Biological Sciences Division
Category Name Description

Behavioral and Social Sciences

The science or study of the thought processes and behavior of humans and other animals in their interactions with the environment studied through observational and experimental methods.

Biochemistry

 

The study of the chemical substances and vital processes occurring in living organisms, the processes by which these substances enter into, or are formed in, the organisms and react with each other and the environment.

Botany

Study of plant life. Ecology, agronomy, horticulture, forestry, plant taxonomy, physiology, pathology, plant genetics, hydroponics, algae, etc.

Medicine and Health Sciences

The science of diagnosing, treating, or preventing disease and other damage to the body or mind.

Microbiology
The study of micro-organisms, including bacteria, viruses, prokaryotes, and simple eukaryotes and of antibiotic substances.

Zoology

Study of animals and animal life, including the study of the structure, physiology, development, and classification of animals. Animal ecology, physiology, animal husbandry, cytology, histology, entomology, ichthyology, ornithology, herpetology, etc.
Categories
Student entries are grouped by the field of science within which the project was performed. There are a total of 13 fields, or categories. These 13 are further grouped into "Biological" and "Physical" science divisions. Each of these 13 categories are described at the right. These categories are based on those used by the Intel ISEF as published by the Society for Science.
 
 
 
Special Note Concerning "Team" Projects: In previous years a "Team Projects" category was available for projects performed by a team of students. This special category is no longer used at the Intel ISEF and, as a result, at the Dr. Nelson Ying Orange County Science Exposition. Starting this year projects performed by a team of students are to be submitted under the scientific category of their research. For additional details and requirements please see Page 4 of the "International Rules for Pre-college Science Research: Guidelines for Science and Engineering Fairs 2010-2011".
Physical Sciences Division
Category Name Description

Chemistry

The science of the composition, structure, properties, and reactions of matter, especially of atomic and molecular systems.

Computer Sciences

The study of information processes, the structures and procedures that represent processes, and their implementation in information processing systems. It includes systems analysis and design, application and system software design, programming, and datacenter operations.

Earth and Space Sciences

The study of sciences related to the planet Earth (Geology, mineralogy, physiography, oceanography, meteorology, climatology, speleology, seismology, geography, atmospheric sciences, etc.)

Engineering

The application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of efficient and economical machines and systems.

Environmental Sciences

The analysis of existing conditions of the environment.

Mathematics

The 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.

Physics

Physics is the science of matter and energy and of interactions between the two. Astronomy is the study of anything in the universe beyond the Earth.
