The Lawrence Hall of Science develops interactive [[planetarium]] shows for its own planetarium and other small planetariums. The planetarium was built in 1973 and directed by Alan Friedman. The Holt Planetarium's programs have focused on audience participation, an innovation that has changed the way small planetariums around the world present astronomy to the public. In 2000 the Holt Planetarium was deemed "The Best Planetarium in the Whole World" by The Planetarian, Journal of the International Planetarium Society.<ref>{{cite journal |last1=Haskins |first1=Jane |title=The Best Planetarium in the Whole World |journal=The Planetarian |date=March 2000 |volume=29 |issue=1 |page=65 |url=https://www.planetarium-activities.org/about-pass/the-best-planetarium |access-date=16 October 2021}}</ref>

The planetarium presents live, interactive shows (approximately 25 minutes long), following the hands-on philosophy of science education. 

The Holt Planetarium has a strong interactive approach to astronomy education. Their programs actively engage audience members in activities such as finding constellations, searching for exoplanets, and so forth. The planetarium at Pacific Science Center in Seattle (originally called Star Lab, now called the Willard Smith Planetarium) was directly modeled on the Holt. Dennis Schatz was hired in 1977 from Lawrence Hall of Science as the opening director of the [[Pacific Science Center]] planetarium.
