Symbiosis Foldable
Students will create a foldable depicting three symbiotic relationships: mutualism, commensalism, and parasitism. Students will identify examples of symbiotic relationships.

This activity includes an introduction to symbiosis, entrance tickets, exit tickets, foldable, answer keys/example, and rubrics.

The foldable can be added to an interactive notebook or used as a stand alone activity.

You will receive a PDF of the foldable and a PPT of the questions and symbiosis information so you can easily project the information on your board.
