Transcript Natural Selection Lab

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
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
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
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
Record the number of beans for each Wooleybooger

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.

and the change in allele
frequencies.
