Chemistry of Water: Mars Exploration—Is There Water on Mars?

During this web seminar, participating educators found out how to incorporate the Chemistry of Water: Mars Exploration—Is There Water on Mars? lesson into their physical science classes. They got an overview of the inquiry-based lesson and refreshed their understanding of how atmospheric pressure and vapor pressure affect the boiling point of water. They learned how to explain to students why water’s boiling temperature is pressure dependent, rather than temperature dependent, which allows scientists to deduce if there could be liquid water on Mars. Participants discovered how to engage students with NASA’s search for water on Mars.


This web seminar is part of a series of electronic professional development experiences sponsored by the NASA Explorer Schools (NES) project. NASA Explorer Schools invests in science, technology, engineering, and mathematics educators to inspire and engage a whole generation of future scientists, engineers and technicians that NASA needs to continue our journey. NES gives educators of grades 4-12 free access to NASA’s people, missions, research, and facilities. We take the work out of searching through thousands of materials on the NASA website and provide a comprehensive set of teaching materials for dozens of STEM concepts.
