2026 Division C Event Descriptions

This is a list of all events available in the 2026 Science Olympiad Rules Manual.

For Regional Tournaments, a subset of 12-14 of these events will be held at each location. Specific events for each tournament will be posted to the respective tournament page.

For the State Tournament, we attempt to hold all events.

Anatomy and Physiology

Participants will be assessed on their understanding of the anatomy and physiology for the human Integumentary, Muscular, and Skeletal systems.

Astronomy

Teams will demonstrate an understanding of Stellar Evolution: Star Formation and Exoplanets.
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.
Bungee Drop Each team will design one elastic cord to conduct two separate drops at a given height(s) and attempt to get a drop mass, placed in a bottle, as close as possible to, but without touching, a landing surface.

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 Periodicity and Equilibrium.
Circuit Lab Participants must complete tasks and answer questions about electricity and magnetism.
Codebusters Teams will cryptanalyze and decode encrypted messages using cryptanalysis techniques for historical and modern advanced ciphers.
Designer Genes Teams will answer questions, solve problems, and analyze data pertaining to classic, evolutionary, and molecular genetics.
Disease Detectives Students will use investigative skills in the scientific study of disease, injury, health and disability in populations or groups of people.
Dynamic Planet
Participants will demonstrate an understanding of the processes involving the cryosphere of the Earth including glaciers and other ice formations and processes.
Electric Vehicle Teams must 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.
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.
Entomology Students will be asked to identify insects and selected immature insects by order and family, answer questions about insects, and use or construct a dichotomous key.
Experimental Design This event will determine a participant's ability to design, conduct and report the findings of an experiment entirely on-site.
Forensics

Given a scenario and some possible suspects, students will perform a series of tests. These tests, along with other evidence or test results, will be used to solve a crime.

Helicopter Prior to the tournament teams design, construct and test free flight rubber-powered helicopters to achieve maximum time aloft.
Hovercraft Prior to the competition, participants will design, construct, and calibrate a self-propelled air-levitated vehicle that moves down a track.
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.
Materials Science Teams will complete lab activities and answer a series of questions related to the materials science of ceramics with an emphasis on chemical and crystalline structure, and behavior.
Microbe Mission Teams will answer questions, solve problems and analyze data pertaining to microbes.
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.
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.
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.
Water Quality Participants will be assessed on their understanding and evaluation of freshwater aquatic environments.
