The investigation involves students determining where plants store potential energy (a.k.a., chemical energy). In the investigation, students will grow rapid cycling Brassica rapa plants and observe that the dry weight (mass) increases because of photosynthesis. They will measure the amount of energy stored in seeds and vegetative tissues by using a simple calorimeter. The information collected...
The Kids Into Discovering Science (KiDS) curriculum, designed for 5th grade students, includes 10 classroom lesson plans and one field trip lesson plan centered on a plant science experiment. Over 10 lessons and a field day, students practice observation, set up and monitor an experiment, analyze and present their data, and learn about plant ecology, soil ecology, habitats, and their local...

When selecting alternative fuels, it is important to consider the relative advantages and disadvantages of each. This activity asks students to begin to consider the life cycle energy and carbon dioxide emission costs of gasoline, corn ethanol, and cellulosic ethanol. The various pieces help students trace energy and matter through a complex system and begin to critically analyze graphical...
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...
