2026 Western Colorado Elementary Science Fair (3-5th Grade)
Calling all future scientists and engineers! EUREKA! and D51 are partnering to host our annual elementary science fair! Here’s your chance to apply your love of STEM by creating and conducting your own scientific investigation. Participation is free for all 3-5th grade students, and students can either enter as an individual or as a team of no more than 3 members. Judging will be based on grade, so there will be separate prizes for 3rd, 4th, and 5th graders. If a team is composed of students from multiple grades, that poster will be judged in the grade category of the oldest participant’s grade.
Participation is open to all 3-5th graders living in Western Colorado!

Safety Regulations
It is important to wear proper protective gear when appropriate, such as gloves, googles, and aprons, in addition to disposing of waste properly when conducting a scientific investigation. We strongly recommend that guardians look up and study Safety Data Sheets for any chemicals that their students use, and accept responsibility for not allowing students to experiment with hazardous chemicals. Safety Data Sheets can be found through OSHA’s website at osha.gov.
Projects that include the following components go against our safety regulations, and will not be displayed or judged. These include, but are not limited to:
- Poisons, drugs, or controlled substances
- Blood or other bodily fluids
- Dissection of animals that are not professionally preserved
- Hazardous devices, such as firearms, weapons, and ammunition.
- Harm towards pets or animals
- Harm towards self or others
- Consumption or injection of medication
EUREKA! holds the right to not display projects if they believe the components break our safety regulations. Please contact EUREKA! directly to discuss if you are unsure about your student’s project.
By submitting a registration form, all attending participants authorize, allow, and release the unlimited publication of any audio, video and/or photographic images without payment of compensation or royalties.
