In this card activity, students investigate the functions of major digestive organs.

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 activity analyzes a published scientific figure from a study that investigated the biological importance of sleep. In this study, scientists tested whether sleep plays a role in removing harmful substances from the brain.

This activity allows students to use authentic scientific data to make claims about the threat of coral bleaching for reefs around the world.

In this activity, students evaluate and discuss statements about the evolutionary relationship between milk consumption and lactose tolerance discussed in the short film Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture.

In this activity, students simulate a lactose tolerance test, similar to the one shown in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, to determine which samples contain the lactase enzyme.

This activity explores the content and research presented in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which describes a case of recent human evolution influenced by cultural factors.

This activity allows students to observe their own planarian and then design an experiment to investigate how planarians regenerate. It supports viewing of the video Identifying Key Genes in Regeneration.
