2. Biology: The Study of Life
Chapter 1
Biology: The Study of Life

3. The Scientific Method
Designed to solve Problems with a systematic approach.
The goal is to understand the world around us.
Theory: Well tested explanation. Can be revised or replaced
Laws: has been proven to occur whenever certain conditions exist 

4. The Scientific Method
1. Purpose: Develop a question/problem that can be solved through experimentation
2. Research: Gather information
3. Hypothesis: predict a possible answer/ solution to the problem
4. Experiment: To test the hypothesis
( develop and follow procedure & include material list)
5. Analysis: Record and analyze data
(modify procedure, confirm results, tables, graphs, photos)
6. Conclusion: Include statement
(accepts or rejects hypothesis, improvements)

5. A factor that is varied by the experimenter. (manipulated variable)
Scientific Method
Independent variable
Dependent
Variable
Control
Constants
Trials
A factor that is varied by the experimenter. (manipulated variable)
The factor in an experiment that results from changes made to the independent variable ( responding variable)
Serves as the standard of comparison. No treatment group, all experiments should have a control group
All the factors of an experimenter attempts to keep the same
Replicated groups that are exposed to same conditions in an experiment

6. Controlled Experiments
involves two groups:
control group
standard by which all conditions are kept the same
experimental group
All conditions are kept the same
Only test for one condition at a time
Independent Variable/
Manipulated Variable
What is Changed
Dependent Variable/
Responding Variable
What is measured
Not all experiments are controlled (ex: field studies)

7. Scientific Method
Quantitative: Result in data, numbers and graphs
Qualitative: Descriptive, observing, and written data (letters)

8. Science and Society
Science attempts to explain how and why things happen
Science is objective: can be tested and measured
Society is dealing with the subjective Social, moral, and ethical concerns (right vs. wrong)

9. Characteristics of living things
M = metabolism: chemical reactions
Chemical processes that occur within a living organism in order to maintain life. ( Energy Production)
Homeostasis: Regulation of an Organisms internal environment: Ex. Sweating and Insulin levels
R = Respiration : Breathing
Aerobic ( with oxygen) and Anaerobic ( w/o oxygen)
How organisms take in and release gases.
S = Sensitivity: Stimulus and response
Adaptive behaviors, such as chemotaxis and Phototaxis

10. G = Growth and development
Eggs, seeds, spores, placental,
Unicellular Vs Multicellular organisms
R = Reproduction: Production of offspring
Asexual (w/o sex, Mitosis, genetically identical)
Sexual (sperm and egg, Meiosis: genetic variation)
E = Excretion: Production of waste
How organisms move waste from cells to organs
N = Nutrition: Obtain a source of food
Autotrophs: producers ex: Plants
Heterotrophs: consumers ex: Animals

11. Tissues consisting of many specialized cells
Levels organization
Cells (microscopic : Specialized, Blood cells, muscle cells, sperm cells, nerve cells)
Tissues consisting of many specialized cells
Organs a part of an organism that is typically self-contained Has a specific vital function, such as the heart.
Organ Systems a group of organs that work together
to perform one or more functions. 
Organism individual animal, plant, or single-celled life form.

12. Population (Herd of Horses)
Community (Horses, cattle, Pigs)
Ecosystems (Horses, cattle, pigs, pond, grass)
Biosphere (All of the above including atmosphere)

Questions
Create an example
for each term
1. Purpose:
( develop a question or problem)
2. Research:
( what facts do you need to look up)
3. Hypothesis:
( Predict the outcome)
4. Experiment:
(materials needed/steps performed)
5. Results:
(Will you have qualitative or quantitative or both? )
6. Conclusion:
(Compare your hypothesis with your
Results. what did you learn? )

15. Chapter 1 Questions 1. Biology : the study of life
2. Homeostasis: The regulation of an organisms internal environment (body temp and sweating. Blood glucose level and insulin)
3. Evolution: A slow/gradual throughout time.

16. 4. Dependent Variable: The factor in an experiment that results from the changes made. (Responding Variable)
5. Independent Variable: The factor in an experiment that is varied by the experimenter.(Manipulating variable)
6. Control: Serves as a standard of comparison in an experiment. The variable is left out.

17. 7. Scientific Method: The steps scientists use to
gather information and solve problems
8. Adaptation: An organism response to better survive in an environment.
(MRS. GREN)
Metabolism
Respiration
Sensitivity
Growth /Development
Reproduction
Excretion
Nutrition

18. 10. ( Must be in order)
Cells-> Tissues-> Organ -> Organ System -> Organism
11. Smell a chemical by wafting
12. Spills or breakage: most common lab accident
13. Wash your hands: The last thing you do in a lab
14. Quantitative research results in data, numbers and
graphs. Qualitative research is descriptive, observing,
and written data.

19. Regulation of an organism internal Environment.
15. Homeostasis:
Regulation of an organism internal
Environment.
Ex. Blood glucose (Sugar) levels maintained by insulin. Body temperature maintained by sweating
