Award Updates
Below is a list of the projects who have received a CATEGORY AWARD (1st, 2nd, 3rd, or 4th) OR a SPECIAL AWARD, listed in ALPHABETICAL ORDER (NOT in order of placement). Please scroll all the way down on the document since we had more high school projects compared to middle school.
We did our absolute best to make sure this list was fully comprehensive!
We thank you for a great science fair this year and look forward to seeing you at the Award Ceremony on March 21st!
Make plans to attend the award ceremony - Missing the Award Ceremony - students missing the ceremony can have a proxy (parent or teacher) pick up awards at the end of the ceremony on March 21, 2026. The proxy will have to sign up on a Google Form. If no proxy is cleared to pick up awards, students will forfeit all physical awards (such as monetary awards, certificates, ribbons, medals, and other materials). Students will maintain the status; including advancement to the next level fairs.
