The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.

However, plants experience normal growth given that directional light is provided. [10] Normal growth is classified as opposite root and shoot growth direction. This being said, many plants grown in a space flight environment have been significantly smaller than those grown on Earth's surface and grew at a slower rate. [10]

The school's computer systems lab is one of the few high school computing facilities with a supercomputer. In 1988, a team from the school won an ETA-10P supercomputer in the SuperQuest competition, a national science competition for high school students. [55] The ETA-10P was damaged by a roof leak in the 1990s.
Students returning to school are assisted by the DPI Intake Counselors, who work with recovered students to help the student re-adjust to being in school and receive an ILP.
