Concept Cartoons

Cell Division and Genetics

Diffusion and Osmosis

Metabolism, Energy and Matter

Natural Selection

Concept cartoons are single-panel images showing several characters explaining a situation.  One of the characters provides a scientifically accurate answer, and the others make statements that are incorrect, but often typically include common student ideas.  The first science concept cartoons were created by Stuart Naylor and Brenda Keogh in the late 1990’s for use in teaching physics.  Kathleen Fisher and Dianne Anderson created biology concept cartoons related to natural selection in 2002.  Since then, the collection has grown, and in 2014, artwork was redone and brand new cartoons on various biology topics were added. 

Teachers can use concept cartoons to probe the ideas held by students, and then can adjust instruction to help to move students to scientific understanding.  Concept cartoons are used by teachers as warm-up activities, as starters for small group discussions, or even as homework to do with family members.  One particularly effective in-class method is to provide each individual student with a copy of the cartoon, and ask them to indicate the answer they feel is the best, as well as to explain (in writing) why the other answers are not.  Then the small group comes to a consensus and students make a note if they change their answer, and finally the whole class discusses the cartoon and comes to a decision as to the best answer. 

This cartoon collection, as well as the explanations for the cartoons, is continually shaped and improved by user feedback!  Please send your comments to Dr. Dianne Anderson at
