A physics educator whose joint classroom experiment uses a cloud chamber to connect particle detection with observable condensation. The chamber’s temperature gradient creates vapor that condenses along ionized tracks. Illumination at a low angle reveals those tracks, letting students investigate naturally occurring cosmic rays with simple optical and thermal equipment.[ref]
