In an experiment following the scientific method, a constant is a variable that cannot be changed or is purposely not changed during the experiment. Some constants are purposeful and selected by the scientist to control an experiment while others are more universal and beyond a researcher's control.Know More
Any experiment conducted according to the scientific method will have constant variables and experimental variables. Experimental variables are those variables a scientist chooses to change so she may study the effects of the change. Constants are variables that are kept the same to ensure all effects being studied and measured are the result of an experimental variable.
If a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent to avoid invalid data. The size of the cage, amount of light, food and many other variables would need to remain constant to ensure accurate results and a valid study. Those variables are constants. Some variables are not under a scientist's control, but are still considered to be constants. These constants are called universal constants and include gravity, the speed of light and electronic charge. Universal constants do affect experiments but will be constant through an experiment without being controlled by the scientist.Learn more about Measurements
The seven steps of the scientific method are observing an occurrence or asking a question, researching the topic, forming a hypothesis, designing and conducting an experiment, analyzing results, drawing a conclusion and reporting results. Scientists utilize this method to construct effective experiments that test natural cause and effect relationships.Full Answer >
According to HowStuffWorks.com, the five steps in the scientific method are make an observation, ask a question, form a hypothesis, conduct an experiment and accept or reject the hypothesis. Various numbers of steps are sometimes used to explain the scientific method, but they all include the same ideas.Full Answer >
The five basic steps of the scientific method are: make observations, propose a hypothesis, design and perform an experiment to test the hypothesis, analyze the data to see if it supports the hypothesis and, if necessary, propose and test a new hypothesis based on these findings. The scientific method is the basic set of actions that scientists use to make new discoveries and prove theories correct or incorrect.Full Answer >
A scientific question is the second step of the scientific method, in which an experimenter asks a question that can be answered by forming a hypothesis and conducting an experiment. A scientific question should aim for an answer that verifies, explains or theorizes information.Full Answer >
