Rules & Regulations

The Southern Minnesota Regional Elementary Science and Engineering Fair, grades 3-6, the rules are modified and simplified. If in doubt about any aspect of the rules, check with the Regional Science and Engineering Fair Office. The changes are designed to reduce paperwork while ensuring student safety.

Before you begin your experiment you will need to make sure that you plan your experiment or research. Sometimes, you will need assistance from a qualified scientist or a review board. Make sure you plan your project accordingly.
