Science can be a noun and a verb.
Technology -
The knowledge and skills available to a society.
Technology has been around much longer than science.

Quantitative Observation
Explain or interpret things you observe.
Inferring (making an inference) -

Classifying -
Forming a conclusion based on observations and data.
Evaluating -

What does inquire mean?
1. Pose a Question
2. Develop a Hypothesis
3. Conduct an Experiment
4. Form a Conclusion
Possible Steps in Scientific Inquiry
Variables -
Purposely changed by the experimenter; independent variable
Manipulated Variable -
Factors that can change in an experiment.
Responding Variable - Variable the may be observed to
change in the experiment; dependent variable
Controlled Experiment -
Facts, figures, evidence gathered from the experiment.
Data -
Only one variable is changed at a time.
Graphs can help reveal patterns in data.
Conclusion -Results of what was discovered in
the experiment.
