This activity explores images of tree growth in the Serengeti over time, which serve as a phenomenon for learning about and modeling species interactions in ecosystems.

This case study follows a 2020 COVID-19 outbreak on a cruise ship to highlight how control measures like lockdown impact disease spread.

In this activity, students identify the science practices and concepts in a Wild Hope episode.

In this collaborative activity, students explore major biodiversity threats and design, present, and refine solutions for preserving biodiversity.

This case study follows the 2019 measles epidemic in Samoa to highlight how vaccination impacts disease spread.

DNA is all around us — even in the air we breathe. Now scientists have found that air quality monitoring stations — which pull in air to test for pollution — also pick up lots of DNA that can reveal what plants and animals have been in the area.

This activity explores an image of a wildlife overpass crossing a major highway, which serves as a phenomenon for learning about habitat fragmentation and conservation.

Scientists who tracked humpback whales in Australia noticed that fewer whales wailed to find mates as their population grew.

In this activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti.

Scientists have uncovered new clues about a curious fossil site in Nevada, a graveyard for dozens of giant marine reptiles.

Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland.
