AP Biology Labs


Big Idea: Evolution(进化)

Investigation1:  Artificial Selection
(人工选择和自然选择及选择的类型)


Evolution Lab- simulation showing how organisms evolve over time  in response to environmental conditions


Natural Selection- another simulation showing wolf and rabbit  populations


Sex and Single Guppy- simulation that examines sexual selection


Investigation2:  Mathematical Modeling
(哈迪-温伯格平衡-稳定种群的特征)


Hardy Weinberg Presentation: Count individuals and use the HW equation to determine allele frequencies.


Investigation3: Comparing DNA Sequences to Understand Evolutionary Relationships with Blast
(进化的证据:DNA序列的对比)


Constructing Cladogram-drawings are used toinfer relationships and create a cladogram.


Big Idea: Cellular Processes
(细胞的运动过程和能量变化过程)


Investigation4:Diffusion and Osmosis
(扩散和渗透)


Diffusion and Osmosis-a modified version of the lab, measure mass change in sucrose dialysis tubes and calculate water potential.


Diffusion Lab-very simple observation lab that shows the movement of iodine through a bag, using cornstarch as an indicator.


Investigation5: Photosynthesis
(光合作用)


Photosynthesis simulation- change light intensity and wavelength and compare the amount of ATP produced.


Investigation6:Cellular respiration
(细胞呼吸作用)


Cellular Respiration- modified AP lab, uses respirometers to measure oxygen consumption.



Big Idea: Genetics and Information Transfer
(细胞遗传物质的转移)

Investigation7:Cell Division: Mitosis and Meiosis
(细胞分裂:有丝分裂和减数分裂)


Modeling Chromosomal Inheritance -using beads and pipe cleaners to show how genes are passed from parents to offspring.


Investigation8: Biotechnology: Bacterial Transformation
(生物工程)


Recombinant DNA Simulation - using paper to model how restriction enzymes can be used to modify DNA


Investigation9: Biotechnology: restriction Enzyme Analysis of DNA


DMD Electrophoresis Lab - uses electrophoresis to analyze DNA samples from a family to determine who are carries of duchenne muscular dystrophy



Big Idea: Interactions

Investigation10:Energy Dynamics
(生物的能量流动)


Build an Ecosystem - grown plants and snails in jars and record changes in levelsof CO2 by using BTB as an indicator.

Virtual Lab:Population Biology - observe the competitive exclusion principle in populations of paramecium.


Investigation11: Transpiration
 (植物的蒸腾作用)


AP Lab - Transpiration - using seedlings and plastic bags, measure the rate at which water is lost in different conditions.


Investigation12:Fruit Fly Behavior
(遗传-果蝇实验)


Isopod Behavior Lab - uses ispods(rollypollys) to investigate animal behavior.


Investigation13:Enzyme Activity
(酶的催化作用)


Enzyme Lab - Using liver and hydrogen peroxide, observe enzyme actions in a variety of conditions (temperature,acidity).
