AP Biology Group Presentation: Sections 1.4-1.6

Clarification 1) Natural Selection

-a group of organisms divide into two groups; each live in different areas  and each have differences such as reproduction and hereditary traits;  overtime they adapt to the area they live in (p.16)

2) Concept of "descent with modification“ -basically means all mammals came from a   common ancestor and overtime we split into  different species because of natural selection(P.17)

3) Discovery Science -uses observation and data to describe natural structures and  processes(p.19)

4) Inductive Reasoning - where an experimental group is compared to a control group(p.23)

5) Control Group - a group that varies only in the factor being tested(p.24)

6) Inductive Reasoning - conclusions based on observations(p.20)

7) Theory - a big explanation that has many hypotheses and has lots of evidence(p.24)

8) Requirements of Scientific Inquiry - hypotheses must be testable and falsifiable and observations and experimental results must be

repeatable(p.24) 9) Scientific Inquiry

-using science to find information and explanation(p.21) 10) Hypothesis

-an educated guess(p.20)

Summary Charles Robert Darwin   -Proposed theory of natural selection Scientific Inquiry    -Discovery science (describing nature)   -Hypothesis-based science (explaining nature) Controlled experiment   -King /Coral snake experiment -Brown snakes Importance of science and technology to

society -Improving human society to make living easier

The diagram represents Darwin’s Idea of natural selection.

Questions Evaluate Darwin’s idea of

“Descent with modification” when applied to the relation of bats and humans [1.4]

Create a plan using hypothesis based inquiry to solve the following problem: You are on a camping trip and your flashlight will not turn on [1.5]

Design a basic outline for a controlled experiment [1.5]

How does the combination of science and technology impact society? [1.6]

Choose 3 different types of animals, describe what similarities they have that would lead scientists to believe in the idea of evolution. [1.4]

How do environmental changes effect a population? [1.4]

Provide an example of qualitative data [1.5]

Develop a hypothesis for the following question: “How does acid precipitation affect trees?” [1.5]

Provide an example of Adaptive radiation [1.4]

What are some possible reasons for several different types of animals with very similar traits appearing throughout completely different areas of the world? [1.4-1.5]
