National Ocean Sciences Bowl - Trout Bowl

The NOSB is an academic competition and program that engages high school students in ocean science.

National Ocean Sciences Bowl - Trout Bowl

Since 1999, CIRES Education Outreach has hosted the Trout Bowl, the only regional NOSB competition in a completely land-locked state! This quiz-show style competition engages teams of high school students from one of the largest geographic areas - including Colorado, Utah, Wyoming, Nebraska, South Dakota, New Mexico and Kansas.

Every year, in February or March, twelve schools travel to the University of Colorado Boulder to compete in the Trout Bowl, and the winning team then continues on to compete at the national competition in April (the finals competition travels to a new location every year).

The Trout Bowl is FREE for all students. Additionally all competing students receive a lunch, t-shirt and certificate of participation, while the top three placing teams receive plaques or trophies and prize bags. The prize bags are filled with donations from our generous Sponsors.

The Trout Bowl could not happen without the continual support of our volunteers, who donate their time every year to run a successful competition. We recruit 75-100 volunteers annually to perform a range of roles.

The Trout Bowl competition is one of the 25 regional competitions for the National Ocean Sciences Bowl.

Typically held in February or March, the Trout Bowl tests 12 teams of 4-5 students on their knowledge of scientific and technical disciplines through quick answer buzzer questions and more complex, critical thinking team challenge questions (TCQs). 

The winning team from each of the 25 regional competitions is provided transportation and room and board accommodation to advance to the NOSB Finals Competition held in a different location each year in April.

Check back for more details on the 2021 competition.

The Trout Bowl is the Rocky Mountain Regional of the National Ocean Sciences Bowl, an academic competition for high school students. We will need volunteers for morning, afternoon and all-day shifts. We need more volunteers in the morning round robins (8:00am – 1:00pm) than in the afternoon double eliminations (1:00pm – 6:00pm). Lunch is provided for volunteers and we also train all of our volunteers.

If you would like to volunteer, we request that you attend ONE training session. Trainings typically last 1-1.5 hours
