Teacher Notes for Biodiversity Lab


  1. For this lab, I made a copy of the Three Study Sites blackline master (attached) for each group.
  2. I laminated the pages and cut out the individual leaves for each site.
  3. I placed the leaves for each site in a Ziploc snack bag labeled with the site number.
  4. This way, each group had three Baggies, one for each site.

(Word doc version with tables included)

Lab: Biodiversity Names:


Problem: Which tree site has the greatest biodiversity?
Experiment:
Materials:
Leaf pictures from sites
Calculator
Procedure:
    1. Count the number of species of each tree and record it in the data table.
    2. Calculate the relative abundance of each species and enter it in the data table.

Numbe r of individuals of a species

Relative Abundance = total number of individuals
3. Make a bar graph for each site showing the relative abundance of each species.
x-axis, list the species (oak, hickory, etc.)
y-axis, list the relative abundance (0.0, 0.1, 0.2, 0.3, etc.)
Data:

Site 1



Tree Species

White Pine

Maple

Locust

Number of Trees




Relative Abundance





Site 2


Tree Species

White Pine

Maple

Locust

Number of Trees




Relative Abundance





Site 3


Tree Species

White Pine

Maple

Locust

Number of Trees




Relative Abundance

















Conclusion:

  1. What is the meaning of the word “biodiversity”?



  1. Which site has the greatest species diversity? What made you pick that site?

Conclusion:

  1. What is the meaning of the word “biodiversity”? Biodiversity is the variety of life in an area
  2. Which site has the greatest species diversity? Site 3 What made you pick that site? The relative abundance of all 3 species is similar.
