I. The Nature of Science
·
Science
What is known about the universe
The method of finding something out
·Observations using senses
Scientific fact many can
agree using senses
Equipment used to extend the
range of senses
Temperature
thermometer
Radiation Geiger
counter
Small objects
microscopes
Ex:
Air
Indirect evidence
· Applies to physical problems
Ex:

· Science gives us the data. It is up to us to apply the knowledge. Moral decisions can be aided by scientific
information

· Observations use senses to establish
scientific fact
2. Research what have others done
3.
Hypothesis- educated guess
· Null hypothesis stated in a negative fashion.
4.
Experiment
· Control stays the same. Compare back to the control.
· Variable
independent:

dependent: changes
with any difference in the independent variable
5. Gather data - results
·Qualitative:
Describes quality.
·Quantitative:
measures amount of quantity.
6.Analyze data - Discussion
· Accept or Reject your hypothesis
·Explain why you got the results you did.
·Discussion, not necessarily a conclusion.
7. Repeatability others should be able
to repeat your experiment and get similar results
8. Share your findings with others
