In February we started our Ocean Zone Installation. This display depicts each of the five ocean layers (sunlight zone, twilight zone, midnight zone, abyssal zone, and hadal zone/trenches). Students began by investigating the ways that certain species are physically and behaviorally adapted to survive in their particular zone (from sun-drenched plankton near the surface to the tube worms found in the darkest trenches below). Students were especially interested in researching the coldest, darkest, and lowest layer, the trenches or hadal zone, where some of the most primitive species on earth are found. At that level, the food chain is based on the process of chemosynthesis instead of on energy from the sun. For further discussion, please go to Stem Specialist Dr. Katherine Parisky's blogpost.
