This activity guides the analysis of a published scientific figure from a study that explored inbreeding depression in a small, isolated population of wolves.
In this inquiry-based activity, students investigate the phenomenon of fur colors in rock pocket mice to connect genotypes to phenotypes and molecular genetics to evolution.
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.
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 investigated how gene duplication contributed to the evolution of electric fish.
This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations.
This activity complements the animated short video Seeing the Invisible. Students explore concepts related to relative size and scale using cards of cells and microorganisms.
In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.
This hands-on activity allows students to analyze DNA sequences of Ebola viruses. Students use these sequences to track the virus’s spread during the 2013–2016 Ebola outbreak in West Africa.
