The Science Mill is a nonprofit hands-on science museum in Johnson City whose exhibits target roughly 5th-8th grade. Its summer offerings are SCI Camps (STEM Career Immersion Camps), week-long programs that pair experiences drawn from a range of STEM careers with traditional camp activities, and a Science Outside camp with a primary group for rising 4th-6th graders and a secondary group for 6th-8th graders. The museum also runs Labs on the Go outreach and homeschool days during the year.

★★★★★Gavin MedelAn old mill turned science museum out in the Hill Country! So many interesting and interactive exhibits; staff were so helpful and friendly as well - if you have kids, they'll absolutely love it here 😊
★★★★★Rexy HassellWe went there Sunday, 12/28/25. Our family had a good time. It was very educational and fun. We spent 2 hours there (2pm to 4pm) and we felt that it wasn't enough time to experience it all. We will be back to view and experience the rest of the exhibits.
★★★★★Sandra Luna-ChavezLove this place! Amazing learning environment! Food is delicious, gift shop has a lot of options!
★★★★★Michael O'NeillWhat an awesome experience! I have good friends (literally family to me) visiting my wife and I. I had additional time with my friend's two sons, so I looked up science museums, (what kid doesn't like a science museum) and I saw Science Mill as a choice. Great choice I made. Both of the boys really enjoyed Science Mill. So many interactive galleries to check out, a virtual reality that is free, movie theater, outside and inside areas to explore. Science Mill in Johnson City, TX is a wonderful, fun place to check out. Especially if you have children with you. Definitely recommend.
★★★★★Dwight AlbersI have to say I was impressed well above my expectations. This is such a gem for a small Hill Country town. I think this rivals if not surpasses some of the 'big city' museums and similar venues. The number, variety, and sophistication of the displays were interesting even for adults. While it is 'geared' for kids, as adults we found it fascinating. We spent about 3 1/2 hours here, and if it weren't for a bit of a limited attention span of elementary grandkids, we could have easily spent longer. Indoor and outdoor activities. The outdoor ball machine was great fun and we had to peel them away. The VR flying 'ride' was 2 minutes long and included with the admission. All in all, a great experience! Highly recommended.
