Middle school

Populations, ecosystems, resource availability

Last Updated Oct 12, 2020

This unit will introduce students to the ethical and environmental issues created by the shark finning industry.  Students will develop questions about the industry while looking at a photo of shark fins removed from living sharks. Throughout the unit, students will analyze pieces of evidence to answer their questions and eventually come to understand the environmental effects of shark finning.

Learning Objectives

Students will know

  • Population dynamics
  • Function of predator/prey relationship

Students will understand

  • How changes in populations lead to unbalanced ecosystems
  • Predator extinction can lead to extinction of other species lower down the food chain

Students will be able to

  • Investigate the effects of shark finning
  • Simulate population and ecosystem dynamics
  • Analyze data about the population dynamics to understand connections between predator, prey, and producers.

UNIT PLAN

Introductory Phenomenon

Students are introduced to the issue of shark finning via the image below and develop initial questions.

Questions may include:

What types of fins are those?

What types of sharks did these come from?

What are the fins used for?

How often do these sharks get killed?

How does killing sharks affect the rest of the ocean?

Activities to Gather Evidence

Shark Finning Industry

Students watch National Geographic’s Shark Fin Soup and the Smithsonian’s What if There Were No Sharks?.  They then apply their knowledge of food chain effects to a visual model.

Population Dynamics

Students use a simulation to conduct experiments and collect population data about a given ecosystem.

Real World Data

Students analyze real-world research to investigate the relationship between sharks, sea turtles, and seagrass.

Shark Conservation

Students research a shark species and design a campaign poster in favor of its conservation.

Conclusion Assessment

Students must construct a claim backed up by evidence and reasoning to answer the following question:
