Observation and Hypothesis Formation are examples of __________ reasoning.
Prediction, experimentation and conclusion are examples of __________ reasoning.
If you refine your hypothesis with new data, it is called __________.
__________ lead to predictions.
__________ is a possible explanation of observations and must be tested for validity.
An experiment tests the __________.
True or false: an experiment tests many variables.
False (one variable at a time).
In order to perform a valid experiment, there must be a test group and a __________ group.
Hypotheses are (accepted/rejected) if experiments produce results inconsistent with the predictions.
More experimentally supported predictions make a hypothesis (more/less) valid.
_________ is the use of a high temperature to kill microorganisms (mainly used for foods).
Pasteur was a scientist that tested which 2 hypotheses?
Germ hypothesis and spontaneous generation hypothesis
What instrument did Pasteur use to disprove the spontaneous generation hypothesis?
What is the Germ Hypothesis?
When something becomes contaminated due to existing germs or germs in the air.
What is the spontaneous generation hypothesis?
That germs arise spontaneously.
