Students research and discover human and environmental drivers of mass extinction and develop an understanding of trophic cascades and how the loss of one species has an effect on other species and biomes. Then, in teams, they select an endangered species on which to focus their conservation efforts and identify factors influencing the species' endangerment, considering steps necessary to prevent extinction.

 

Students look at ways eco-artists actively advocate for the Earth and its inhabitants and apply the strategies to their own work as planetary stewards. Teams create a three-panel conservation pamphlet that showcases their endangered animal, including infographics or images providing further information,  three to four concrete steps people can take to help save this animal from extinction, and information about organizations dedicated to species survival. Finally, student teams look for ways to spread the message beyond their classroom, such as carrying out their conservation action plans within their own community, educating and engaging with other local actors, dividing responsibilities, and urging action on behalf of a vulnerable regional species with the help of knowledgeable and influential sponsors such as zoos, aquariums, and nonprofits.

Unit Driving Question: How can we, as planetary stewards, take an active role in saving species from extinction?

 

2 hrs 55 mins
Two scientific theories prevail as to what caused the extinction of the dinosaurs. One, an asteroid hit Earth stirring up a cloud of dust large enough to change the climate, and two, a massive volcanic eruption spewed enough carbon dioxide to alter the climate.

Students collaboratively investigate our planet’s five mass extinctions and the possibility of a sixth mass extinction. Then, students explore the Anthropocene Epoch’s cultural and environmental complexities and impacts before selecting a biome and endangered species that exist within it to be the focus of their research throughout the rest of the unit. They predict how human activity has impacted these biomes and species. This lesson is part of the Engaging in the Fight Against Extinction unit.

<p>Plastic trash in the environment drastically impacts wildlife, such as this bird photographed at the Caleta Portales beach in Valparaiso, Chile.</p>

Students explore drivers of extinction across Earth’s major biomes, including human-to environment interactions that threaten biodiversity, and seek solutions to mitigate habitat loss and prevent extinction. As a result, they develop research-based action steps critical to protecting a certain species and incorporate key findings into their culminating conservation pamphlets. This lesson is part of the Engaging in the Fight Against Extinction unit.

<p>A pair conservation workers gives orphaned orangutans a ride in a wheelbarrows at Borneo&#39;s International Animal Rescue.</p>

Students explore the varying roles people can play to save endangered species. Students create an eco-artist social media profile sharing information about artists who encourage conservation through their work. This lesson is part of the Engaging in the Fight Against Extinction unit.

Anthropocene
Noun

period of time during which human activities have impacted the environment enough to constitute a distinct geological change.

apex predator
Noun

species at the top of the food chain, with no predators of its own. Also called an alpha predator or top predator.

aquatic
Adjective

having to do with water.

Noun

all the different kinds of living organisms within a given area.

Noun

area of the planet which can be classified according to the plant and animal life in it.

bottom-up trophic cascade
Noun

ecological phenomenon in which a producer or primary consumer is removed from the environment.

chain reaction
Noun

series of events where the previous event causes the next event.

citizen
Noun

member of a country, state, or town who shares responsibilities for the area and benefits from being a member.

climate
Noun

all weather conditions for a given location over a period of time.

Noun

management of a natural resource to prevent exploitation, destruction, or neglect.

conservation ecology
Noun

study of Earth's biodiversity, with the goal of protecting species, habitats, and ecosystems. Also called conservation biology.

Noun

organism on the food chain that depends on autotrophs (producers) or other consumers for food, nutrition, and energy.

decomposer
Noun

organism that breaks down dead organic material; also sometimes referred to as detritivores

Noun

area of land that receives no more than 25 centimeters (10 inches) of precipitation a year.

Noun

any natural or human-induced factor that directly or indirectly sets a change to an ecosystem in motion.

Noun

branch of biology that studies the relationship between living organisms and their environment.

Noun

community and interactions of living and nonliving things in an area.

Noun

organism threatened with extinction.

epoch
Noun

particular period of time in history marked by an event that begins a new period.

extinct
Adjective

no longer existing.
