Description
Grades 9-12.
- Observe examples of predation, competition, symbiosis, and parasitism
- Practice microscope techniques to observe interactions between microscopic organisms
- Determine whether the relationships between organisms are beneficial, harmful, or have no noticeable effect to the organisms involved
Working in groups that rotate to 4 different lab stations, students observe examples of competition, predation, parasitism, and symbiosis. First, students explore predation as they observe Stentor protozoa prey upon Chilomonas. Next, students observe Amoeba and Stentor as they compete for the Chilomonas food source. Students then extract the gut contents of termites and examine protozoan symbionts. At the last lab station, students study the parasitic relationship between WOWBugs and Sarcophaga larvae.
Kit accommodates a class of up to 32 students working in pairs and includes a voucher to request the perishable materials later at your convenience.
