1. Chapter 1: The Nature of Science

2. Scientific Thought
Skepticism- a questioning and often doubtful attitude.
Why do we need to know this word?
Thinking like a scientist helps you solve problems and think critically about the world around you.

3. What is this creature?

4. Groups

5. What you are doing in your group.
Describe how you would evaluate the existence of the Loch Ness monster.(what scientific evidence would you look for to prove the existence? How would you collect that evidence? Etc.)
You will share your evaluation with the class.

6. Universal Scientific Laws(not facts)
Law of gravity
Law of conservation of energy
Laws of planetary motion
Apply to all branches of science and to every person.

7. Science and Ethics
Because scientific experimentation and discovery can have serious ethical implications, scientific investigations require ethical behavior.

8. Scientific Investigation
1. Make observations
2. Formulate a hypothesis
3. Design an experiment
Control- standard for comparison
Independent variable- factor that the scientist changes
Dependent variable- factor that changed due to the independent variable
Constants- factors that remain the same in an experiment

9. Scientific Experiment, cont.
4. Analyze results
5. Draw a conclusion
6. Consider bias

10. Scientific Theories
The main difference between a theory and a hypothesis is that a hypothesis is a specific, testable prediction for a limited set of conditions and a theory is an explanation for a broad range of data.

11. SI Units You must use SI units in science to have a common language.

12. What is biology? Biology is the study of life.
Includes: biochemistry, ecology, cell biology, genetics, evolutionary theory, microbiology, microbiology, botany, zoology, and physiology.

13. Evolutionary Theory Study of changes in types of organisms over time.
Remember that a scientific theory is an explanation for a broad range of data.
Because we are in a science classroom we will only discuss scientific theories.
This class is not designed to try and change your religious beliefs, but to teach you about biological principles and concepts. Your beliefs are completely your choice.

14. Properties of Life Cellular organization Homeostasis Metabolism
Responsiveness
Reproduction
Heredity
Growth

15. Cellular organization
Smallest unit capable of all life functions.
The basic structure of cells is the same in all organisms.

16. Homeostasis
All living things must maintain a stable internal environment.
When this happens, even when the external environment changes, it is called homeostasis.
(ex) body temp/sweating

17. Metabolism
The sum of all of the chemical reactions carried out in an organism.
(ex) bank account

18. Responsiveness
DUH
How have you responded to your environment today?

19. Reproduction
When an organism makes more of their own kind.

20. Heredity
The passing of genetic traits from parent to offspring.

21. Growth
All living organisms grow.
