Students can enter work in any of the following categories for participation and can self select based on interest and ability.

New this year! -- There are general requirements for all entries that can be reviewed below, or downloaded as a PDF here

All Category Descriptions and Recommendations can be downloaded as a single PDF document here

Select the specific category or informational section below for further information.

Please note: The Category Descriptions have been updated for STEM Expo 5, however we are still revising the Rubrics. Please be patient - these should be updated soon.

Rube Goldberg Rube Goldberg Category Icon

The Rube Goldberg Category is intended to provide a means of discovery of physics and engineering concepts and methods.

The category description covers the device construction, the use of simple machines, and the written sequence requirements

Invention Invention icon for STEM Expo

The Invention Category is intended to provide a general area for an innovative solution to a problem, or a new single item invention.

The category description covers the illustrative design detail, the understanding of the invention's use and benefits, and design prototype construction.

Science Fiction Science Fiction icon for STEM Expo

The Science Fiction category is intended to provide a means of sharing fictional science. Good science fiction defines or declares alternative physical rules or thought processes for the environment, and then is consistent to those rules throughout the story.

Additionally, good science fiction has a good story!

The category includes not only written Science Fiction stories, but videos, plays, radio shows, graphic novels, etc.

Environmental or Agricultural Innovation Environmental Innovation icon for STEM Expo

The Environmental/Agricultural Innovation category is intended to provide a means of sharing environmentally and/or agriculturally innovative ideas.

These ideas may be new products, procedures, inventions, promotional projects, community events, etc.

Reverse Engineering Reverse Engineering icon for STEM Expo

The Reverse Engineering Category is intended to provide a means of discovery of engineering concepts and methods

The participant must take something apart and learn how it works, then explain it!

Robotics & Computer Science Robotics icon for STEM Expo

A robot is a mechanical agent that can perform tasks automatically. Similarly computer science is the design of software that can perform tasks. Computer software and robots can both be operated automatically, semi-autonomous, or remotely controlled. Both are designed to be used for one or more specific purposes.

Robotics and Computer Science development teach practical engineering, technology, and math concepts.

Scientific Inquiry Scientific Inquiry icon for STEM Expo

Scientific Inquiry is the basic experimentation category.

The items pertaining to this category cover Scientific Methodology, Research, Hypothesis, Experiment Design, Data Collection and Analysis.
