Now You See Me, Now You Don't

Bioluminescence fascinates most upper elementary scientists. Display images of different glowing deep-sea organisms and discuss their environment. Young biologists then experiment with images and different colors of filtered light. In this way they contemplate how animal vision systems can differ. To conclude, they write an essay about the limits of human vision. If you could find a video about bioluminescent organisms, it would be even more vivid a presentation than just displaying photos.
