ExploraVision is a competition for all students in grades K-12 attending a school in the U.S., Canada, U.S. Territory or a Department of Defense school. Homeschooled students are eligible to enter. It is designed to encourage students to combine their imagination with their knowledge of science and technology to explore visions of the future. Teams of students select a technology, research how it works and why it was invented, and then project how that technology may change in the future. They must then identify what breakthroughs are required for their vision to become a reality and describe the positive and negative consequences of their technology on society. Winning ideas have focused on things as simple as ballpoint pens and as complex as satellite communications. The student teams write a paper and draw a series of Web page graphics to describe their idea. Regional winners make a Web site and a prototype of their future vision.
