2025 Division B Events

Alaska Science Olympiad 2025 consisted of 16 Division B Events. Consult the Science Olympiad 2025 Division B Rules Manual for detailed event descriptions and rules.

Participants will solve problems and answer questions about agricultural sciences using their knowledge of ecology, animal and plant biology, and environmental chemistry.
Prior to the competition, teams will design, construct, and calibrate a single device capable of launching projectiles onto a target.
Participants will be assessed on their understanding of the anatomy and physiology for
the integumentary, skeletal, and muscular systems of the human body.
Teams will cryptanalyze and decode encrypted messages using cryptanalysis techniques for historical and modern advanced ciphers.
In this event, 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.
Participants will use their investigative skills in the scientific study of disease, injury, health, and disability in populations or groups of people.
Participants challenged their ability to design, conduct and report the findings of an experiment entirely on site.
Teams identify and classify fossils and demonstrate their knowledge of ancient life. Tasks will be related to interpretation of past environments and ecosystems, adaptations, evolutionary relationships, and the use of fossils in dating and correlating rock units.
Prior to the tournament, teams will construct, collect data on test flights, analyze and optimize free flight rubber-powered helicopters to achieve maximum time aloft.
Participants will use scientific process skills involving qualitative and quantitative analyses to demonstrate an understanding of the factors that influence world climate and climate change through the interpretation of climatological data, graphs, charts and images.
Teams will answer questions, solve problems, and analyze data pertaining to microbes.
Prior to the competition, participants design, build, test, and document a Rube Goldberg®-
like Device that completes required Start and Final Actions through a series of specific actions.
This event is about chemical properties and effects of specified toxic and therapeutic chemical substances, with a focus on household and environmental toxins or poisons.
Participants will demonstrate an understanding of late-stage stellar evolution and stellar remnants, and their observation across the electromagnetic spectrum.
Participants will interpret questions based on one or more state highway maps, USGS topographic maps (or portions thereof) maps, Internet-generated maps, a road atlas, or satellite/aerial images.
Teams will design and build a Tower (Structure) constructed of wood, bonded by adhesive, spanning a 20 cm square opening, able to support the loading block at least 50 cm above the test base and allow an 8 cm diameter ring gauge to pass over the top of the tower and lowered down to a point 25 cm above the test base. Bonuses can be obtained by holding 15 kg and spanning a 29 cm circle (rather than the 20 cm square). The structure must meet the requirements specified in these rules to achieve the highest score, which is a combination of structural efficiency and bonus.
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.
