Used in these demonstrations

Tilted air track on a lecture bench with yellow position markers (-5 to 5), two photogates with digital displays, wooden blocks elevating the left end, glider visible as motion blur near center, and air blower connected at right
Safety

Acceleration on an Air Track

A tilted air track with photogates measures transit times to demonstrate uniform acceleration. The glider takes the same time through each photogate on the way up as on the way …
Blue toy monster truck labeled 'Swamp Rat' on a wooden cart with large wheels and a backstop, positioned on a lab bench with a bar-clamped stopping block at the far end

Car on Cart

Demonstrates Newton's First Law: when the cart hits a stopping block and stops abruptly, the toy car continues forward at the original velocity. Students see that a force acts on …
A hand touches the wick of the unlit candle behind a glass plate; the lit candle in front reflects in the glass, making both candles appear lit. A lead brick supports the glass.
Safety

Cold Candle

Demonstrates virtual image formation by plane reflection. A glass plate reflects the flame of a lit candle so that it appears to coincide with an unlit candle behind the glass, …
Plastic tray of dark blue dyed water resting on wooden blocks, with a desk lamp reflecting off the water surface — no magnets present yet
Safety

Diamagnetism of Water

Strong magnets create visible deformations in a thin layer of dyed water, demonstrating that water is diamagnetic — it is weakly repelled by magnetic fields. Students see that magnetic interactions …
Chrome floor fan with wire cage, stationary, showing three metal blades painted green, blue, and red
Safety

Fan Blade Color Mixing

Demonstrates additive color mixing: three fan blades painted red, green, and blue blend to white when spinning at full speed. A strobe light freezes the blades to reveal individual colors, …
Video camera with flip-out LCD screen showing bright circular pinhole images, pinhole slide mounted on wooden block in front of lens, hand holding purple pen near the camera

Pinhole and Inverted Shadow

Students observe the counterintuitive phenomenon where a shadow of an object near a camera lens appears inverted when viewed through a pinhole. Demonstrates geometric optics of pinhole imaging and connects …
Two wooden polarization grids clamped to a green-topped lecture bench with yellow rubber tube threaded through — one grid has horizontal bars, the other has vertical bars
Safety

Polarized Waves

Transverse waves on a rubber tube pass through or are blocked by wooden grids, providing a mechanical analogy for light polarization. Students see single-polarizer transmission, crossed-polarizer extinction, and the surprising …
Three-panel image: (left) Mini Maglite with wooden bar casting a sharp shadow on the wall, (center) round frosted bulb with the same bar casting a diffuse shadow, (right) tall clear filament bulb with the bar held horizontally
Safety

Shadows

Students observe how source geometry determines shadow sharpness. A point source (Mini Maglite) casts sharp shadows; an extended source (frosted bulb) produces penumbra. A tall clear filament bulb shows orientation-dependent …
Standing wave lantern slide shown at two different handle positions: each view shows three sinusoidal wire traces — two traveling waves (top two) and their standing-wave superposition (bottom)

Standing Waves

A rotating overhead-projector slide animates two traveling waves moving in opposite directions and displays their superposition as a standing wave. Students see directly that standing waves are not a separate …
PASCO aluminum air track on a green lab bench with adjustable metal leveling feet, a yellow measurement scale along the track, wooden blocks underneath for tilting, and the air blower unit at the right end

Tilted Air Track

A nearly frictionless air track tilted at an angle produces constant acceleration. The glider bounces off a rubber bumper at the end, and equally-spaced markers along the track enable quantitative …
