the positives of experiments that have been used in the past to make cars,phones etc.This is a good example to stop preventing scientific experiments because many more things could be getting ready for producing.If people did not invent cars etc we would not have transport apart from walking and a lot of people will not enjoy that.This is a good example for a scientific invention.

Another point to back this side of the argument is how scientific inventions could affect our future as young learners.For example,this could help or bring down our revision and may help our exam or test results improve.But who knows what the future brings.

Who knows what the future may bring and what we can do to make it better with or without scientific inventions.Could it benefit?How would life be if we do not try and invent new inventions?If we do not try how do we know we can’t make the best inventions that exists and makes our lives easier or better.

Adding onto this technology and inventions these days do not just help us revise or help with work all the time.It also helps in hospitals and banks and general practitioners(GP).For example,in operations they use many different instruments and a new instrument is laparoscopy which is made out of high-tech and metal which is a small camera which fits inside your body to remove anything causing pain in the stomach area.Also,heart monitors were made as well from technology.

Banks use many machines to allow people to withdraw money.They also use machines to make stacks of money which then gets transferred from the bank supplier e.g. Bank Of England to many smaller banks e.g.Barclays,Santander,Natwest etc.These stacks of money are carried around by men in uniform saying ‘SECURITY’ which carry a briefcase with them to the bank/banks they deliver to.The main part about what is special from this briefcase is that if anyone apart from the manager or assistant managers try to open or break it to get money they will not be able to open it.Why?This is because it only allows certain people to open it.If anyone else tries to open it then purple dye will come out and destroy the money so therefore it is invalid to use anywhere.This is a scientific invention because it is like a trap for anyone else who tries to open it apart from bank managers etc.Also,the people may not know there’s a trap and if they try open it they will just see purple cash.

I believe it is right to prevent scientific inventions because if we do not stop this therefore we will suffer as we lose our resources if scientific inventions/experiments do not go right or the way the experimenters or scientists expect it to go.Therefore,this is why I believe the statement,’Is it right to prevent scientific inventions?’ is right and should be this way.

In the documentary that we were shown today it talked and explained a lot about weights and its history.It showed us many different shapes and sizes of weights from around the world.They also did an experiment in public to show people that size doesn’t matter.The example which they showed us with was two weights a big one and a small one.They gave it to the public and told them to see which one would seem heavier.The public were shocked to see that the big one and the small one were just about the same size,they were just roughly around 100 grams different to each other.Another example we were shown was an experiment to do with gravity.There was a weight in a special box which shows specifically how much the weight weighs.This experiment was done on ground level.The other part to this experiment was that they would put the same weight with the same box just on another place.They put this other experiment on the top of a block of high flats,which showed there was less gravity so therefore the weight was lighter.It was roughly 100 grams lighter than the weight on ground level.This was explained to us by the talk of gravity and how objects turn lighter as they are higher than ground level.This was what the documentary was showing us about.
