I Can't Live Without You!: A Close-up Examination of Microorganisms Involved in Mutually Beneficial Symbiotic Relationships

In this activity, learners prepare samples for microscopic observation from a termite hindgut, a lichen, and a legume root nodule. Learners use microscopes to examine mutually beneficial symbiotic relationships that exist between microbes and other microbes, plants, and animals. Time for activity can be split between multiple meetings.
