K-12 PhysAstro Outreach with Dr. David Sederberg
Story by David Siple
The philosophy of Physics and Astronomy Outreach at Purdue focuses on creating opportunities for K-12 students to learn and develop enthusiasm for engaging science, and providing high-quality professional development for K-12 teachers, in addition to collaborating with faculty to leverage resources and expertise for broader impact, enhancing science education in classrooms and across the community.
Student voices: Moments that made science click from AstroCamp 2026
Through hands-on lessons, classroom visits, camps and community programs, students saw physics and astronomy become something they could touch, test and imagine themselves doing.
“Building a cloud chamber to detect particles was incredible. I never imagined we could actually observe subatomic particles with something so simple.”
“I learned what the scale of the solar system truly means. When we walked it out physically I felt amazed at how isolated Earth really is.”
“AstroCamp 2026 changed my attitude toward science completely. Before I thought it was too difficult and abstract, but after these workshops I see it as something I can actually do.”
“The Purdue [AstroCamp] team inspired me to take science more seriously. Seeing young people from a top university so passionate about their field made me want to reach that level too.”
“The [AstroCamp] sessions changed how I see my future. Before the camp I did not know what I wanted to study; now I am seriously considering physics or engineering.”

Saturday Morning Astrophysics
Physics and Astronomy’s Saturday Morning Astrophysics at Purdue (SMAP) is a premier outreach program that offers live monthly Zoom sessions for students in grades 8-12, not only locally but around the globe. We currently host students from 34 states across the US, and 3 other countries. Physics and Astronomy faculty and guest astrophysicists present background and breakout room activities on space, cosmology, historical and cutting-edge discoveries, exploring engaging topics beyond the typical classroom curricula. Our recorded SMAP sessions and written lessons are featured on YouTube.

AstroCamp 2026 in Medellín, Colombia
Outreach coordinator Dr. David Sederberg led Purdue Science grad students Trevor Erwin, Dillon Hasenour and Danielle Dickinson, taking our SMAP program on the road again to Medellín, Colombia, for AstroCamp 2026. The group presented The Universe in Color for 30 middle/high school students, searching for exoplanets, making impact craters, and learning how to date terrains on Mars. Three days of engaging astro fun and a lifetime of impact for these eager future scientists and potential Boilermakers.
K-12 Classrooms
Classroom Calls, are opportunities to take PhysAstro Outreach to the classrooms to provide support for teachers and interact with and engage students in their own learning environment.
At the invitation of Ms. Poletti’s class at Orchard School in Indianapolis, we demonstrated how astronomers are able to identify the elemental composition of start through techniques of spectroscopy. In conclusion, we dazzled students with the “Electric Pickle,” exciting sodium atoms in the brine, similar to the emissions from excited atoms in stars.

At Towne Meadow Elementary in Carmel, grad and undergrad PhysAstro volunteers led our 50 Balls of Clay lesson, in which students create an Earth-Moon model from PlayDoh, in the correct proportion of both diameter and distance between.

West Lafayette Assisted Living
With the leadership of grad student Braden Garretson, and officers of the Purdue Astronomy Club at the ready, Outreach presented two programs at West Lafayette Assisted Living. Residents set up an apparatus to explore Why Are Sunsets Red and Skies Are Blue. In our second session, The Sun in Science and Lore, residents learned how astronomers can detect the elemental composition of stars by analyzing the light they emit.

With the goal of every Purdue student having the opportunity to view night sky objects through a telescope, our Boiler Gold Rush hit the spot, welcoming freshmen Boilermakers during their first week on campus.

Physics on the Road
Our Physics on the Road shows give us a chance to impact large audiences with interactive exhibits focused on teaching the fundamentals of physics. Outreach volunteers rolled out our Force and Energy Show at Pine Village Elementary, with our rocket cart, inertia carts, vortex canons, flame vortex, and more. Of course, what show would be complete without the ping pong ball canon as a finale?
Physics Inside Out
We give our annual five-day summer workshop for middle schoolers the name Physics Inside Out, with the theme of providing participants a look at the diverse range of topics in physics and astronomy. The mix of lessons currently includes The Physics of Climbing, giving the inexperienced their first time on the climbing wall at the France Cordova Recreational Center, and the experienced a chance to hone their skills, learning about gravity, friction, levers, and center of mass. Also in the mix, our students are like to find sound and music, heat and temperature, nanoscale fabrication of graphene, and some astrophysics.

High School PhysAstro Tours
We love visitors, and one-on-one interactions with local high school students and teachers present an opportunity for recruitment of future Boilermakers. Dr. Matt Carlson recently brought is honors physics classes to the Department to learn about research across several fields. They hit PRIME Lab, the PUR-1 nuclear reactor, and got a demonstration of how students in Professor Zeng’s lab create a monolayer of carbon atoms in the form of graphene. What a day!

Teacher Workshops
Presentations at this year’s HASTI (Hoosier Association of Science Teachers) included the Searching for Exoplanets computer simulation and Making and Using a Cloud Chamber at Purdue's Indianapolis campus, which helps us serve our mission of providing high-quality professional development for educators. Our cloud chamber workshop provided each teacher the materials to make four cloud chambers to take with them for their own classroom use.

On the Road with Style
None of the highlights of 2025 was the replacement of our aging passenger van, complete with wrap, and the wrap of our existing Road Show cargo van. Branding and visibility go a long way in recruiting upcoming Boilermakers around the state.

Interested in Knowing More?
Purdue Physics and Astronomy Outreach makes Classroom Calls, providing resources and expertise for the K-12 classroom teachers. Whether we provide a "Scientist on Site" for a classroom talk and demonstration, support for lesson design and implementation, or work with teachers to provide a novel learning experience, Physics and Astronomy Outreach is eager to spread our enthusiasm for learning science.
