Students will know ….
TERMS:
Reproductive (Biotic) potential, limiting factors, carrying capacity

It’s important to understand that…
1. Reproductive potential is the ideal, realized potential population growth of a population.
2. Limiting factors can limit the reproductive potential of a population.

Students will be able to….
1. Distinguish between field and laboratory population studies.
2. Use computer simulations to model population dynamics.
3. Explain how limiting factors can impact population growth by interpreting data.

LESSON 1


EQ: What is reproductive potential? (also known as biotic potential)

Lab Book: Pages 27
FOSS Text: Pages 22-24

1.) Recall Exponential Growth from DOL 10.

2.) Understand that "Reproductive Potential" or "Biotic Potential" is the ideal, realized potential growth of a population under perfect conditions.

3.) Realize that humans also have "Reproductive Potential"/ "Biotic Potential" and the possibility for exponential growth.

4.) Complete page 27 (Milkweed-Bug Reproductive Potential) from your lab book.



LESSON 2

EQ: What factors limit the reproductive/biotic potential of a milkweed bug population?

Lab Book: Page 29
FOSS Text: Pages 22-24

1.) Utilize a laptop/computer to complete page 29 of your lab book.

Variables that can affect population in this simulation are:
  • Volume/space in which the milkweed bugs live
  • The Percentage of females per clutch
  • The clutch frequency (reproductive maturity of a female)
  • Number of eggs per clutch
  • Survival rate



2.) Show me your completed lab book page # 29

3.) Explore Limiting Factors






LESSON 3

EQ: What are limiting factors and how can we interpret them through graphs?

Lab Book: Pages 34-37
FOSS Text: Pages 22-24

1.) Complete lab book pages 31-33 (Milkweed-Bug Hatching Investigation) and show me your completed lab book work.

2.) Complete lab book pages 34-37 (Algae & Brine Shrimp Experiments) and show me your completed lab book work.

3.) Complete lab book pages 38-41 (Mono Lake Data) and show me your completed lab book work.

4.) Explore more on Limiting Factors



LESSON 4

EQ: What is carrying capacity and how can we interpret it through graphs?

Lab Book: Pages None
FOSS Text: Pages 22-24

1.)Complete "Carrying Capacity" packet and show me your completed work


2.) Explore Carrying Capacity

Quizlet for Pop & Eco 6


Be able to do the following:
  • Interpret or list factors that would influence reproductive potential of a population (for example: Milkweed bugs lay 20 eggs per clutch and 5 clutches in their lifetime.). (Page 29 of lab book)
  • Interpret or list influential biotic and abiotic limiting factors. (Pages 31-41 of lab book)
  • Be able to interpret population graphs and scenarios such as the graph at the bottom of the page and pages 31-41 of lab book.

Other helpful things to look at:
  • Review your note-taking sheet (Limiting Factors).
  • Review all lab sheets and homework we have had so far for investigation 6.
  • Check out Pop & Eco 6 wiki for videos & quizlet
Population Dynamics Graph
Population Graph JPG.jpg
  1. At what letter is the population having all of its needs met and few limits on its population?
  2. At what letter is the population stabilized?
  3. At what letter is the population experiencing a decline due to limiting factors.
  4. At what letter is the population at the height of its population growth?
