2023 Division C Event Descriptions

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

For Regional Tournaments, will hold 12 of these events 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 (Respiratory, Digestive, and Immune)	Participants will be assessed on their understanding of the anatomy and physiology for the human Respiratory, Digestive, and Immune systems.
Astronomy (Stellar Evolution and Variability)	Teams will demonstrate an understanding of Stellar Evolution and Variability.
Bridge	Teams will design and build a Bridge (Structure) meeting requirement specified in these rules to achieve the highest structural efficiency.
Cell Biology	This event integrates content knowledge and process skills in the areas of cell biology and cellular biochemistry.
Chem Lab (Oxidation/Reduction and Periodicity)	Teams will complete one or more tasks and answer a series of questions involving the science processes of chemistry focused in the areas of Oxidation/Reduction and Periodicity.
Codebusters	Teams will cryptanalyze and decode encrypted messages using cryptanalysis techniques for historical and modern advanced ciphers.
Detector Building	Teams will build a durable Mass/Force Sensing Device that will accurately measure and display both voltage and actual masses of different solid samples ranging from 20 to 1,000 grams.
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	Students will use process skills to complete tasks related to Earth's fresh waters.
Environmental Chemistry	This event will focus on fresh water (e.g., residential, industrial or natural), the identified pages of The Clean Water Act (1972 and 1977), wastewater operator's certification manual (Indiana March 2018 revision) and its applications, various testing of particular analytes using standardized curves (either interpreted or created), and stabilization ponds, and introduction to the National Pretreatment Program.
Experimental Design	This event will determine a participant's ability to design, conduct and report the findings of an experiment entirely on-site.
Fermi Questions	Teams provide answers to a series of "Fermi Questions"; science related questions that seek fast, rough estimates of a quantity, which is either difficult or impossible to measure directly.
Flight	Prior to the tournament, teams will design, construct and test free flight rubber-powered aircraft to achieve maximum time aloft.
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.
Forestry	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.
It's About Time	Teams will answer questions related to time and they may construct and bring one non-electrical device that triggers a single signal to occur three times at equally spaced time intervals.
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.
Rocks and Minerals	Teams will demonstrate their knowledge of rocks and minerals.
Scrambler	Teams design, build, and test a mechanical device, which uses the energy from a falling mass to transport an egg along a straight track as quickly as possible and stop as close to the center of a Terminal Barrier (TB) without breaking the egg.
Trajectory	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.
WiFi Lab	Teams must construct an antenna device prior to the tournament that is designed to transmit a signal at 2.4GHz and complete a written test on the principles of electromagnetic wave propagation.
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 the description.
