What components should a good scientific experiment contain?

Answer 1

(1) singularity - it tests only one variable in the situation (2) reproducibility - it can be re-done by other scientists to verify the results (3) utility - the answer matters to human life in some way While most would agree with the first two elements of a "good experiment" listed above, I'm not sure you would find much consensus on the concept of "utility." Whether the result of an experiment is ultimately deemed "useful" to human life has little bearing on the methodology and scientific rigor with which an experiment is conducted. On the other hand, some would say that scientific integrity ("honesty") is a necessary ingredient in any good experiment, while others would say that a good experiment must either prove or disprove a hypothesis...which is, after all, the whole point of conducting the experiment in the first place.

Answer 2

1. Provides unbiased estimates of the factor effects and associated uncertainties
2. Enables the experimenter to detect important differences
3. Includes the plan for analysis and reporting of the results
4. Gives results that are easy to interpret
5. Permits conclusions that have wide validity
6. Shows the direction of better results
7. Is as simple as possible.
8. Your welcome

Answer 3

The dependent variable, the independent variable, and the control group.

Dependent Variable: This is the factor, or property that you measure for, or the result. It could be different between the groups, or it could be the same. You don't know the value of this variable until

the end of the experiment. This is the EFFECT property mentioned in the hypothesis. example: how high the plant grows

Independent Variable: This is the factor, or variable that you change. This is the physical property that you have direct control over to change. It should be the ONLY difference between the two groups for it to be a good experiment. It is the CAUSE property mentioned in the hypothesis. example: the amount of light.

Control Group: The group that is used as the basis for comparison. It could be: the BEFORE part of a before and after experiment (mixing two chemicals to see a color change, the control group is the setup before they were mixed). It could be: the "normal" , or it should be the group in which the value of the independent variable is zero.

example: a plant set in a room with no light bulb.

Answer 4

1) question/problem
2) research
3) Hypothesis
4)Procedure/Method (including materials)
5)Data & Results
6)Observations
7)Conclusion

those above are the components of a science experiment.

Answer 5

Two essential characteristics of a scientific experiment:

1) Intellectual honesty (it also includes giving credit to those whose works we rely upon).

2) Strictly complying with Scientific Methodology -- includes spelling out the 'assumptions' and 'limitations' in interpreting/ applying the results of our experiment, especially in the Social Sciences.

Answer 6

variable, control group, hypothese etc. blah blah blah

Answer 7

A hypothesis, a control in the experiment, a variable, and analyzing the results of your experiment, and, of course, a conclusion.
