Scientific Method

The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

What is the next step if the data from an investigation does not support the original hypothesis?

If the data from an investigation does not support the original hypothesis then either:

  • The method of investigation may be flawed and may need to be changed and repeated.
  • The interpretation of the data may be incorrect and should be reviewed.
  • The hypothesis needs to be reevaluated to possibly conform to the data.

Which step of the scientific involves obtaining information through the senses?

A step in the scientific method that requires you to use your senses to obtain information is the making an observation step.

How did Lorenzo's parents use the scientific method to solve their problem?

The Odone parents both became scientists out of desperation. First, Lorenzo's parents started by learning all they could about the disease. They read all the available studies on the topic, and even read beyond ALD-specific studies to learn about other experiments. Their proposed hypothesis was that using a modified olive oil would reduce the fats in Lorenzo's blood. They tested it by feeding him the oil at regular intervals. They kept careful notes on the fluctuation of his triglyceride levels. However, it did not work completely, and they had to restart the process. They then realized that there was just one enzyme working on the long chain fatty acids, and that this caused the oil to be ineffective. For the oil to be effective, it had to occupy the short chain fatty acids as well. Through more studying, they found that adding rapeseed oil would occupy the short chain fatty acids as well. Once again, they tested and kept close notation on the triglyceride levels. This time, they got the serum correct, and got positive results.

change it up though! lol i dont know who you are, and i have the exact same set of questions i think, so theres a chance you might be someone i know. just in case, change it up.

Why should you leave the Bunsen burner with the air hole closed?

Because if the air hole was wide open, the flame will be blue, which is going to be really hot so you have to leave it at a safety yellow flame which is when the air hole is closed when lit. It could be dangerous to leave a Bunsen burner on a blue flame.

this is confusing, explain more clearly, geez is dat too much to ask?

What was the first scientific step used by Zadock Thompson research the mysterious skeleton?

The first scientific step used by Zadock Thompson in researching the mysterious skeleton was observation. Zadock observed a whale's skeleton.

What is the 'sample' in and experiment?

A group selected from a population for observation in a study.

That definition comes directly from the glossary in my research in education textbook. In other words, I think you want to define the people in the study.

What is a psychologists method for testing a theory?

A psychologist would use the scientific method to test a theory, just as any other scientist would.

What is a substantive theory?

A substantive theory may be constructed within the process of identifying differences and similarities of contextualized instances, and patterns, across and within case studies focused on a similar theme. The content of substantive theory is mainly descriptive, focused on the essence, or substance, of the numerous case instances in a parsimonious relational structure.

Why can you not draw a conclusion about the effect of one variable - in an investigation when the other key variables are not controlled?

Because there is no way to know what effects the other key variables are having on outcome. So, there is no way to evaluate any one variable, or its effects on outcome.

Real life examples of scientific notation?

i found this on the internet:

Scientific notation is needed any time you need to express a number that is very big or very small. Suppose for example you wanted to figure out how many drops of water were in a river 12 km long, 270 m wide, and 38 m deep (assuming one drop is one millilitre). It's much more compact and meaningful to write the answer as roughly 1.23x10 to the 14th power than it is to write 123120000000000.

What is the unit for a time squared vs distance squared graph?

There's no such thing as "the unit" for a graph. Each axis has a unit, and you've

stated both of them in your question: One axis is marked in units of (time)2, and

the other is marked in units of (distance)2 . We fail to comprehend the physical

significance or applicability of such a graph, but if it somehow suits your needs,

then knock yourself out. We note that the slope of the graph works out to units

of (speed)2 , so maybe it has something to do with kinetic energy perhaps ? ?

What is the difference between forming a hypothesis and testing a hypothesis?

forming a hypothesis is when you come up with an educated guess.. what you think it may be .

testing a hypothesis is when you're testing to see if someone else's guess is right.
