A signature icebreaker event for the students at the Regeneron International Science & Engineering Fair (ISEF) that is host to the traditional exchange of lapel pins that represent a student’s fair, city, country and/or culture.

Studies of the environment and its effect on organisms/systems, including investigations of biological processes such as growth and life span, as well as studies of Earth systems and their evolution.

National Geographic Society has made a two-year commitment to sponsor the earth and environmental sciences category in addition to a delegation of finalists from Washington, DC. Additionally, National Geographic will be sponsoring the Pin Exchange, a signature event at Regeneron ISEF, featuring an ice breaker activity where students trade lapel pins representing their state or country with as many students as they can meet from other places in the United States and around the world.
