New Learning Objectives• LO 2.41: The student is able to evaluate data to show
the relationship between photosynthesis and respiration in the flow of free energy through a system (SP 5.3, 7.1).
• LO 2.42: The student is able to pose a scientific question concerning the behavioral or physiological response of an organism to a change in its environment (SP 3.1).
• LO 2.43: The student is able to connect the concept of cell communication to the functioning of the immune system (SP 7.2).

Key to New AP Courses: Focus on Skills (Science Practices) when teaching content.
Conceptual Flow Graphic• Visual Concepts are organized and displayed
• Make a display to sequence the concepts
• Display strength of relationship between concepts
• Strong Connection
• Weak Connection
• No Connection - No Arrow
Conceptual Flow Graphic
CFG Task• In small groups; you will be given concept
statements about each Big Idea
• After arranging the concept order - show the strength of relationships between concepts
• Add activities or lessons that support each concept
CFG Sharing
• Do a gallery walk and look at the other CFG’s.
• Pick 1-2 group members to stay behind and answer any questions from the different groups.

• 2015 Exam Results - Later
• Student Performance Question & Answer - “Chief Reader Report” - Later
“What can you do (science practices) to infer about what you know about Biology”

AP Exam Organization• Section 1:
63 Multiple Choice + 6 Grid-In Questions 90 minutes 50 % of exam weight
• Section 2: 8 Free Response Questions
2 long free response questions (one is lab based) 6 short free response questions
10 minutes required reading time + 80 minutes response time 50% of exam weight *Practice Exam available for AP Teachers
Sample Multiple Choice QuestionTwo flasks with identical medium containing nutrients and glucose are inoculated with yeast cells that are capable of both anaerobic and aerobic respiration. Culture 1 is then sealed to prevent fresh air from reaching the culture; culture 2 is loosely capped to permit air to reach the culture. Both flasks are periodically shaken.
Which of the following predicts which culture will contain more yeast cells after one week, and most accurately justifies that prediction?
A. Culture 1, because fresh air is toxic to yeast cells and will inhibit their growth B. Culture 1, because fermentation is a more efficient metabolic process than
cellular respiration C. Culture 2, because fresh air provides essential nitrogen nutrients to the culture D. Culture 2, because oxidative cellular respiration is a more efficient metabolic
process than fermentation
Sample Grid-in QuestionsThe data below demonstrates the frequency of tasters and non-tasters in an isolated population at Hardy-Weinberg equilibrium. The allele for non-tasters is recessive
How many of the tasters in the population are heterozygous for tasting?
Tasters Non-
Tasters
8235 4328
Sample Single Part Question The role of tRNA in the process of
translation was investigated by the addition of tRNA with attached radioactive leucine to an in vitro translation system that included mRNA and ribosomes. The results are shown by the graph.
In a short paragraph, describe how this figure justifies the claim that the role of tRNA is to carry amino acids that are then transferred from the tRNA to growing polypeptide chains

Big Idea 1: EvolutionThe process of evolution drives the diversity and unity of life
Big Idea 1: Challenge Areas• Essential Knowledge 1.A.1: Natural Selection is a major mechanism• Natural Selection
• reproductive success vs. survival success • Role of changing environment on selection (population fitness)
• Hardy Weinberg• Conditions for equilibrium • Difference between frequencies • Math skills involved in Equation • Assume the recessive phenotype must have lowest percentage frequency.
• Evidence for Evolution via Natural Selection• Using Hardy-Weinberg formula to explain evolving population
Concepts that students struggle with
Big Idea 1: Challenge Areas• Essential Knowledge 1.A.2: Natural Selection acts on phenotypic variations in populations
• Genetic Changes in Populations• How changes in genetic diversity & resulting phenotypic variation in populations can be
favorable or disruptive in relationship to particular environmental change
• How same species might present different phenotypic variation in different environment
• Variation and Fitness• Explaining mutations are random changes in genetic information • Do NOT understand how the Hardy Weinberg equation can be used to calculate allele
frequencies in a population
• Role of the Environment in Evolution• Explain how various mechanisms of evolution or other events influence allele frequencies
in populations
• Explain why genetically disadvantage traits or diseases exist since students believe evolution leads to perfection in species.
