National Middle School Science Bowl

The National Middle School Science Bowl is a middle school academic competition, similar to Quiz Bowl, held in the United States. Two teams of four students each compete to answer various science-related questions. In order to determine which student has the right to answer the question, a buzzer system (or "lockout system") is used, similar to those seen on popular television game shows such as Jeopardy!. The National Middle School Science Bowl (" NMSSB") has been organized and sponsored by the United States Department of Energy since the competition's inception in 2002.

Questions are asked in the categories of Physical Science, Life Science, Earth and Space Science, Energy, and Mathematics. Although they are not subcategorized, the questions fall into the subcategories of Chemistry, Algebra, Computer Science, Biology, Physics, Astronomy, Geometry, and Current Events. The newest addition was a category specially made for the 2006 National competition: a group of about 5 questions asked through graphics and models projected onto computer screens and as hard copies distributed to competing teams. These were only used in semi-finals and championship rounds.

Before the 2010 year, there was no Energy category, and Earth and Space Science was called Earth Science. The General Science category was dropped in 2017.
