2023 Division B Event Descriptions

This is a list of all events available in the 2023 Science Olympiad Rules Manual.

For Regional Tournaments, we expect to hold 12-15 of these events at each location. Specific events for each tournament will be posted to the tournament page.

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

Anatomy and Physiology
(Respiratory, Digestive, and Immune)

Participants will be assessed on their understanding of the anatomy and physiology for the human Respiratory, Digestive, and Immune systems.
Bio Process Lab This event is a lab-oriented competition involving the fundamental science processes of a middle school life science/biology lab program.
Bridge Teams will design and build a Bridge (Structure) meeting requirement specified in these rules to achieve the highest structural efficiency.
Can't Judge a Powder Students will test and characterize one pure substance and then, based only on data they collect, answer a series of questions about that substance. Students will not be asked to identify the substance. Emphasis of this event is on the quality of data collected, answering questions about the substance and providing data to support their answers.
Codebusters Teams will cryptanalyze and decode encrypted messages using cryptanalysis techniques for historical and modern advanced ciphers.
Crave the Wave

In this event competitors must demonstrate knowledge and process skills needed to solve problems and answer questions regarding all types of waves and wave motion.

Crime Busters Given a scenario, a collection of evidence, and possible suspects, students will perform a series of tests that along with other evidence will be used to solve a crime.
Disease Detectives Participants will use investigative skills in the scientific study of disease, injury, health and disability in populations or groups of people.
Dynamic Planet In this event, students will use process skills to complete tasks related to Earth's fresh waters.
Experimental Design This event will determine a participant's ability to design, conduct and report the findings of an experiment entirely on-site.
Fast Facts Teams will fill in a grid of terms that begin with a given letter to match given science categories.
Flight Prior to the tournament, teams will design, construct and test free flight rubber-powered aircraft to achieve maximum time aloft.
Foresty Participants will be assessed on their knowledge of trees found in the United States that are on the Official Science Olympiad National Tree List.
Green Generation

Students will demonstrate an understanding of general ecological principles, the history and consequences of human impact on our environment, solutions to reversing trends and sustainability concepts.

(Everyday weather)

Participants will use scientific process skills as well as qualitative and quantitative analyses to demonstrate an understanding of the factors that influence Everyday Weather.

Road Scholar Participants will answer interpretive questions that may use one or more state highway maps, USGS topographic maps, Internet-generated maps, a road atlas or satellite/aerial images.
Rocks and Minerals Teams will demonstrate their knowledge of rocks and minerals.
Roller Coaster

Prior to the competition, teams design, build, and test a Roller Coaster track to guide a ball/sphere that uses gravitational potential energy as its sole means of propulsion to travel as close as possible to a Target Time.

Solar System
(Habitability within and beyond the Solar System)

Participants will demonstrate an understanding and knowledge of habitability within and beyond the Solar System.
Sounds of Music Teams must construct and tune one device prior to the tournament based on a one-octave 12-tone equal tempered scale and complete a written test on the physics of sound and music concepts.
Storm the Castle

Prior to the competition, teams will design, construct and calibrate a single device capable of launching projectiles onto a target and collect data regarding device parameters and performance.

Wheeled Vehicle

Teams must design, build, and test one Vehicle that uses a non-metallic, elastic material as its sole means of propulsion to travel a distance as quickly and accurately as possible.

Write It Do It One student will write a description of an object and how to build it, and then the other student will attempt to construct the object from this description.
