In this interactive dive through Australia's Great Barrier Reef, discover relationships that have evolved between the resident organisms. Some are predators and prey; others compete for space, food, or mates; and still others are dependent or codependent on each other. Select one of four reef zones, then click on a type of relationship, predation and parasitism, competition or commensalism and mutualism to learn more about these relationships among reef creatures.

"…Everything affecting the gopher tortoise's habitat affects the tortoise and … eventually affects all other organisms in its ecosystem. Efforts to save the gopher tortoise are really a manifestation of our desire to preserve intact, significant pieces of the biosphere. …We must preserve…the gopher tortoise and other species in similar predicaments, for if we do not, we lose a part of our humanity, a part of our habitat, and ultimately our world." — Dr. George W. Folkerts, "The Gopher Tortoise: A Species in Decline"

The gopher tortoise of the southeastern United States is a reptile that creates and lives in a subterranean burrow primarily in dry upland habitats. The are also found among coastal dunes. More than 350 species depend upon the gopher tortoise burrow for protection from temperature extremes and periodic fires. The fires, in turn, ensure that the canopy is open for plentiful sunlight. Low growing vegetation is the tortoise's primary diet and depends on open sunny areas. The animal species living in the burrow are known as commensals and include hundreds of invertebrates and vertebrates that would not survive without the burrows these tortoises create. This lesson is designed for students to deepen their understanding about symbiotic relationships and, most importantly, learn that the removal of a keystone species (the gopher tortoise) affects the entire food web of the habitats in which these inhabitants exist.

In this Model-Eliciting Activity (MEA), students will investigate the introduction of a non-native, i.e. invasive, species to the Florida Everglades: the Burmese Python. Students will investigate the complex predator-prey relationship and learn why this could damage the ecosystem permanently. Students will analyze a set of data to determine which method of eradication would be best and most effective, considering factors such as cost, the amount of man-power necessary to implement it, the effect it would have on the python population, and its impact on other species.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator. To learn more about MEAs visit: https://www.cpalms.org/cpalms/mea.aspx
