    The 2026 Prosser Science Expo celebrates many branches of science—from agriculture and ecology to chemistry, observation, creativity, and experimentation.

    This year we have experts on lamprey, molecular structures, fossils, a planetarium and astrocartography, soils, bugs, electricity, fire science, art, interactive experiments – and of course our favorite giant salmon Finn!  Science activities are all free and great for scientists of all ages! Food trucks and facepainting will also be on-site and available for purchase. Time: 10 am to 1 pm
