2020 – 2021 Middle and High School Categories

NWSE reserves the right to divide or combine categories based upon the number of entrants. An effort will be made to notify students affected by category modifications, but such notification may not be possible due to time constraints. Categories may be entered by individuals or a small team (2 to 3 students.) There is no specific category for small teams. 

Special rule for small team projects
Each team should appoint a team leader; however, each member should be fully involved, familiar with all aspects of the project, and able to act as a spokesperson. The team must jointly submit one abstract and one research plan that specifically outlines each member’s responsibilities. All team member names must appear on the abstract and on each form.

The International Science and Engineering Fair continues to update their categories for use at ISEF. The Northwest Science Expo System is not matching all 21 categories, but this list may be useful for determining which category your high school project should enter under as they have more detailed descriptions.

High School

categorydescription
Animal ScienceStudy of animals and animal life, including the study of the structure, physiology, development, and classification of animals. Incudes ecology, physiology, development, animal husbandry, classification, animal behavior.
Behavioral & Social ScienceThe science or study of the thought processes and behavior of humans and other animals in their interactions with each other and the environment studied through observational and experimental methods.
BiochemistryThe study of the chemical substances and vital processes occurring in living organisms, the processes by which these substances enter into, or are formed in, cells and organisms and react with each other and the internal environment.
Cellular & Molecular BiologyThe study of the structure, formation, functions, and interactions of cells. Genetic manipulation. 
ChemistryThe science of the composition, structure, properties, and reactions of matter, especially of atomic and molecular systems.
Computer Science & RoboticsThe use of software and/or methodologies to demonstrate, analyze, simulate or compute. All science and engineering in which the use of machine intelligence is paramount to reducing the reliance on human intervention.
Energy & Environmental EngineeringAll science and engineering in which the management, refinement and/or conservation of energy is the goal.The development of processes and infrastructure for the supply of water, the disposal of waste, and the control of pollution of all kinds. Includes bioremediation and biofuels.
Engineering: Bio-engineering & MaterialsThe biological or medical application of engineering principles or engineering equipment to basic biological science problems. The development and study of novel characteristics and uses of natural and man-made materials that add to their performance.
Engineering: Electrical & MechanicalElectrical Systems in which information is conveyed via signals and waveforms for purposes of enhancing communications, control and/or sensing. All science and engineering in which there is movement. The movement can be by the apparatus or the movement can affect the apparatus. 
Environmental & Earth SciencesThe analysis of existing conditions of the environment and their effect on organisms/systems.  Includes effects of natural products on biological processes. Study of structure and behavior of the earth and its components.
MathematicsThe study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols. The deductive study of numbers, geometry, and various abstract constructs, or structures. Mathematics is very broadly divided into foundations, algebra, analysis, geometry, and applied mathematics, which includes theoretical computer science.
Medicine & Health SciencesBiomedical and public health research that aims to improve the health of individuals and the community by translating findings into diagnostic tools, medicines, procedures, policies and education.
MicrobiologyThe study of microorganisms, including bacteria, viruses, prokaryotes, and simple eukaryotes and of antibiotic substances.
Physics & AstronomyThe science of matter and energy and of interactions between the two. The study of anything in the universe beyond the Earth.
Plant SciencePlant development, physiology, evolution, ecology, photosynthesis, and growth.
