Rockville Science Day

Rockville Science Day

Rockville Science Day is the biggest STEM festival in Montgomery County, and after 35 years they've got the formula dialed in. Over 120 exhibitors set up across Montgomery College's Rockville campus with hands-on activities that actually get kids excited about science. We're talking building and launching rockets, looking through telescopes, meeting live reptiles, exploring electric vehicles, tackling coding challenges, and running chemistry experiments. It's not a "look but don't touch" situation — kids get to build, break, mix, and launch things. About 4,000 people show up every year, but the campus is big enough that it never feels claustrophobic. Opening ceremonies at 1pm. Free parking. Free admission. Rain or shine.

Parent Tips 💡

• ✓Opening ceremonies start at 1pm, but the exhibits open at noon — arrive early to beat the rush and have first pick of activities.
• ✓The rocket-building station is the most popular — go there first. Lines get long after 2pm.
• ✓Bring your own water and snacks. Food is available for purchase but options can be limited.
• ✓Rain or shine event — check the weather and bring layers or umbrellas.
• ✓Best for ages 4 and up. Younger kids will enjoy the reptiles and vehicles but may not engage with the more technical exhibits.
• ✓The campus is spread out — wear comfortable shoes and bring a stroller for little ones.
