A Chilling Case Study – Raining Iguanas
Engage your students with a real-world, biology-based phenomenon: Florida’s “raining iguanas.” During sudden cold snaps, iguanas lose muscle control and fall from trees, providing a dramatic example of ectothermy, torpor, and homeostasis. This case study combines observation, data interpretation, and critical thinking to help students connect behavior, physiology, and environmental influences. Students can complete this…

Modeling Ecological Pyramids
Looking for a way to include hands-on activities in an ecology unit? I’ve struggled with student engagement in this unit, mainly because so many of the concepts involve models. In this activity, students use beads to model the three types of ecological pyramids: pyramid of numbers, pyramid of biomass, and pyramid of energy. Each group…
