Searching for an activity that allows emerging biologists to explore symbiosis up close and personal? Pupils collect samples and view lichens through a microscope and conclude with a discussion about the relationship they have with other organisms in nature. The materials also offer an alternative method for individuals who are sensitive to mold/fungus.

Instructional Ideas

• Research the concept of coevolution; for example, how the shape of flowers has evolved to fit insects required for symbiosis
• Have students create "Wanted" posters as part of their class presentation

Classroom Considerations

• Ensure noone has mold or fungus allergies; if so, use prepared slides instead

Pros

• Can be differentiated and adapted as needed
• Hands-on application allows students to see symbiotic relationship as it occurs

Cons

• None
