Forestry (B/C) - This event will test student knowledge of North American trees that are on the Official National Tree List.

Gravity Vehicle (C) - Teams design, build and test one vehicle and ramp that uses gravitational potential energy as the vehicle's sole means of propulsion to reach a Target Point as quickly, as accurately and as close to their predicted time as possible.

Helicopters (C) - Students will construct and test free flight rubber-powered helicopters prior to the tournament to achieve maximum flight times.

Keep the Heat (B) - Teams must construct an insulated device prior to the tournament that is designed to retain heat. Students must also complete a written test on thermodynamic concepts.

Meteorology (B) - This event involves the use of process skills as applied to meteorology (Climate).

Microbe Mission (B/C) - Teams will answer questions, solve problems and analyze data pertaining to microbes.

Mission Possible (B)- Prior to the competition, participants will design, build, test and document a "Rube Goldberg-like device" that completes a required Final Task using a sequence of consecutive tasks.

Mousetrap Vehicle (B) - Teams will design, build and test a vehicle using one mousetrap as the sole means of propulsion to reach a target as quickly, accurately and close to their predicted time as possible.

Optics (B/C) - Teams compete in activities and answer questions related to geometric and physical optics.

Protein Modeling (C) - Students will use computer visualization and online resources to guide them in constructing physical models of proteins and in understanding how the structure of the protein determines the function. For 2012, students will model proteins involved in the regulation of apoptosis as they explore the discovery and treatment of a rare (one in a billion) genetic trait discovered through genome sequencing.

Reach for the Stars (B) - Students will demonstrate an understanding and basic knowledge of the properties and evolution of stars, open clusters and globular clusters, and normal and star-forming galaxies.

Remote Sensing (C) - Teams use remote sensing imagery, science and math process skills to complete tasks related to an understanding of Earth's Hydrosphere.
