ONLY 4-function calculator (with square root) May bring up to 2 calculators Can be used throughout The Exam Source:



11 Section 1 Part A Part B 63 Multiple-Choice 6 Grid-In questions
4 answer choices Understanding and Application Answer EVERY question No point penalty for incorrect answers Part B 6 Grid-In questions Calculations Enter answers in a grid on the answer sheet This is the 1st year of the NEW AP Biology Exam. There are precious few resources for the Exam. Source:

15 (890 – 200)/2 = 345 OR (880 – 200)/2 = 340 Source:

16 Reading Period (Section II)
10 min. Questions ONLY, No response sheet Read each Free Response Question (FRQs) Determine which questions OR parts to answer first Separate into 3 categories: Clear Translucent / Moderate Unclear Source:

17 Section II Long Free-Response Short Free-Response 2 questions
Multipart (3 – 4) Time: 40 min. (20 min. per question) Short Free-Response 6 questions Time: 39 min. (6.5 min. per question) Source:


19 Free Response Review How many Short FRQs are on the AP Exam?
How long should each Short FRQ take? Which questions will be given to you during the Reading Period?

20 Free Response Review (Answers)
How many Short FRQs are on the AP Exam? 6 short FRQs 2. How long should each Short FRQ take? About 6 minutes and 30 seconds 3. Which questions will be given to you during the Reading Period? Both the 2 long FRQs and the 6 short FRQs

23 Review What does each of the 2 Sections of the AP Exam contain?
If you are not sure of an answer to a multiple choice question should you answer it? How many minutes for each long FRQ?

24 Review (Answers) What does each of the 2 Sections of the AP Exam contain? Section 1 = 63 Multiple Choice & 6 Grid-Ins If you are not sure of an answer to a multiple choice question should you answer it? Yes, since there is no point deduction for incorrect answers How many minutes for each long FRQ? About 20 minutes

30 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:

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

32 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.


34 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.

35 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.

36 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.

37 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.

38 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.

39 Laboratory Exercises

40 Source: http://media. collegeboard

41 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”

42 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

43 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

44 Big Idea 2 Lab 5 – Photosynthesis
Floating disks & photosynthetic gas production

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

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

47 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
