LIFE, PERSONAL & SOCIAL SCIENCE
Disease Detectives
Students will use investigative skills in the scientific study of disease, injury, health and disability in populations or groups of people.
Microbe
Mission
Teams will answer questions, solve problems and analyze data pertaining to microbes.
Remote Sensing
---
Entomology
Students will be asked to identify insects and selected immature insects by order and family, answer questions about insects, and use or construct a dichotomous key.
Ecology
Students will answer questions involving content knowledge and process skills in the area of ecology and adaptations in featured North American biomes.
EARTH & SPACE SCIENCE
Astronomy
Teams will demonstrate an understanding of Stellar Evolution: Star Formation & Exoplanets.
Dynamic
Planet
Participants will demonstrate an understanding of the processes involving the cryosphere of the Earth including glaciers and other ice formations and processes.
Fossils
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.
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 past depositional environments on Earth and other planetary bodies.
PHYSICAL SCIENCE & CHEMISTRY
Air
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.
Chem
Lab
Teams will complete one or more tasks and answer a series of questions involving the science processes of chemistry focused in the areas of Periodicity and Equilibrium.
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.
Materials Science
Teams will complete lab activities and answer a series of questions related to the materials science of ceramics with an emphasis on chemical and crystalline structure, and behavior.
Optics
Teams must participate in an activity involving positioning mirrors to direct a laser beam towards a target and are tested on their knowledge of geometric and physical optics.
Wind
Power
Teams construct a blade assembly device prior to the tournament that is designed to capture wind power and complete a written test on the principles of alternative energy.
TECHNOLOGY & ENGINEERING
Electric Vehicle
Teams must design, build and test one vehicle that uses electrical energy as its sole means of propulsion to travel as quickly as possible and stop close to a Target Point.
Helicopter
Teams will construct, collect data on test flights, analyze and optimize a free flight rubber-powered helicopter to achieve maximum time aloft.
Wifi
Lab
Teams must construct an antenna device prior to the tournament that is designed to transmit/receive a signal at 2.4 GHz and complete a written test on the principles of electromagnetic wave propagation.
Robot
Tour
Teams design, build, program and test one Robotic Vehicle to navigate a track to reach a target at a set amount of time as accurately and efficiently as possible.
Tower
Teams will design and build a Tower (Structure) meeting requirements specified in these rules to achieve the highest structural efficiency.
INQUIRY & NATURE OF SCIENCE
Bungee Drop
Team will design one elastic cord to conduct two separate drops at a given height(s) and attempt to get a drop mass, placed in a bottle, as close as possible to, but without touching, a landing surface.
Codebusters
Teams will cryptanalyze and decode encrypted messages using cryptanalysis techniques for historical and modern advanced ciphers.
Experimental
Design
This event will determine a participant's ability to design, conduct and report the findings of an experiment entirely on-site.
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.
TRIAL EVENTS
Aerial
Scramble
At the Tournament, teams will assemble, test, and fly up to two aircraft built on-site without using adhesives from unopened standardized model airplane kits.
Agricultural
Science
Participants will solve problems and answer questions about agricultural sciences using their knowledge of ecology, animal and plant biology, and environmental chemistry.
Botany
Participants will demonstrate their knowledge of plant life and general botany principles.
Cybersecurity
Competitors will be assessed on their knowledge of cybersecurity through hands-on tasks as well as theoretical questions focused in the areas of cryptography and web architecture.
Digital
Structures
Teams will design and test a Tower using SkyCiv structural analysis software that meets requirements specified in these rules to achieve the highest structural efficiency while withstanding multiple vertical and lateral loads.
Engineering
CAD
Teams will read a set of engineering drawings and collaboratively create CAD parts and assemblies that match the drawings while incorporating provided components and be able to answer questions about the drawing and generated model.
Home
Horticulture
Participants will use their investigative skills in the scientific study of home horticulture.
Mission
Possible
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.
