Hypothesis
Observation
In science, an idea or explanation that is based on observations and that can be tested.
Hypothesis
Prediction
Experiment
Peer Group
A statement made in advance that expresses the results that will be obtained from testing a hypothesis if the hypothesis is supported; the expected outcome if a hypothesis is accurate.

The English physician Ronald Ross wanted to try to find the cause of malaria. Based on his observations, Dr. Ross suggested that the Anopheles mosquito might spread malaria from person to person. This suggestion was a

The English physician Ronald Ross knew that the parasite Plasmodium was always found in the blood of malaria patients. He thought that if the Anopheles mosquitoes were responsible for spreading malaria, then Plasmodium would be found in the mosquitoes. This idea was a

hypothesis.
scientific "truth."
A hypothesis that does not explain an observation
is known as an inaccurate forecast.
often predicts a different observation.
is rejected.
None of the above.
Scientists usually design experiments
with a good idea of the expected experimental results.
based on wild guesses.
in order to develop new laboratory tools.
All of the above.
A scientific theory
is absolutely certain.
is unchangeable
may be revised as new evidence is presented.
is a controlled experiment.
The word "theory" used in a scientific sense means
a highly tested, generally accepted principle.
a guess made with very little knowledge to support it.
an absolute scientific certainty.
None of the above.
Typically, the order in which the steps of the scientific method are applied is
