The Scientific Method Quiz

Study Notes

The first step in the Scientific Method is observation.
A hypothesis is a testable prediction based on prior knowledge.
A controlled variable is a factor that remains constant throughout an experiment.
The experiment step involves testing the hypothesis.
After an experiment, scientists draw conclusions based on the data.
It is important to repeat experiments to ensure accuracy and reliability of results.
The conclusion summarizes the experiment, shares results, and determines whether the hypothesis was supported.
If a hypothesis is not supported, scientists should revise the hypothesis and test again.
The independent variable is the factor that is changed or manipulated in an experiment.
Peer review helps validate research and improve its quality by having other scientists examine the work.

When investigating the effect of temperature on sugar dissolving, the hypothesis could be "Higher temperatures will cause sugar to dissolve faster."
The experiment design could involve using different temperatures of water with the same amount of sugar.
Results could be analyzed by measuring how long it takes for the sugar to dissolve at each temperature.
Peer review is important because it allows for the evaluation of scientific work by experts in the field.
This helps ensure the accuracy, validity, and rigor of scientific research.
An example of peer review could be how a research paper goes through a review process by other scientists before being published in an academic journal.
