Division C – High School at the Arkansas Science Olympiad State Tournament (2025-2026)

*NOTE: List of Arkansas events will be posted in December

  1. Anatomy and Physiology: Participants will be assessed on their understanding of the anatomy and physiology for the Nervous, Special Senses, and Endocrine Systems of the human body.
  2. Astronomy: Teams will demonstrate an understanding of Stellar Evolution From Formation to Destruction.
  3. Boomilever: Teams will design and build a cantilevered beam or truss structure that extends from a vertical Testing Wall and supports a load at a specified distance from the Testing Wall. The structure must meet the requirements specified in these rules to achieve the highest score, which is a combination of structural efficiency and Load Scored Bonus.
  4. Bungee Drop: Each team will design one elastic cord to conduct drops at a given height(s) and attempt to get a weighted bottle as close as possible to, but without touching, a landing surface.
  5. Chemistry Lab: Teams will complete one or more tasks and answer a series of questions involving the Science processes of chemistry, focused in the areas of chemical reactions/stoichiometry and kinetics.
  6. Circuit Lab: Participants must complete tasks and answer questions about electricity and magnetism.
  7. Codebusters: Teams will cryptanalyze and decode encrypted messages using cryptanalysis techniques for historical and modern advanced ciphers.
  8. Designer Genes: Teams will answer questions, solve problems, and analyze data pertaining to classic, evolutionary, and molecular genetics.
  9. Disease Detectives: Students will use investigative skills in the scientific study of disease, injury, health and disability in populations or groups of people.
  10. Dynamic Planet: Teams will complete tasks related to physical and geological oceanography.
  11. Electric Vehicle: Teams design, build, and test one vehicle that uses electrical energy as its sole means of propulsion to travel as quickly as possible and stop close to a Target Point.
  12. Engineering CAD: Teams will read a set of engineering drawings and collaborate to CAD parts in Onshape and then incorporate these parts with provided components to create an assembly.
  13. Entomology: Students will be asked to identify insects and selected immature insects by indicated taxonomy order and family, answer questions about insects, and use or construct a dichotomous key. All insects will be representatives of insects found in North America, north of Mexico.
  14. Experimental Design: This event will determine the participant’s ability to design, conduct, and report the findings of an experiment entirely on-site.
  15. Helicopter: Prior to the tournament, teams will construct, collect data on test flights, analyze and optimize a free flight rubber-powered helicopter to achieve maximum time aloft.
  16. Hovercraft: Prior to the competition, participants will design, construct, and calibrate a self-propelled air-levitated vehicle that moves down a track.
  17. Machines: Teams will complete a written test on simple and compound machine concepts and construct a lever-based measuring device prior to the tournament to determine the mass ratios between three test masses.
  18. Remote Sensing: Participants will use remote sensing imagery, data, and computational process skills to complete tasks related to climate change processes in the Earth system.
  19. Robot Tour: Teams design, build, program and test one Robotic Vehicle to navigate a track to reach a target at a set amount of time as accurately and efficiently as possible.
  20. Rocks and Minerals: Teams will identify and classify rocks and minerals and demonstrate knowledge of how rocks and minerals help to understand geologic processes, interpretation of Earth’s history, the development of natural resources, and use by society.
  21. Water Quality: Participants will be assessed on their understanding and evaluation of freshwater aquatic environments.
