Conclusion:
Hypothesis:
The hypothesis made was that if a salt-water mixture is heated, then eventually the water will no longer remain and only salt will be present. This inference is supported by a few facts and the observations recorded throughout the duration of this experiment. First off, salt-water is a homogeneous mixture, meaning that the composition is uniform throughout. In addition, water is a substance that evaporates when exposed to heat and turns into steam. The water changed state from a liquid to a gas because the water reached its boiling point, while the salt was still in solid form, just as it had been in the mixture. In simpler words, salt-water can be separated through evaporation because water has a lower boiling

The class as a whole brainstormed together to come up with the materials as well. In conjunction, the class learned about the properties of certain substances, including the ones used in this lab. A few of the ones that were discussed were how iron is magnetic, the fact that salt is soluble in water, seeds contain air pockets that allow them to float, and that sand is more dense than water, causing it to sink. Using this information, the class was able to put together an efficient lab after learning about different separation methods listed above. The materials used during this lab were already provided, but some were newly introduced to the class. For example, the class learned how to set up and light a Bunsen burner, along with what a scoopula was and how it was used. Learning about these concepts and equipment during this lab will serve as an aid in future lab experiments as the class becomes more familiar with them. Overall, the purpose of this lab was accomplished because the class was able to put together a successful and efficient lab after learning about separation techniques.
Real-World:
One of the most important concepts discussed in this lab was the use of the scientific method. The scientific method is a series of steps followed to solve problems; collecting data, creating a hypothesis, testing the hypothesis and concluding the experiment. Although it is taught to be used in science-related
5. List and give a brief explanation of the steps of the scientific method. The
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.
Scientific Method: The scientific method is a method or procedure that uses precise measurements, predictions, and data to answer questions.
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 continues to be misrepresented in public schools all over the world. Students are being taught that there is a beginning and an end to the scientific method, and that everything in between is protocol and must be followed chronologically. “Ask a question, do some research, come up with a hypothesis, conduct an experiment, understand your data, make your conclusion!” a grade six science teacher will tell their students. “It’ll be on your quiz!”. However, what those students are not being taught is that the scientific method has never been, and will never be a linear process. Scientists constantly revisit different steps of the process in order to better understand the subject matter; sometimes it can take many years to
For the second part of your assignment, you will apply the scientific method to a real-life situation. You will select a problem that leads to a testable question, similar to the scenarios presented in Part I and explain how you would follow each step of the scientific method to try and answer the question or solve the problem. Note: you are describing only what you would do at each step; you will not be conducting the experiment.
After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water?
A) scientific process: The scientific process, also known as the scientific method is an organized way to help answer a question or to a hypothesis. The method includes six steps; make a conclusion, form a question, construct a hypothesis, test the hypothesis, analyze the data, and finally draw a conclusion, these steps can be modified once the process has been run through at least once for the same experiment.
The Scientific Method is the approach that scientists use to investigate some phenomena. It’s a standard technique to find cause and effect of a particular problem.
SCIENTIFIC PROCESS- the scientific process is a way to make sure that your experiment can give a good answer to your question. We use observations, hypotheses, predictions, experimentation, and conclusions.
The scientific method is the set of procedures that enable scientists and researchers to conduct
In the movie “Spare Parts” many things involving scientific method happened . . There are eight steps in scientific method . One and two are identifying problems and researching . Three and four are forming a hypothesis and planning experiments . There is also five and six which are performing the experiment and analyzing the data . Seven and eight are forming a conclusion and communicating results . In the next four paragraphs you will be learning what these are and what they do with scientific method .
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
