Additional Case Studies: Materials Contributed by Teachers

Here you will find lesson plans, activities and other materials created by educators, and which apply the Ecology Disrupted pedagogical strategy—using the environmental impacts of everyday human behavior to illuminate ecological principles.

More materials will be added, and more descriptive information about the materials will be added to help educators find what's most useful to them.

If you have lesson plans or other curriculum materials created from the Ecology Disrupted materials that you would like to share with other educators, please send them to Dr. Yael Wyner.

Data Analysis Activities

This section contains data analysis worksheets created by teachers. Use them as data analysis assessments or to illustrate ecological functions.

Hantavirus and Human Health
How does human-caused habitat loss unintentionally lead to human health threats by reducing community biodiversity?
Data Format: Bar and Line Graphs
Keywords: Habitat, Community, Biodiversity, Human Health

Hantavirus is a rodent borne disease of the heart and lungs that is very deadly when passed onto people. Since some rodent species are more efficient carriers of the virus, scientists thought that the reduced biodiversity brought on by forest loss may increase the prevalence of the disease. To test this hypothesis, scientists compared the prevalence of hantavirus in rodents in forest plots that they manipulated to have few rodent species (experimental) to forest plots that they did not touch, i.e. with many rodent species (control). The data presented in the two graphs the students analyze demonstrate their findings.

Algae Diversity and Clean Water
How does algae species diversity reduce water nitrogen levels and contribute to clean water?
Data Format: Line Graph
Keywords: Biodiversity, Nitrogen Cycle

Recently scientists conducted a lab study that showed that a more biodiverse community of algae is more efficient at removing excess nutrients from water. Changing stream environments can make streams less hospitable to some algae species, leading to fewer algal species that are less efficient at removing excess nutrients.

White Nose Syndrome

White Nose Syndrome and Bats
How does an invasive parasite disrupt predator-prey relationships?
Data Format: Maps
Keywords: predator/prey, ecosystem disruption

A new fungus has been spotted that is harming bats. Bats with this white fungus on their noses show uncharacteristic winter behavior. Normally, bats hibernate in winter to survive the season when very little food is present. Bats with this fungus have been found flying during the day and during winter. They also have low body fat, making survival difficult. It seems to be responsible for declining bat populations across the United States.

Acid Rain

Acid Rain
How does burning coal affect the rain acidity in the Northeast United States?
Data Format: Maps, Tables, Scatter Plots, and Graph Creation
Keywords: Coal Emissions, Acid Rain, pH

Acid rain is a growing environmental issue that stems from the coal plants we rely on to produce electricity for daily activities like lighting your home or powering your cell phone. Scientists researched the relationship of emissions from coal burning, acidification of Adirondack lakes and rivers, and fish species abundance. Through charts and graphs, students will learn about the water cycle and be able to connect it to the correlation between coal plant emissions, acid rain and acidification, and decreasing number of fish species in the Adirondack region.

Ozone

Understanding the Ozone
How does ozone depletion affect Earth's atmosphere and our environment?
Data Format: Images, Scatter Plots
Keywords: Ozone, Atmosphere, Radiation

Through different activities and data analysis, students will be able to understand the importance of ozone in our atmosphere, how ozone depletion occurs and how humans play a role in its depletion. Students will also have the opportunity to discuss the effects the 1987 Montreal Protocol has had on the atmosphere.

Malaria DDT

The Relationship Between DDT and Malaria
How does a pesticide affect the number of humans diagnosed with malaria?
Data Format: Tables, Bar Graphs
Keywords: Pesticides, Malaria, Abiotic and Biotic Factors, Energy Flow

Through data analysis, students will be able to analyze the relationship between malaria, DDT and insecticide-treated netting. Students can relate this information to abiotic and biotic factors, energy flow through ecosystems, and how humans affect these ecosystems.

Zebra Mussels

Zebra Mussels: An Invasive Species
How do humans contribute to one of the fastest-growing invasive species in the Great Lakes and Hudson River ecosystems?
Data Format: Maps, Line Graphs, Images
Keywords: Invasive Species, Ecosystems, Trophic Levels

Zebra mussels are an invasive species that were brought to North America via ocean-going ships and are rapidly changing the Great Lakes and Hudson River ecosystems. Through data and graphs, students will be able to understand the effect zebra mussels have on many different species and construct food webs of ecosystems with and without zebra mussels present.

Yellowstone Falls

Yellowstone Food Webs
How does the reintroduction of wolves in Yellowstone National Park affect elk and aspen?
Data Format: Line Graphs, Images
Keywords: Predator/Prey Relationships, Trophic Levels, Ecosystem Balance

In 1992, Yellowstone National Park reintroduced wolves into the local ecosystem. This reintroduction affected the elk population as well as its food source, the aspen population. Students will use data and graphs to better understand trophic levels and the importance of key species in ecosystems.

Urban Birds
How does urban light pollution affect birds living in close proximity?
Data Format: Bar Graphs, Graph Creation
Keywords: Light Pollution, Phenology, Bird Reproduction

Birds living in cities are living in different ecosystems than their forest-dwelling counterparts. One team of researchers wanted to understand the affect of artificial light at night on bird reproduction. They compared the reproductive cycles between city and forest-dwelling blackbirds to understand when blackbirds were reproducing and for how long. Students will walk through data to understand the research question, the experimental design and the research outcome.
