Scientific Method
Step 1 - Before we can have an answer, we have to know the...
Question / Problem
To measure time you would use a:
clock/timer/stop watch
Quantitative Observation
Observations based on measurements with UNITS
Theory:
well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
The last step in the scientific method:
Conclusion
Step 3 - What do we need for our experiment / test
Materials
To measure volume you would use a:
Graduated Cylinder
Qualitative Observations
observations based on your senses
Dependent Variable:
the variable that changes as a result of the independent variable
You would use a microscope to measure
very small things
Step 4 - How are we going to do the experiment
Procedure
What does a thermometer measure?
Temperature
Opinion:
non-testable "belief"
Law
A phenomenon of nature that has been proven to happen in certain circumstances under specific conditions
You would use a telescope to measure:
very far away things
Step 5 (The Last Step)
Conclusion
You would use a ruler to measure:
Distance
Control
part of the experiment that is unchanged for the purpose of comparison.
parts of an experiment that are kept the same throughout the experiment
Constants
Variable that changes based on the independent variable
Dependent Variable
Step 2 - What we think is going to happen based on research
Hypothesis
A triple beam balance measures:
Mass
Independent Variable
The variable changed by the tester
Data
Information obtained through experiment or observation
You would measure air pressure with:
A Barometer
