1. The Science of Biology

2. What is Biology?
Biology is the study of living organisms and their interactions with each other and their environment.

3. It includes general truths or laws It applies the scientific method
It is considered a “natural science”
Relies on quantitative data

4. Scientific Reasoning Inductive
Uses related observations to arrive at a conclusion
May be quantitative or qualitative
Scientist infers based on evidence (induction)
Used in descriptive science (discovery)
Goes from specific to general

5. Deductive Hypothesis based
Uses a general principle or law to predict results
Begins with a question or problem and a potential answer that can be tested
Goes from general to specific

6. What is the next number in the sequence 6, 13, 20, 27,…
All math teachers are over 7 feet tall.
Mr. D. is a math teacher.
Therefore, Mr. D is over 7 feet tall.

7. Basic vs. Applied Science
Basic is pure science, it is designed to gain knowledge whether or not it may be useful.
Applied science tries to use science to solve a problem….
technology

9. The Scientific Method
Start with a question or problem about an observation
Propose a hypothesis-an explanation that can be tested
Should be falsifiable (disproven)
Science doesn’t prove things are true because we are always learning more and understanding changes

10. Experiment Designed to eliminate the hypothesis
Variable-part of the experiment that changes
Control group remains the same in all ways-does not contain the variable being tested

11. The Diversity of Life
Evolution is the source of the diversity of life on our planet.
Gradual changes form new species from old ones.
This means living things show relationships to each other.
Shown in phylogenetic tree

13. Branches of Biology
Molecular / biochemical biology studies processes at those levels (DNA, RNA, Proteins)

14. Microbiology studies single celled organisms

15. Zoology-animals (ornithology, primatology, ichthyology)

16. Botany-plants

17. Human-specializes in specific systems such as neurobiology, anatomy, developmental, immunology, genetics
