Transcript of AP Biology Group Presentation: Sections 1.4-1.6 Clarification 1) Natural Selection -a group of...
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)
PredictionSection 1.4
- Evolution - Chapter 22 - Darwinism - Chapter 22 - Biological species - Chapter 24 - Anatomical variations - Chapter 32 - Adaptive radiation - Chapter 23
Section 1.5 - Scientific inquiry - Starting from Chapter 7 - Data - Every chapter (NSP) - Scientific technology - Chapter 20 - Modeling cell division - Chapter 12 - Model type - Chapter 21
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
Diagram 1:
The Diagram represents a controlled experiment including two types of snakes with varying traits.
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]
