=Population Pressures page 525-532=
 * describe and analyze growth curves; exponential growth and logistic growth
 * identify the environmental factors that affect population growth
 * simulate the affects of predation on a population size and determine the effects of changes in each population
 * analyze information on the populations of organism that are interconnected in a northeastern forest ecosystem, and assess the factors that influence population size and, in turn, cause both Lyme disease and outbreaks of gypsy moths.


 * Driving Questions **
 * What **underlying factor**s cause natural populations of organisms in an ecosystem to increase or decrease in size?
 * What **patterns** can be discerned and what is the significance of these patterns?

Read Prologue page 525 Setting Context/ Engagement

 * How does one population influence another population?

Brainstorming page 526 Accessing Prior Learning

 * In discussion with a partner, answer the questions #1-3 in your notebook.
 * Discuss the answers as a class and aimed at population limits.

//Unsupervised// page 526-538 Activity

 * Read procedure aloud
 * Key ideas for students to articulate in their own words: **biotic potential,** characteristics of **exponential growth,** why exponential growth is rare, and **carrying capacity** (review graph on page 528)
 * Students construct the graph and answer the analysis question on page 538, #1-6; Discuss the results as a class.

//The Lynx and the Hare //pages 528-530 Activity

 * simulation activity; materials are in a bin, under the middle lab table in H104
 * Key ideas for students to articulate in their own words: **limiting factors**
 * **Student construct a** **line graph** with two lines, one for lynx and one for hare. Tape the graph into your notebook.
 * Answer analysis questions p. 530 in sentences, in your notebook.
 * Students display their graphs and discuss the causes and effects of changes in the hare/lynx populations.

//A Friendly Warning// pages 530-532 A Case Study

 * performed if time allows / Student groups continue to work on the Performance Task and gather observations of their Bottle Ecosystem
 * Read and organize the information
 * Construct a graph of your Expectations
 * Construct a Poster to Warn the Public.
