Big Idea: Evolution(进化)
Investigation1: Artificial Selection
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
Hardy Weinberg Presentation: Count individuals and use the HW equation to determine allele frequencies.
Investigation3: Comparing DNA Sequences to Understand Evolutionary Relationships with Blast
Constructing Cladogram-drawings are used toinfer relationships and create a cladogram.
Big Idea: Cellular Processes
Investigation4:Diffusion and Osmosis
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.
Photosynthesis simulation- change light intensity and wavelength and compare the amount of ATP produced.
Cellular Respiration- modified AP lab, uses respirometers to measure oxygen consumption.
Big Idea: Genetics and Information Transfer
Investigation7:Cell Division: Mitosis and Meiosis
Modeling Chromosomal Inheritance -using beads and pipe cleaners to show how genes are passed from parents to offspring.
Investigation8: Biotechnology: Bacterial Transformation
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
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.
AP Lab - Transpiration - using seedlings and plastic bags, measure the rate at which water is lost in different conditions.
Investigation12:Fruit Fly Behavior
Isopod Behavior Lab - uses ispods(rollypollys) to investigate animal behavior.
Enzyme Lab - Using liver and hydrogen peroxide, observe enzyme actions in a variety of conditions (temperature,acidity).
