1. The Science of Biology
Mr. Freidhoff

2. Can you solve this?

3. What is Science?
Science is an organized way of gathering and analyzing evidence about the natural world.
Science is a process, not a “thing”.
Experiment = Learning.

4. What is Science?
Science has gathered an enormous amount of information about the natural world.
Science also is an understanding what we don’t know.

5. The Scientific Method

6. “Scientific Method” Steps in solving a problem or researching a topic.
Observation
Ask Question
Form Hypothesis
Experimentation
Analyze Results
Accept Hypothesis
Reject Hypothesis

7. Scientific Method Memes

8. Hypothesis
A hypothesis is a proposed scientific explanation for a set of observations.
“Educated guess”

10. Experimentation Experiment: Includes procedure and materials used.
Controlled Experiments: An experiment where only one variable is changed at a time.

11. Variables
Independent Variable: the part of the experiment that you change.
One variable
Dependent Variables: the part of the experiment that changes as a result of the manipulation.
Scientists collect data from DV

12. A Scientific Theory
Scientific Theory: A well tested explanation that makes sense of a great variety of scientific facts and observations.
Is supported by a large body of evidence.
“It’s just a theory”
Theories can change with new evidence.
Theories never become laws.

13. Fact: objective and verifiable observation. Facts support theories.
Fact: My shirt is blue.

14. Pseudoscience
Pseudoscience: A collection of beliefs or practices mistakenly regarded as being based on scientific method.
Astrology
Alternative Medicine
Toxins

15. Chapter 1: An Introduction to Environmental Science
Mr. Freidhoff

16. Environment
Environment: includes all of the living and nonliving things which organisms interact with in a particular area.
How do you affect the environment?
Think of ways you affect your surrounds environment.
Create a list of as many of these ways as possible.

17. Renewable Resources
Naturally replenished resources that are renewed over a short period of time.
Wind
Solar
Wave Energy
Geothermal

18. Nonrenewable Resources
Naturally occurring resources formed much more slowly than we use them.
Coal
Gas
Nuclear
Petroleum
Natural Gas

19. Fossil Fuels
Nonrenewable material that is used in the production of energy.
Examples
Oil
Coal
Natural Gas

20. What does the human population look like on a graph?

21. Sustainable Living
Resources are equally used at a rate in which they are being produced.
Trees are cut down to be used for wood, paper, and other products.
Trees are replanted for future use at an equal volume.

22. Ecological Footprint
Measures how much land and water area a human population requires to live.
Land must produce the resources it consumes and to absorb its wastes under prevailing technology.

25. Discussion
Why does the United States have such a large ecological footprint?
Why do other countries have a small ecological footprint?
What can the United States and other countries do to shrink our footprint?
How are people in other parts of the world affected by the increased use of resources and the decrease in productive land?

26. Ethics Branch of philosophy that involves the study of behavior.
Good vs. bad
Right vs. wrong
Moral values held by a person or a society.
Promoting human welfare.

27. Environmental Ethics
Ethical standards within a relationship between humans and their environment.

28. Tragedy of the commons
Commons: Areas or resources that are available to everyone.
Land
When people use resources unregulated, resources can’t be replenished.
Hurts everyone using the resource.
A common area can support a small population, not a large one.

29. Tragedy of the commons
In other words, everyone acts as an independent, ignoring the group's collective interests in favour of their own.
What is E-Waste?
Electronic Waste
Describes discarded electrical or electronic devices
