The Lawrence Hall of Science
The public science center of the University of California, Berkeley.
Open Wednesday - Sunday
10:00 a.m.–5:00 p.m.
On a visit to The Lawrence, students collaborate to investigate new ideas as they become scientists and engineers for a day.
We partner with school districts to support science learning. We offer district-wide elementary, middle, and high school programs, either virtually or in-person.
We collaborate with a range of partners to innovate in science education. Together, we go further.
Make and use your own Uncle Al’s Hands-On Universe Star Wheels to have a working star map for anytime of night, any month. Find constellations for various latitudes, northern and southern hemisphere, different languages, and even a Kepler Star Wheel for finding stars with exoplanets. Uncle Al’s Star Wheels are inexpensive star maps, adjustable for any time of night in any month of the year. Such maps are also called planispheres. These star wheels were created by the Hall’s Hands-On Universe project, and based on the Lawrence Hall of Science’s Sky Challenger, a set of 6 star wheels, available as a downloadable kit through The Lawrence Discovery Store.
To Use the Star Wheels
2. Note which horizon the constellation is closest to and put that horizon near the bottom.
3. Constellations higher in the sky are closer to the center of the map.
