Why Do Scientists Come Up Hypotheses

There is loads we know about living things on our planet, about us walking-talking humans or the weird and wonderful creatures that swim in the seas and soar through the air but we still don’t know for sure…where it all came from! The story begins over 3,500 million years ago and ends today, with you reading this! How did life begin? It is the job of those who study life to try and figure this one out, and after many years of trying there are some brilliant ideas.

The development of the scientific method in the late 1500’s to the early 1600’s was a crucial stepping-stone in the science community. The scientific method is based upon observations, hypotheses and experimentation. The concept is rather simple, and can be applied to many areas of study. Once an observation is made, the observer can make a hypothesis as to why that phenomenon occurs and can then design an experiment to prove whether or not that hypotheses is valid. Although the scientific method has been extremely useful in the discovery of various things from usages of medications to studying animal behavior, there are still those who question the usage of this tool. These critics claim that since

We discover scientific knowledge in various natural science fields such as biology or chemistry. A common misconception about the natural sciences is that both the knowledge they reveal to us and the scientific method used in discovering this are purely analytical. This means that these sciences are rigid in facts and do not contain any subjectivity or creativity. However, the scientific method is not a rigid system of pursuing measurable facts. It contains fallacies and biases. In testing hypotheses, performing observations, or reasoning inductively, science is undoubtedly flawed and erroneous. Paradigms, commonly seen as infallible and containing rather insignificant errors, contribute to many of the errors involved in scientific

Early earth was dominated with carbon dioxide and hydrogen sulfide. Hydrogen sulfide are invisble gas that were poisonous. We think this is when life first took hold. Penny Boston and Diana Northern investigate how life can survived here. They went to a cave, Cueva day Pl lose which was filled with hydrogen sulfide. Life is thriving inside the cave. Single cell bacterias snot tights were here. Bacteria are common organism, grow adapt and reproduce. Many bacteria were found and they survive from the hydrogen sulfide. If they can find life here, then life can be formed in early earth.

1. (15pts) What could have been the students’ hypothesis? (Include specifics on what we discussed in class regarding a scientific hypothesis.)

Empirical science’s theories and knowledge should never be imposed or blindly accepted without self-exploration. Since the planet is complex and contains so much uncertainty, whenever a new theory adapts or when we accept the prior theory, scientists should always test or observe upon if the theory is compatible with the time period. Learning knowledge is a serious matter and should be never forgotten by the

It is not known how life came to be on the earth, but it is proven that it has evolved over time, and life is unified by a common ancestor. In the 1920s, a hypothesis was created by scientists Alexander Oparin and J.B.S. Haldane, that predicted that the first life forms were formed in an acidic primordial sea. Oparin believed that a string of of chemical reactions within an aquatic environment had led to the formation of coacervates. Coacervates are aggregates of organic polymers that have life like characteristics, but are not alive. When Oparin created coacervates, he used a couple different solutions of macromolecules to form these aggregates, and he discovered that the coacervates had a selectively permeable membrane.

Thought the history and as Science has developed exponentially, we the human beings have found answers through the scientific perspective to most of our reality. Although there are still, many things to be discovered and proved. One of this and most important the explanation here in this letter, is the conception of life in our planet. We can go back to any time in

They believed that organisms were formed by the molecules found in Earth’s “primordial soup”. That chemicals and an energy source had combine to form the first organisms formed in water, a pond or ocean, which was Earth’s “primordial soup.” They had concluded to this hypothesis after realizing the evolution of molecules which contained carbon. The Miller-Urey experiment was how this hypothesis was tested. By using a mixture of gases, the experiment was able to produce macromolecules, such as amino acids. Their reason was that oxygen in the atmosphere prevented reactions to occur so results wouldn’t compare to ones billions of years

science a hypothesis is always trying to be proven like Galileo was doing but it

The primordial soup hypothesis is a hypothesis that was identified by a Russian chemist named Oparin and an English genetics, Haldin in the year 1920. The hypothesis explains that life began in a pond or an ocean from a combination of chemicals from the atmosphere. The two scientists thought that that the basic building blocks of life came from a simple molecule that was formed in the atmosphere. Evidence that they used to create this hypothesis was that they observed a molecule that was energized by lightning and rain from the atmosphere that created organic soup. The reason why they had to prove their assumption was because the amino acids had to become protein in order for different gasses in the atmosphere to be contained then those used

In our lab, we discussed what a hypothesis is and how we could know if it were a valid hypothesis or if untestable. We also went over falsifiability. Falsifiability is an inherent possibility to prove it to be false. Scientific hypotheses should always be falsifiable because no scientist can be 100% sure that there are no objections to their hypothesis. We also talked about why it is incorrect to merely support and hypothesis and not to try to prove it wrong. It’s important to attempt to prove your hypothesis wrong because if you can prove it wrong then you must come up with a better, more educated hypothesis that cannot be proven wrong.

Scientists over the years have proven many things to be true and are the reason why we know so much about the world that we live in today. You would think that all theories that have once been proven to be true would stay that way but there have been a few times in history when proven theories turn out to be wrong. One theory in particular is "The discovery of Vulcan".

Urey –Miller Experiment Description of the Urey-Miller Experiment In 1953 Urey and Miller were working at a university of Chicago, directed an experiment which would alternate the method of scientific investigation into the origin of life. Urey and Miller used very basic apparatus to conduct this experiment, they used: • 2 conical flasks • glass tubing • Power supply • methane (CH4) • ammonia (NH3) • hydrogen (H2) • water (H2O) Urey and Miller gathered a closed system which he pumped a mixture of gases that were methane, ammonia and hydrogen. One of the conical flasks was half full of boiling in order to add water vapour to the mixture and the gases were circulated around the apparatus. The gases mixed together created a high voltage electrical spark and then passed through a condenser to cool it down before going through a “trap” cooled in ice to collect any liquid products.

After that theory scientists started Wondering about this theory and a lot of Scientists made up Models and conducted Experiments to Explain this Theory. In this report we will put our self’s inside Each scientist’s Shoe and see What has he discovered.
