This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
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.
This activity explores images of chalk formations and coccolithophores, which serve as phenomena for learning about the interactions between biological and geological processes.
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.
