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.

In this activity, students learn about the factors that regulate the population sizes of wildebeest and buffalo in Serengeti National Park.

In this activity, students evaluate a science news article to determine whether it is a trustworthy source of information.

In this activity, students find a scientist with whom they can relate in some way and then explore and reflect upon the impact of that scientist’s work.

This activity allows students to formulate and analyze scientific questions.

In this activity, students explore using CRISPR-Cas9 to knock out butterfly genes in order to determine their function. 

In this activity, students analyze aspects of a scientific paper that investigates genes involved in the colors and patterns of butterfly wings.

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 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 video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.
