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

Slide 32 of 46

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.

Slide 33 of 46

Slide 34 of 46

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.

Slide 35 of 46

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.

Slide 36 of 46

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.

Slide 37 of 46

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.

Slide 38 of 46

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.

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”

Slide 41 of 46

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

Slide 42 of 46

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

Slide 43 of 46

Big Idea 2

Lab 5 – Photosynthesis Floating disks & photosynthetic gas production

Slide 44 of 46

Big Idea 2

Lab 6 – Cellular Respiration Use a microrespirometer,

peas (living organism), and measure O2 consumption under different conditions

Slide 45 of 46

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

Slide 46 of 46

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
