Exploring Energy Transformation in Plants

Middle School
High School
Investigation

The ability to explain the processes by which plants capture, store and use energy for growth and development is fundamental to understanding bioenergy. In this set of lessons, students investigate how plants harness and use different sources of energy during germination and growth. Students ask questions and make predictions about the sources of energy that plants use. They then plan and carry out investigations using Wisconsin Fast PlantsĀ® to collect evidence to test predictions and construct scientific arguments.
