Students comparing the distance between the Earth and the Moon

Saturday Morning Astrophysics kicked off the semester with students creating a scale model of the recent solar eclipse, proportionally scaling the sun, Earth and moon and the distances between them.

Based on a five-foot diameter sun, the Earth is about the size of your eyeball. The moon is only the size of a pearl on the head of a pin about 30 cm away.

Going outside, students found that at this scale the Earth-moon system are a whopping 450 feet from the sun!

Lewis Cass High School visits Purdue Labs 

Lewis Cass High School visits Purdue Labs

Outreach hosted Physics students from Lewis Cass High School for a visit to two Purdue research laboratories, PRIME Lab and the Purdue-1 reactor (PUR-1). PRIME Lab (Purdue Radionuclide Measurement Laboratory) is a particle accelerator and mass spec facility whose primary function is the measurement of nuclides and rare trace elements - this kinds of isotopes produces, for example, by cosmic rays striking the Earth.


Lewis Cass High School visits Purdue LabsPUR-1 is Purdue's nuclear reactor; the only nuclear reactor facility operating in the State of Indiana. Students learned about various types of radiation, and how activated nuclei can be created and analyzed in elemental research.  They then got an up close and personal tour of the reactor itself!


What the students said:

"The visit to Purdue was something that I will never forget. Learning about particles in a way where I can actually see how scientists got their conclusions instead of just listening to a teacher talk about it really helped me understand. The experience was amazing."

"The tour taught me a lot about the science of atoms, radiation, nuclear reactors, and the particle accelerator. The Alpha Gamma guy made an impact on my career thoughts and view of science. His explanation of how related radiation is to so many things expanded my thoughts of going into a science major."

Ramblers Science Club 

Physics and Physics Education service learning students prepared inquiry-based activities for elementary students for Saturday science clubs.  Among the concepts that students explored were properties of color and light, heat and temperature, and forces.  Students learned how combinations of colors can be used to create other colors.
