What is a group that is altered in an experiment?
The experimental group is altered because it is affected by the experimental variable.
Why does the ambient temperature need to be measured before and after the experiment?
You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.
Which variable in an experiment is the variable expected to be affected by the manipulation?
Dependent Variable
What is the role of controls in the scientific process?
The control is there to compare the difference between it and the experiment. It should not change, but will be affected by the same environmental influences. By checking the control you can rule out environmental influences that may also have affected your experiment.
What do you mean by variables?
A variable in science is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by a scientist in the experiment. The depended variable is what you measure in the experiment and what is affected during the experiment. A controlled variable is one which the researcher holds constant (controls) during an experiment.
What is a group that is altered in an experiment?
The experimental group is altered because it is affected by the experimental variable.
Which experiment most likely has greater reliability between sunflower growth affected by hardness of the soil or water affecting the growth of cacti?
the sunflower because each experiment got the same results
How would the experimental results be affected if the flask contained moisture at the beginning of the experiment?
test it out
What is experiment set-up?
An experimental setup uses the independent variable.
What is used in an experiment to see how behavior is affected?
your eyes.
What variable is the part of the experiment that is affected by the affected variable?
i have the same thng the answer is dependent
What is a variable that is change in an experiment?
The dependent variable is the variable that can change in an experiment.
Variable is the part of the experiment that is affected by the independent variable?
Denpendent
What is the part of an experiment affected by the independent variable?
the dependent variable
What is the variable in an experiment that is affected by the independent variable?
dependent variable
What is an independent veriable?
An independent variable is a variable that is not affected by the experiment or the function. It is normally time because time passes regardless of any experiment.
