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 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 video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.
This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.
This interactive module connects to an online citizen science platform for identifying animals in photos collected by trail cameras in Darién and Soberanía National Parks in Panama.
This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.
