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 interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.
In this activity, students model trophic cascades using cards of organisms from seven different habitats. The activity is designed to illustrate the species relationships in a food chain and the effect of predators on the trophic levels below.
This activity guides the analysis of a published scientific figure from a study on how termite mounds can enhance an ecosystem’s resilience to drought.
In this activity, students collect and analyze data from a hands-on model to discover why even slight variations in beak size can impact a bird’s ability to obtain food and survive.
This hands-on lab activity serves as an introduction to the film The Birth and Death of Genes. Students simulate and compare how blood pumps through the circulatory system of icefish and other fish.
This hands-on activity serves as an introduction to the film The Birth and Death of Genes. Students investigate the importance of antifreeze proteins for icefish survival through one of two short labs.
