As an alternative to measuring energy flow through primary productivity, students measure the transfer of energy at a higher trophic level and modify environmental conditions to explore their effects on energy consumption. In this lab, Vanessa cardui (painted lady butterfly) larvae, representing a primary consumer, feed on a growth medium that represents a primary producer. Students investigate how efficiently developing butterflies convert food into body mass. They then analyze results, calculate efficiency, and build food chains by constructing ecological pyramids. The lab requires 10 to 15 days to complete.
This kit provides materials for 30 students working in pairs and ships with perishable material included. Digital teacher’s manual, included FREE with kit purchase, is a 12-month eBook license to the Primary Consumer Energy Flow Teacher’s Manual and Student Guide.
