The Wisconsin Science Festival (WSF), now in its 15th year, returns Oct. 16-26 with more than 600 events across 56 counties—breaking its previous record of 52 counties. What began in 2011 as a three-day, Madison-only gathering has grown into a 10-day, statewide celebration of science, technology, engineering, art and math for people of all ages, backgrounds, and interests. A centerpiece of this festival is Science in a Bag — an initiative that will deliver 3,000 drawstring backpacks, each filled with ten to twelve hands-on experiments and activities designed to spark curiosity, plus access to an online portal for more ways to engage with STEAM.
