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

In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

This interactive module introduces the anatomy of the immune system and walks through the timeline of a typical immune response.

This activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This activity explores images of plant cells and structures, which serve as phenomena for learning about how plants respond to stimuli.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

The added information provided at pause points within the animation How We Get Our Skin Color allows for a richer exploration of the topic of human skin structure and function.

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.
