Chemists study atomic and molecular structures and their interactions. 

Students learn how to estimate the "energy efficiency" of photosynthesis, or the amount of energy that plants absorb for any given location on Earth. This is the ratio of the amount of energy stored to the amount of light energy absorbed and is used to evaluate and model photosynthesis efficiency.

Students examine satellite images of a recently formed island to identify areas of erosion and deposition.
