Investigations in Environmental Science

Lesson Summaries, Concepts & Practices

Unit 1: Land Use

LESSON SUMMARIES CONCEPTS & PRACTICES
Chapter 1: New School  
Lesson 1: Overcrowded and Using Land Well
Students are introduced to the case of a Florida school district facing overcrowding. They receive information on the proposed site for the new school, which is home to a population of gopher tortoises.
  • Populations
  • Population Growth
  • Resources
  • Ecosystem
Chapter 2: Populations  
Lesson 1: What is a Population?
Tracking numbers in a daphnia population and gathering information about their own family history engages students in exploring population change.
  • Population Change
  • Population Growth
  • Immigration
  • Urbanization
  • Census Analysis
 
Lesson 2: Looking at Populations in ArcView
ArcView, a GIS software, allows student to explore population trends on a national and global scale.
  • Data Retrieval
  • Data/Graph Interpretation and Analysis
 
Lesson 3: Population Changes
Students interpret data from population pyramids and use global data to calculate population growth rates and predict future trends.
  • Population Growth Rate
  • Population Pyramids
  • Birth/Death Rate
  • Immigration/Emigration
  • Urbanization
 
Lesson 4: Is There a Limit?
Through reading about a population of reindeer, revisiting their daphnia data, and applying the concepts they have learned to their own lives, students explore the factors that can limit population growth.
  • Environmental Decision-Making Process
  • Closed Systems
  • Carrying Capacity
Chapter 3: Resources  
Lesson 1: Land
Students calculate the land needs in the Florida school case, examine the land resources required in their own lives, and compare their usage to the rest of the world. They compare their calculations to the amount of actual available land.
  • Arable Land
  • Carrying Capacity
  • Land Resources
  • Ecological Footprint
 
Lesson 2: Energy
WorldWatcher, an Earth science visualization and analysis program, helps students compare the air temperature predictions to actual data. Students also learn about different types of available energy and human energy consumption.
  • Energy Resources
  • Sun
  • Fossil Fuels
  • Air Temperature
 
Lesson 3: Water
Using WorldWatcher, students learn about Earth's water distribution. They also explore their own water consumption practices and determine how best to divide the water and energy resources for their community.
  • Water Resources
  • Climate
  • Biome
 
Lesson 4: The Protein Dilemma
Students look at the benefits and trade-offs of changing their source of dietary protein, while taking into consideration the effects of their decision on family, friends, the environment, and themselves.
  • Natural Resources
  • Environmental Decision-Making Process
Chapter 4: Ecosystems
Lesson 1: Animal Land Use
By reading about gopher tortoises and exploring the ways animals use land, students compare their calculations for the land needs of the school to those of the natural environment.
  • Ecosystems
  • Community
  • Habitat
  • Keystone Species
 
Lesson 2: Food Chains and Food Webs
Students investigate ecosystem relationships and how energy is transferred within the system. Construction of food webs helps students explore how changes in certain animal populations can alter the entire food chain and ecosystem.
  • Ecosystems
  • Trophic levels
  • Energy transfer in an Ecosystem
  • Food chain/Food web
  • Producers/ Consumers
  • Predator-Prey
  • Biomagnification
  • Bioaccumulation
 
Lesson 3: Interdependent Relationships
Students explore the different types of relationships that exist in ecosystems and the importance of each species to the balance and survival of the system.
  • Ecosystems
  • Relationships between organisms in an Ecosystem
Chapter 5: Case Studies  
Lesson 1: Invasive Species and Bridges and Tunnels
Using their knowledge of ecosystems, populations, and environmental decision-making, students analyze the consequences of and solutions to natural and man-made hazards to the environment.
  • Environmental Decision-Making Process
  • Invasive Species
Chapter 6: Florida School Project  
Lesson 1: Setting Up the Problem
Given their new understanding of populations, resources, ecosystems, and environmental decision-making, students reevaluate the constraints and considerations that must go into deciding on the plans for the new Florida school.
  • Populations
  • Resources
  • Ecosystems
  • Environmental Decision-Making Process
 
Lesson 2: Narrow Options
Students decide on the three best size and placement options for the school based on the constraints and considerations they developed in the previous lesson.
  • Populations
  • Resources
  • Ecosystems
  • Environmental Decision-Making Process
 
Lesson 3: Evaluate and Compare
Creating Stakeholders Charts helps students evaluate all the possible effects of their decision for the Florida school.
  • Populations
  • Resources
  • Ecosystems
  • Environmental Decision-Making Process
 
Lesson 4: Decide and Present
Students select the best option for the Florida school, assemble a report, and present their decision to the class.
  • Populations
  • Resources
  • Ecosystems
  • Environmental Decision-Making Process
