WHAT IS SCIENCE?
Latin word “scientia,” meaning knowledge
Is a process of constructing, organizing, and testing explanations and predictions about the world around us.

2. ORIGIN
Originally considered a philosophy, or an investigation of everyday problems
Used by early hominids and humans to survive the day to day, any ideas how?
Science thrives on scaffolding, using what you know to figure out what you do not know.

3. pro et contra “for and against”
What are the advantages of using science?
Why?
What are the disadvantages?

4. Science in the Classroom
Why is the study of science vital to your success in this classroom, the work place, and in everyday situations?
Is science or the scientific process a learned or “innate” behavior?

5. SCIENCE 101 You must use a scientific method!
What is a scientific method?
A scientific method is a technique for acquiring, investigating, correcting and integrating knowledge

6. Scientific Method Observation Problem Hypothesis Experiment Data

Problem – what seems to be the problem? Issue? Question? Interest?

10. O.P.H.E.D.A.C
Hypothesis – proposed explanation of observed problem based on what you know.

11. O.P.H.E.D.A.C
Experiment – a test or procedure that will challenge your hypothesis in regards to your observed problem.
Accept / Support
Reject / Challenge

12. O.P.H.E.D.A.C
Data – collected information from an experiment to test a hypothesis about a problem that was observed.
Once data has been collected it CANNOT be changed or altered. Why?
What are some examples of data that you might collect tagging animals?

13. O.P.H.E.D.A.C
Analysis – a detailed examination or investigation of data with the intent of interpretation.

14. O.P.H.E.D.A.C
Conclusion – a well-structured outcome or result using the analysis of the collected data which supports or rejects the hypothesis.
A rejected hypothesis is extremely important, knowing what something is not can help you discover what something is.

15. Scientific Experiment
Utilizes a scientific method, O.P.H.E.D.A.C
Tests a hypothesis made from an observed problem.
Experiments need to be designed so they can be repeated. Why?
The more tests/experiments performed the better the results. Why?

16. Experimental Design Variables – liable to change, changeable.
Independent Variable (IV) - the variable that is changed, “input”
Dependent Variable (DV) – the variable that changes because of the IV, “output”
Control – used for comparison, shows “change”
Constant – a fixed variable that is not changed.

17. General Science Science uses a “standard” language. Why?

28. Earth Science
Utilizes a wide range of scientific disciplines to examine the Earth and its’ processes, examples?
What exactly will we be studying?

29. Earth Science There are four major areas Astronomy Meteorology Geology
Oceanography

30. Astronomy Study of objects beyond the Earth’s atmosphere
What would you study?
What is the appropriate title for a scientist who studies Astronomy?
Astronomer, “astro” relating to celestial bodies
NOT ASTROLOGY!!!

31. Meteorology Study of the air and gaseous space surrounding the Earth
What would you study?

Environmental Science does not have an agenda!
Environmental Scientists study the conditions, factors, and states of an environment
Environmentalism has an agenda!
Concerned with a personal opinion or preference for the environment, “tree hugger”
