This activity guides the analysis of a published scientific figure from a study that modeled the impact of an infectious fungal disease on a bat population.

Developing an Explanation for Tuskless Elephants

This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.

Using Images as Phenomena

This hands-on activity engages students in asking questions about phenomena using collections of images.

Vertebrate Declines and the Sixth Mass Extinction

This activity guides the analysis of a published scientific figure from a study that measured species population declines on a global scale. These declines may be a part of Earth’s next mass extinction.

What van Leeuwenhoek Saw
