  27. The Four Big Ideas • Big Idea 1 - The process of evolution drives the diversity and unity of life • Big Idea 2 – Biological systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain homeostasis • Big Idea 3 – Living systems store, retrieve, transmit and respond to information essential to life processes • Big Idea 4 – Biological systems interact, and these systems and their interactions possess complex properties Source: http://apcentral.collegeboard.com/apc/public/repository/AP_BiologyCED_Effective_Fall_2012_lkd.pdf

  28. Hierarchy of Understanding • Big Ideas (4) • Enduring Understanding (17) • Essential Knowledge (55) • LEARNING OBJECTIVES (149)

  29. Big Idea 1 - Evolution • Enduring understanding 1.A: Change in the genetic makeup of a population over time is evolution. • Enduring understanding 1.B: Organisms are linked by lines of descent from common ancestry. • Enduring understanding 1.C: Life continues to evolve within a changing environment.

  30. Big Idea 2 – Molecular Biology • Enduring understanding 2.A: Growth, reproduction and maintenance of the organization of living systems require free energy and matter. • Enduring understanding 2.B: Growth, reproduction and dynamic homeostasis require that cells create and maintain internal environments that are different from their external environments. • Enduring understanding 2.C: Organisms use feedback mechanisms to regulate growth and reproduction, and to maintain dynamic homeostasis.

  31. Big Idea 2 – Molecular Biology • Enduring understanding 2.D: Growth and dynamic homeostasis of a biological system are influenced by changes in the system’s environment. • Enduring understanding 2.E: Many biological processes involved in growth, reproduction and dynamic homeostasis include temporal regulation and coordination.

  32. Big Idea 3 - Genetics • Enduring understanding 3.A: Heritable information provides for continuity of life. • Enduring understanding 3.B: Expression of genetic information involves cellular and molecular mechanisms. • Enduring understanding 3.C: The processing of genetic information is imperfect and is a source of genetic variation.

  33. Big Idea 3 - Genetics • Enduring understanding 3.D: Cells communicate by generating, transmitting and receiving chemical signals. • Enduring understanding 3.E: Transmission of information results in changes within and between biological systems.

  34. Big Idea 4 – Biological Systems • Enduring understanding 4.A: Interactions within biological systems lead to complex properties. • Enduring understanding 4.B: Competition and cooperation are important aspects of biological systems. • Enduring understanding 4.C: Naturally occurring diversity among and between components within biological systems affects interactions with the environment.

  35. Laboratory Exercises

  37. Overview of Labs • Student-Driven or Student-Directed • My goal: Guided Inquiry • Main drawback: Time Intensive • Overview and recommendations are provided in the “Lab Manual” • Your teacher may choose to do equivalent investigations rather than those in the “Lab Manual”

  38. Big Idea 1: Evolution • Lab 1: Artificial Selection • Follow a plant population as you select for certain traits • Quantitatively monitor the population phenotypic frequencies • Lab 2: Mathematical Modeling • Computer based quantitative simulation of population evolution or stasis utilizing Hardy-Weinberg equations • Lab 3: Comparing DNA Sequences • Use NCBI’s BLAST (Basic Local Alignment Search Tool) to investigate evolutionary relationships between provided genetic sequences

  39. Big Idea 2 • Lab 4 – Diffusion & Osmosis • Surface Area & Cell Size – gelatin & phenolphthalein • Predict relative molarities of colored solutions • Plasmolysis – plant cells in hypertonic solutions

  40. Big Idea 2 • Lab 5 – Photosynthesis • Floating disks & photosynthetic gas production

  41. Big Idea 2 • Lab 6 – Cellular Respiration • Use a microrespirometer, peas (living organism), and measure O2 consumption under different conditions

  42. Big Idea 3 • Lab 7: Cell Division (Mitosis and Meiosis) • Onion Root tip cells (Chi Square) • Visual investigation of HeLa cells • Soridaria images & Meiosis • Lab 8: Bacterial Transformation • I intend to do the old version, but update the analysis • Lab 9: Restriction Enzyme Digest of DNA & Gel Electrophoresis

  43. Big Idea 4 • Lab 10 – Energy Dynamics (I will avoid this one) • Lab 11 – Transpiration (Not on AP Exam?) • Guided Inquiry - Fruit flies & Water bottles • Lab 12 – Animal Behavior • Made for Open inquiry • Lab 13 – Peroxidase (Enzyme) Activity
