1. What sets Purdue's program apart? (top)

The Department of Earth, Atmospheric, and Planetary Sciences at Purdue has many wonderful things to offer to its students. The faculty-to-student ratio is very high, and all undergraduates are encouraged to take part in research. Some majors offer summer field camps and trips as part of the course of study. Purdue also has a lot of spectacular equipment available for its students, including a state-of-the-art automated electron microprobe, an atomic absorption spectrophotometer, an ion chromatograph, a gamma ray spectrometer, magnetometers, gravimeters, seismographs, a complete wet-chemical lab for analysis, and a low-level scintillation counter for age-dating ground-water recharge by tritium analysis. The program is set up to allow students a great deal of specialization in one of five majors:

  • Atmospheric Science
  • Earth/Space Science Education
  • Environmental Geosciences
  • Geology and Geophysics
  • Planetary Sciences

2. What can I do with an EAPS degree from Purdue? (top)

Atmospheric Science graduates often find work in broadcast meteorology, operational meteorology, climatology, and satellite meteorology. Planetary Sciences graduates have job choices in places such as with NASA during planning of space missions. Earth Sciences graduates might want to consider gas and oil companies locating and planning new fields. Environmental graduates are qualified to work on many contemporary environmental issues. Students in all areas can find work as scientists, doing research, as engineers, educators, environmental regulators, and with the government. In addition, graduates go directly on to graduate school for advanced study.

3. How should I prepare for the EAPS program in high school? (top)

Take as much calculus, additional math, chemistry, physics, and computer science as possible, as well as a variety of additional science courses. Continue taking your foreign language and writing courses. Those interested in meteorological broadcasting should take communications classes as well.

4. What courses will I take as an EAPS student? (top)

  • In your first two years, you will take courses covering The Dynamic Earth, Physical Geology, Science of the Atmosphere, or Planets.
  • Additional Earth, Environmental, Atmospheric, or Planetary Science courses
  • General Education electives
