Corn Cob Sprouting in Water

Description:  This dramatic time lapse shows corn kernels sprouting over time. Each of the kernels represents a new corn plant and so corn cobs represent a wonderful organism for studying genetics. In elementary this phenomenon can be used to show what plants need to survive. In secondary students can investigate specific crosses, analyze patterns in the offspring, and could even study transposons "jumping genes".
