THE SCIENTIFIC METHOD
The scientific method
3. Propose a hypothesis:
Hypothesis is a potential answer to the question, one that can somehow be tested
-
5. Test the predictions:
To test the hypothesis, we need to make an observation or perform an experiment associated with the prediction.
-
-
6. Iterate:
The last step of the scientific method is to reflect on our results and use them to guide our next steps.
If the hypothesis was supported, we might do additional tests to confirm it, or revise it to be more specific.
If the hypothesis was not supported, we would come up with a new hypothesis.
At the core of biology and other sciences lies a problem-solving approach called the scientific method.
Conclusions:
In most cases, the scientific method is an iterative process. In other words, it's a cycle rather than a straight line. The result of one go-round becomes feedback that improves the next round of question asking. Even though we show the scientific method as a series of steps, keep in mind that new information or thinking might cause a scientist to back up and repeat steps at any point during the process
Introduction
A biology investigation usually starts with an observation—that is, something that catches the biologist’s attention. How do biologists follow up on these observations? How canyoufollow up on your own observations of the natural world? Let’swalk through thescientificmethod, a logical problem-solving approach used by biologists and many other scientists..
The scientific method is used in all sciences—including chemistry, physics, geology, and psychology. The scientists in these fields ask different questions and perform different tests. However, they use the same core approach to find answers that are logical and supported by evidence.
Example:
Anthrax contagion
Robert Koch was a German physician who lived in the second half of the 19th and early 20th centuries.
Experiment: Scientists often have to invent their own experimental methods, especially when approaching an area of knowledge that has not yet been explored. Koch developed his own methods for purifying bacillus from blood samples and croping it.
Result of discoveries: Bacilli cannot survive outside a host (partially refuted hypothesis). However, bacilli create endospores that do survive outside a host and are able to cause the disease.
-
Koch's research had multiple consequences on the scientific community. But in addition his methods used in anthrax research were subsequently perfected for the study of tuberculosis and cholera. All these methods are still in use today.
Another thing he observed were inexplicable anthrax outbreaks in places where there was no individual with anthrax.
Conclusions. Through his work based on the scientific method, he reached the following conclusions, which today remain in force and govern any bacteriological research:
-In case of disease, a microbe is present.
-The microbe can be taken from the host and develop independently (culture).
-The disease can occur by introducing pure culture of the microbe into a healthy experimental host.
-The same microbe may be identified in the infected host.
When we talk about a scientist, his observations are not only from the world around him but also from the discoveries of other scientists. Thus, Koch first part of Casimir Davaine's demonstration that anthrax bacillus was transmitted directly between cows.
