A cake encourages students and their teachers to dream big during the NASA Explorer Schools Symposium.

A cake encourages fourth- through 12-grade students and their teachers from across the nation to "dream big" during the NASA Explorer Schools Symposium in Florida. During the event, May 4-7, about 60 students will tour NASA's Kennedy Space Center, the U.S. Astronaut Hall of Fame, and participate in several educational activities and a career panel question-and-answer session. The symposium also offers professional development opportunities for about 30 teachers.

The participants were competitively selected after they completed an original investigation focused on existing NASA missions or research interests. Photo Credit: NASA/Kim Shiflett
