We designed a low cost modular assembly using an inexpensive laser pointer to study interference and diffraction in introductory physics. This was in response to our desire for the students to have a hands-on laboratory experience during…
A low-cost optics kit developed for remote instruction. The kit uses 3D printed parts, 38mm diameter optical components, a cloth tape measure and a flashlight from Harbor Freight. Cellophane tape is placed on the flashlight for diffusion…
Rotational equilibrium balance kit. Balance kit using 3D printed parts and hardware store items. Ruler:…
A clamp to hold the photogate on the older PASCO air tracks. (Black plastic end caps) Students would bump into the photogates on the stands and have to reset the positions. The clamp secures the photogate to the air track. I used nylon…
the resonance tube is used in the speed of sound experiment. Students use an app to generate audio tones. The smartphone is placed at the open end of the tube and the piston is slid back and forth until a resonant tone is heard. The…
Using the rotational equilibrium kit https://www.thingiverse.com/thing:5349742 , we add a small magnet to one side of the balance. Under that magnet, we placed a wire coil on a jack stand. The stand allows the user to raise and lower the…
Notes taped to the door did little to stop students from entering the lab when exposing film in the lab. The door guard was created to be an obvious indicator. The students can no longer claim, " I didn't see the note on the door". The…
