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".

The Inner Life Of The Cell

Description:  The Inner Life of the Cell shows a white blood cell flattening out and squeezing through a capillary wall. The video then zooms in to show all the biochemical processes (e.g. transcription, translation, etc.) in amazing detail. This view of the cell as a living machine can be used to introduce a unit on the cell in middle school. In high school students can explore the details of these processes or even make videos of their own.
