Chemical Elements: GENESIS--What Are We Made Of?

During this web seminar, teachers learned how to use a hands-on activity to integrate mathematics and physical science in the classroom. They discovered how students can use statistical sampling to estimate the chemical composition of the sun. In the hands-on activity “What Are We Made Of? The Sun, Earth and You,” students analyze data in a similar way as scientists analyzed solar particles collected by the GENESIS spacecraft. Participating educators got an overview of the activity, participated in a demonstration of the lab, received background information about the nature of the elements, and watched a video about the GENESIS mission.


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.
