Help us fund the 2026 Fair!

We are the Eastern Iowa Science and Engineering Fair (EISEF).

Our mission is to inspire Eastern Iowa’s students to pursue careers in science, engineering, and math.

To accomplish our mission, every year we do the following:

• We challenge the students in grades 6–12 to do science projects.

• We support their parents and teachers in guiding their projects.

• We invite them to Cedar Rapids to exhibit their projects and explain what they learned.

• We recognize the deserving students with awards, prizes, and scholarships.

• We send the very best students to the International Science and Engineering Fair, to exhibit their projects alongside the best students from around the world.

• We raise funds and mobilize volunteers and resources to make all this happen.

• We try to have fun doing it, and make it fun for everyone else!

The Eastern Iowa Science and Engineering Fair (EISEF) takes place each year in March, usually on the third Saturday, in Lindale Mall in Cedar Rapids, Iowa. The next Fair is scheduled for Saturday, March 21, 2026.

EISEF is an all-volunteer run organization that depends on the generosity of individual, foundation, and corporate donors to give our students the best experience possible.

ISEF: Important Updates for 2026

Educator Guide to the International Rules, AI Use Table, and Field Work Safety Plan

In the reorganization of the 2026 International Rules, “guidance” was removed and focus was put on presenting the rules in a standard format to make them more accessible and understandable.  The Society has created a new Educator Guide which provides additional context and explanation of each section of the International Rules with additional resources and further explanation. The Educator Guide is available at this link: https://sspcdn.blob.core.windows.net/files/Documents/SEP/ISEF/2026/Rules/Rules-Educator-Guide.pdf

Society for Science and the Regeneron ISEF Scientific Review Committee have also created a Generative AI Use Table with our guidance on when it is acceptable to use generative AI in the development and execution of a research project and how to properly cite this usage. The table is adapted from an AHA Ad Hoc Committee on AI in History Education. This is a preliminary model and Affiliated fairs may adopt their own, more strict, policies. For now, we are making this table available publicly, and hope that students use it as a resource. In future years, declaration of the use of AI in certain parts of a research project presented at Regeneron ISEF may be required. The AI Use Table is available here: https://sspcdn.blob.core.windows.net/files/Documents/SEP/ISEF/2026/Rules/Generative-AI-Use-Table.pdf , as well as, in the Educator Guide.

Lastly, the Society has published a Field Work Safety Plan. This guide is meant to help students and teachers in developing a safe, environmentally responsible project and should be reviewed along with the research plan prior to experimentation. This guide is based on EPA requirements for scientists collecting air, water, and/or soil samples while working in the field. You can find the Field Work Safety Plan here: https://sspcdn.blob.core.windows.net/files/Documents/SEP/ISEF/2026/Rules/Field-Safety-Work-Plan.pdf

We encourage you to share these guides with your educators and network to be used as references and resources. All can be found on our Rules page here: https://www.societyforscience.org/isef/international-rules/. Please do not hesitate to contact us at SRC@societyforscience.org if you or your students have questions.
