Grades 912. Students examine microorganisms and create a food chain based on observed feeding patterns. Students explore energy transfer through different trophic levels of a food chain using a simulation activity. Using their finding that all energy is not transferred, students calculate the energy flow through the food chain they created. Carefully plan the arrival of the cultures; Didinium will die if not used within 1 day of receipt. Kit accommodates 30 students working in pairs.

Kit accommodates 30 students working in pairs and includes a prepaid coupon to request the perishable materials later at your convenience. Contact us or return the coupon at least 2 weeks prior to requested delivery date to ensure prompt arrival of material. Note: Be sure to carefully plan the arrival of your perishables; Didinium will starve to death if not used within 1 day of receiving the culture. We recommend planning to receive this culture on a Monday or Tuesday so it can be used immediately.
