This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.
In this activity, students analyze scientific figures to understand principles of island biogeography theory that determine the number of species in an isolated habitat.
This activity guides the analysis of a published scientific figure from a study that explored the relationship between species number and habitat size for arthropods living on desert shrubs.
This activity guides the analysis of a published scientific figure from a study that explored the relationship between species number and habitat isolation for arthropods living on desert shrubs.
This activity guides the analysis of a published scientific figure from a study that explored habitat fragmentation and corridors in a model ecosystem.
In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.
This activity explores an image of a wildebeest herd on the Serengeti, which serves as a phenomenon for learning about population dynamics and wildlife management.
This activity guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.
This activity guides the analysis of a published scientific figure from a study that investigated the effects of tourism on cougars and cottonwood trees in a national park.
This activity analyzes a published scientific figure from a study in Serengeti National Park, Tanzania. In this study, scientists investigated how the eradication of rinderpest disease led to a boom in the wildebeest population.
This activity accompanies the video Seed Dispersal and Habitat Fragmentation. Students use data from published studies to understand patterns of seed dispersal and apply these ideas to the design of a conservation area.
