Learning Goal: To understand how the scientific method can be used to search for explanations of nature. The scientific method is a procedure used to search for explanations of nature. The scientific method consists of making observations, formulating hypotheses, designing and carrying out experiments, and repeating this cycle. Observations can be either quantitative or qualitative. Quantitative observations are measurements consisting of both numbers and units, such as the observation that ice melts at . In contrast, qualitative observations are observations that do not rely on numbers or units, such as the observation that water is clear. A hypothesis is a tentative explanation of the observations. The hypothesis is not necessarily …show more content…
4. Compounds are formed when atoms of more than one element combine; a given compound always has the same relative number and kind of atoms. Scientists later discovered isotopes, which showed that the second postulate was not entirely true. Consider two different compounds of carbon and oxygen: carbon dioxide, , and carbon monoxide, . The number of oxygen atoms per carbon atom in is double the number of oxygen atoms per carbon atom in . So we can predict that the mass of oxygen per gram of carbon in is double the mass of oxygen per gram of carbon in . And, in fact, if other carbon-oxygen compounds existed, we could predict small, whole-number ratios for the masses of oxygen per gram of carbon in all of them. This is exactly what John Dalton predicted for compounds using his atomic theory of matter. It came to be known as the law of multiple proportions The periodic table is a list of elements arranged by atomic number olumns in the periodic table are called groups, and the rows are called periods. Notice that the groups are labeled 1 to 18 and the periods are labeled 1 to 7. Groups 1, 2, and 13 to 18 are called the main group elements, groups 3 to 12 are the transition elements, and the bottom two rows are called the lanthanides and actinides, respectively. This table gives properties and alternate names for some of the groups: Group | Name | Properties | 1 | Alkali metals | React to form 1+ ions. | 2 | Alkaline
In this paper in will provide details on how scientific methods can be used in the Human services. Explaining the steps of scientific methods, and how it serves as an important key to Human services professionals. Each steps will be included on how they are define and what purpose it serves will scientific methods are applied. Human services professionals use the scientific methods to gain information on the client as well as how to approach the clients issues. Also researching other resources to meet the needs of the client to ensure the client is receiving accurate
There are four main characteristics of the scientific method: observation/measurements, make an assumption, test the assumption, and revise the assumption. The first stage we make an observations. For instance, I notice that my peppers in my garden are not growing well. I am going to assume this is because I did not water that area well enough. So I am now going to test my assumption. This is done by watering the peppers in my garden more frequently. Lastly, I am going to see if my assumption was correct. If my peppers only needed more water, they will begin to grow more rapidly. It is also possible that my assumption was wrong, and that my peppers were getting enough water; however, there could be something wrong with the soil, temperature, etc. These are the four main characteristics of the scientific method; it is important to note that our assumptions sometimes be wrong, thus it is always important that we test our assumptions to make sure we are correct.
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
The scientific method is a process that is used to answer questions and solve problems. Although there are different variations of the scientific method, it contains 5 basic steps. (1) Recognize a question or an unexplained occurrence in the natural world. Once this question has been developed examine scientific literature to determine what is already known about the subject matter. (2) Develop a hypothesis. A hypothesis is
The scientific method is used during experiments to find a conclusion and or reason as to why an event or something happens.
The scientific method is a process used to prove or disprove a hypothesis through experimentation and analysis. The steps necessary include Asking a question and/or observation, Forming a hypothesis, Test the hypothesis, Analyze the results, Draw a conclusion, and Publish the findings.
To support the theory of continental drift is through topography, surveying the floors of oceans, charts of rock magnetism, and statistics on rock ages (Trefil & Hazen, 2010). At one time scientist believed that the deep ocean floors were flat; accumulating the sediment that progressively wore away from the prehistoric landmasses (Trefil & Hazen, 2010). However, they discovered steep-walled valleys and elevated highlands. This was evidences that just as the continents are transformed and are active, so to is the seafloor (Trefil & Hazen, 2010). The Mid- Atlantic Ridge, positioned in the central part of the Atlantic Ocean, is recorded to be the longest mountain range on this planet. Volcanoes, lava flow, and earthquakes are a source of
The Scientific Method is the standardized procedure that scientists are supposed to follow when conducting experiments, in order to try to construct a reliable, consistent, and non-arbitrary representation of our surroundings. To follow the Scientific Method is to stick very tightly to a order of experimentation. First, the scientist must observe the phenomenon of interest. Next, the scientist must propose a hypothesis, or idea in which the experiments will be based around. Then, through repeated experimentation, the hypothesis can either be proven false or become a theory. If the hypothesis is proven to be false, the scientist must reformulate his or her ideas and come up with another hypothesis, and the experimentation begins again. This
Scientific method utilizes a series of facts, hypotheses, laws, and the theories to explain observations in the natural world. It involves observing, coming up with a hypothesis and make predictions, test those predictions and repeat to find the similar results.
Science, as a working method, employs basic principles such as objectivity and accuracy to establish a finding. It often also uses certain admitted assumptions about reality, assumptions that must eventually support themselves and be proven, or the resulting finding fails verification.
from the class “The Scientific Method and How Science Works”, I understood that scientific method is the basic of all scientific experiments, then I learned six steps of it. I also learned the difference between observation and hypothesis, which has a great contribution to my understanding of geology principles. When I see the steps of the scientific method, I think it is quite similar with the hypothesis testing model in my statistic course. It is also connected with the rejection and acceptation of the hypothesis that I have learned in the commercial courses and the similar processes are applied in the scientific method!
The scientific method, a long debated question to weather or not it accurately proves and aids in human knowledge or not. In order to have unquestionable and accurate findings, the scientific method is essential in guaranteeing accuracy. The scientific method includes imperative steps that help scientists prove whether or not a hypothesis is correct.
Scientist use the what is know as the “Scientific Method” conducting experiments and trying to discover new things. This is done using a five-step process that starts with identifying the problem or desired goal. The next step is to propose a hypothesis followed by making a prediction. The forth step is to test the prediction and the fifth and final step, is to draw a conclusion. and (Postlethwait, J., Hopson, J., 2011). During the fourth step, test the prediction, is the step that most accidental discoveries occur because this is when the scientist is in their experimental phase. It is when you set out to do one thing and the outcome is not unexpected due to a change in the desired effect. While not all accidents are good accidents, throughout
The first, and probably the most important part in the Scientific Method is observing and stating a problem. For example, one might wonder why the sky is blue during the day, and black during the night. Since our curiosity might get the better of us, we would wonder why the sky changes color, and try to find out.
“If we understand how researchers separate fact from fiction perhaps we too can avoid some of the pit falls of faulty reasoning and unwarranted conclusions in our everyday lives (Zimbardo, 2001).” I believe this is why scientists- including psychologists- think more logically rather than emotionally. They need and/or want proof of a 'phenomenon ' and so they go looking for that proof. Until they find an answer concerning that particular phenomenon, they will most likely not stop conducing experiments. This is how hypotheses are formed. Someone asks a question and then figures out the best way to get the answer to that question. It is a remarkable process. The part of that process that I will be talking about is the hypothesis.
