Exploring Life 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)
Prediction • Section 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.
Diagram 2: 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]
