The 11th Annual Harmony Science and Engineering Fair will take place Friday, April 3, and Saturday, April 4, 2026, in Houston, bringing together the brightest middle and high school students from across the Harmony Public Schools network to showcase advanced research projects. Registration opens soon with a Feb. 27 deadline, and space is limited as projects must pass an online pre-elimination process that maintains the fair's rigorous standards. H-SEF represents more than competition — it's a launching pad for future innovators that has previously sent winners to prestigious international competitions, including a first-place finish at Mostratec 2021.
