Participants will be assessed on their understanding of anatomy and physiology of the human RESPIRATORY, DIGESTIVE, and IMMUNE systems.

A lab-oriented competition involving the fundamental science processes of a middle school life-science/biology lab program.

Teams will design and build a Bridge (Structure) meeting requirements specified to achieve the highest structural efficiency.

Students will test and characterize one pure substance and then, based only on the data they collect, answer a series of questions about that substance. Students will not be asked to identify the substance. The emphasis of this event is on the quality of data collected, answering questions about the substance, and providing data to support their answers.

Teams will cryptanalyze and decode encrypted messages using cryptanalysis techniques
for historical and modern advanced ciphers.

Students demonstrate knowledge and process skills needed to solve
problems and answer questions regarding all types of waves and wave motion.

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

Use investigative skills in the scientific study of disease, injury,
health, and disability in populations or groups of people.

Students will use process skills to complete tasks related to Earth’s fresh waters.

This event will determine the participant’s ability to design, conduct, and report the findings of an experiment entirely on-site.

Teams will fill in a grid of terms that begin with a given letter to match given science categories

Prior to the tournament, teams will design, construct and test free flight rubber-powered aircraft to achieve maximum time aloft.

Participants will be assessed on their knowledge of
trees found in the
The United States that
are on the 2023 Official Science Olympiad National Tree List
.

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.

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

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.

Participants will demonstrate their knowledge of rocks and minerals.

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.

Participants will demonstrate an understanding and knowledge of
habitability within
and beyond the Solar System.

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

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

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

One participant will write a description of an object and how to build it. The other
participant will attempt to construct the object from this description.
