1. Science of Biology

2. Goal To investigate and understand the natural world
To explain the events in the natural world
Use the explanations to make useful predictions

3. Scientists
To accomplish goal
observes
gathers data
makes inferences
logical interpretation based on prior knowledge

4. PROPOSED scientific explanation
Hypothesis
PROPOSED scientific explanation
testable
To help create observations

5. Always changing with new discoveries, technologies, observations
Science
NOT a set of truths
Always changing with new discoveries, technologies, observations

6. Scientists
Continues to ask questions
Forms hypothesis
Runs experiments

7. Control Group
Controlled experiment
no factors are changed
Need to compare it to other factors
Factors = variables

8. Experimental Group Manipulated variables factor that is changed
ONE factor for every experiment
Independent variable
scientists chooses the factor

9. Experimental Group Responding Variable
result of the manipulated variable
How does the changed factor affect the experiment
Dependent variable

10. Scientist
Record and analyze data
Draw a conclusion based on evidence

11. Science NOT ABSOLUTE TRUTH Adding evidence Refute the current evidence
More evidence helps hypothesis become theories

12. In groups of 3, create a concept map of the “Characteristics of Living Things”

13. Characteristic of living things
1-2 paraphrase as to what it means
Create a drawing
