Summer Camp 2024: June-Aug. 2024

Astronomy and Astrophysics

  • Led by Carissa J Lewis
  • Grades 5-9


Take an out-of-this-world journey through outer space and explore the universe’s wonders. Explore the fascinating secrets of the solar system, home to more than just planets. Learn how to measure the distance to stars and “hunt” for exoplanets like a real astrophysicist. Create a timeline for a star and understand how the sun compares in color, size, and age to other stars in the universe.

Through many hands-on activities, discover the shape of the universe, how we analyze both the light and dark spaces of the universe, and how relativity works and when it matters. Our universe’s beauty and grandness will open new doors to our imagination and mind.

Led byCarissa J Lewis

Since she was a small child, Carissa has always loved math and wanted to know why things they way they are. She loved watching science-related TV shows and enjoyed popular science programs. Once in college, she found her love in Astrophysics. The field encompassed her two passions perfectly: mathematics and many unanswered questions. Both assured she will remain busy for the rest of her life!
Carissa believes math should not be an obstacle to learning physics, astronomy, or both if appropriately taught. She has taught the subjects to all ages; from young children to college students in classroom setting and privately. She also runs an astrophysics outreach website:

Carissa earned her B.A. in Astrophysics with a minor in Nuclear Engineering from the University of California in Berkeley.
