Division C

''For Elementary School events, see Division A. For the Middle School competition, see Division B.''

Division C Science Olympiad is for high school students, in 9th to 12th grade. Out of the fifteen students on a team, a maximum of seven members can be in 12th grade. All students on a team must be from the membership school. Team membership rules may vary by state, and many states allow multiple teams per school.

2018-2019 Short Event Descriptions:

 * Copied directly from soinc.org

Anatomy and Physiology (Cardiovascular, Lymphatic, Excretory)
Understand the anatomy of the human body systems: cardiovascular, lymphatic and excretory.

Astronomy (Stellar Evolution and Galaxies)
Teams will demonstrate an understanding of stellar evolution in normal and starburst galaxies.

Boomilever
Teams will design and build a Boomilever meeting requirements specified in the rules supporting a minimum load and to achieve the highest structural efficiency.

Chemistry Lab (Acids and Bases and Physical Properties)
Teams will complete one or more tasks and answer a series of questions involving the science processes of chemistry focused in the ares of Physical Properties and Acids and Bases.

Circuit Lab
Participants must complete tasks and answer questions about electricity and magnetism.

Codebusters
Teams will cryptanalyze (decode) encrypted messages using cryptanalysis techniques and show skill with advanced ciphers by encrypting or decrypting a message.

Designer Genes
Participants will solve problems and analyze data or diagrams using their knowledge of the basic principles of genetics, molecular genetics and biotechnology.

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 (Glaciers)
Students will use process skills to complete tasks related to glaciers, glaciation and long-term climate change.

Experimental Design
This event will determine a participant's ability to design, conduct and report the findings of an experiment conducted entirely on site.

Fermi Questions
Teams provide answers to a series of Fermi Questions, which are science-related questions that seek fast, rough estimates of a quantity which is either difficult or impossible to measure directly.

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

Fossils
Teams demonstrate their knowledge of ancient life by completing selected tasks at a series of stations including but not limited to fossil identification, answering questions about classification, habitat, ecologic relationships, behaviors, environmental adaptations and the use of fossils to date and correlate rock units.

Geologic Mapping
Teams will demonstrate understanding in the construction and use of topographic maps, geologic maps, and cross sections, and their use in forming interpretations regarding subsurface structures and geohazard risks.

Herpetology
This event will test knowledge of amphibians and reptiles.

Hovercraft
Participants will be tested on their knowledge of classic mechanics and related topics as well as their ability to construct a self-propelled air-levitated vehicle that moves down a track.

Materials Science (Polymers)
Participants will complete lab activities and answer a series of questions related to the materials science of polymers and plastics with an emphasis on chemical structure, reactivity and behavior.

Microbe Mission
Teams will answer questions, solve problems and analyze data pertaining to microbes.

Mission Possible
Prior to the competition, participants will design, build, test and document a Rube Goldberg-like device that completes a required Final Task using a sequence of consecutive energy transfers.

Mousetrap Vehicle
Teams design, build and test a vehicle using one or two snap mousetraps as its sole means of propulsion to push a paper cup forward, reverse direction, and stop as close as possible to a target point.

Protein Modeling
Students will use computer visualization and online resources to construct physical models of the CRISPR Cas9 protein that is being engineered to edit plant and animal cell genomes, and answer a series of questions about the chemistry of protein folding and the interaction of structure and function for model proteins.

Sounds of Music
Teams must construct and tune one device prior to the tournament based on a 12-tone equal tempered scale and complete a written test on the physics of sound.

Thermodynamics
Teams must construct an insulated device prior to the tournament that is designed to retain heat and complete a written test on thermodynamic concepts.

Water Quality
Participants will be assessed on their understanding and evaluation of aquatic environments.

Wright Stuff
Prior to the competition teams design, construct and test free flight rubber-powered monoplanes to achieve maximum time aloft.

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.
