Natural Selection of the Wooleybooger Lab

1
Natural Selection of the Wooleybooger Lab

• Intro
• On a distant planet there exists 4 species of a
  creature called a Woolybooger
• The 4 different species include
• Clothespinmouth
• Tweezermouth
• Spoonmouth
• Knifemouth
• Each of you will play the part of a wooleybooger
  on this planet

2
Hypothesis

• State your hypothesis
• Include your reasoning why you think that way
• Purpose/problem
• List Materials
• The 4 different species include
• Clothespinmouth
• Knifemouth
• Spoonmouth
• Tweezermouth

3
Procedure

• You will run through 5 trials (generations)
• Each trial will require your woolybooger to gain
  at least 20 beans (put the beans back after every
  trial)
• If 20 beans are not acquired during the time
  period, your woolybooger has died
• When you die, you may be reborn as the
  son/daughter of an existing woolybooger (choose a
  new mouth)
• Record the number of wooleyboogers that survived
  on your data chart

4
Data table

• Data Table should include the following
• 5 generations
• Total survived Clothespinmouths
• Total survived Tweezermouths
• Total survived Spoonmouths
• Total survived Knifemouths
• Total the number of each Wooleybooger that
  survived after each generation

Post Lab Questions

• 1. How do populations change over time based
• on adaptations? Use examples and ideas
• from the lab to develop your conclusion.
• 2. Use the following terms in one paragraph to
  explain Natural Selection of the Wooleybooger.
• Natural selection, Fitness, adaptation,
  survival
• of the fittest, struggle for existence
• 3. Construct a BAR graph to show the change in
  population over time.

Selection

• Develop three graphs that represent selection and
  the change in allele frequencies.
• Use the genotypes to the left.
• Directional
• Stabilizing
• Disruptive

• Wooleyboogers
• WW homozygous dominant
• Ww Heterozygous dominant
• Ww homozygous recessive
