In this activity, raffia ribbon is used to create a visual representation of the differing root depths in biofuel crops and prairie plants. The wall hanging can be used to promote discussion about plants’ ability to sequester carbon and contribute to soil carbon. Extend the learning by combining this activity with The Science of Farming research story, Growing Energy data dive, Biomass Yield and Root Growth in Crops field investigations, Bioenergy Farm Game, and Fields of Fuel computer game.
