Someone who uses the processes of science to find answers about how and why things work…
…in the world.
…in the observable universe.
Life on an Ocean Planet
Chapter 1 Pages 1-3

4. The Scientist in You
This is what makes science an adventure full of discovery and wonder.
Science isn’t simply a body of facts, but the way you analyze those facts.
Doing this analysis is called the “scientific process” and when you use it, you are a scientist.

Chapter 1 Pages 1-3

5. The Ocean Planet
The ocean produces two influences vital to life on Earth.
Weather and world climate patterns dictate how warm, cold, wet, or dry it will be.
Where humans live on land
is mostly determined by the ocean.
In addition, the ocean provides three important resources: Food • Oxygen • Natural Resources (such as oil)

Historical Nature of Science – understanding how science evolved as a discipline.
Defining Your Study
Chapter 1 Pages 1–13 to 1-15

17. Studying Science Itself
Situatedness is the explanation of when, where, and why a concept came about. It is important to marine scientists because in oceanography, they may apply established scientific concepts that they will never personally demonstrate or observe. Situatedness gives scientists some basis for judging the validity of scientific concepts.
Defining Your Study

23. Science - A Definition
Science is a body of knowledge and an organized method used to gain knowledge about the observable universe.
Science, Technology, Society , and You
Chapter 1 Pages 1–19

24. Technology – A Benefit and a Burden
A technology is a material system that produces intended results or in a general sense, knowledge of those systems.
Technology has both improved and threatened daily life.
Benefit – health care, transportation, communication, agriculture and exploration.
Burden – issues such as pollution spills and overfishing.
Science, Technology, Society , and You
Chapter 1 Pages 1–19 to 1–21

25. Technology – A Benefit and a Burden
There are three broad actions that society can take with respect to the effects of science and technology on the environment:
1. Consider the environment a lost cause and disregard the effects.
2. Dismiss the effect as overstated by scientists and inconsequential.
3. Prioritize the consequences in developing and applying technologies.
Without a doubt, the last broad action appears the most logical.
Science, Technology, Society , and You
Chapter 1 Pages 1–19 to 1–21

26. The Scientific Method
The formal, organized steps scientists follow in proposing explanations for their observations and then testing their explanations are called the scientific method.
When you apply the scientific method, you apply scientific process skills (identifying the problem, classifying data, communicating findings, interpreting measurements, predicting outcomes, and recording data).
Science, Technology, Society, and You
Chapter 1 Pages 1–22 to 1–31

27. The Five Basic Steps to the
The Scientific Method
The Five Basic Steps to the
scientific method include:
1. Identify the problem (or question).
2. Make a hypothesis – making an educated guess you can test about the answer.
You use inductive reasoning to propose a process that explains the facts you observe.
You use deductive reasoning to propose what you would observe should a known process take place.
Science, Technology, Society, and You
Chapter 1 Pages 1–22 to 1–31

28. The Five Basic Steps to the
The Scientific Method
The Five Basic Steps to the
scientific method include:
3. Test the hypothesis.
4. Interpret and analyze results – if the data supports your hypothesis, you have a theory.
5. Report results, procedures and conclusions.
Reporting results is important because it allows other scientists to verify your work and conclusions, and it allows other scientists to build on what you’ve learned.
Science, Technology, Society, and You
Chapter 1 Pages 1–22 to 1–31

29. The Progress of Science
Because science is a process, it changes.
Science progresses through the revision of theories in the light of new evidence or better explanations of existing evidence.
Just because someone proposes a new theory and new evidence, it does not mean things change overnight.
Scientific progress also has social and scientific influences. Often, it takes acceptance by prominent scientists with noted credibility before the new theory replaces the old.
