Diffraction Apparatus, Used to map light intensity versus position for many-slit geometries, Slits are made by depositing metal film on glass, creating extraordinarily clean slits with fully opaque blocking areas.
Eudiometer, Demonstrate the combining volume ratios of gases, Platinum electrodes included, Long, sturdy glass tubes have platinum electrodes sealed at the closed end with a 2 mm arc gap, Tubes are marked with a permanent brown scale in 0.1 or 0.2 mL divisions, Size: 100ml
KidWind Solar Thermal Exploration Kit, modeled after a domestic solar water-heating system. Explore variables such as box color, light intensity, tube design, rate of water pumping, and amount of time it takes to heat the water
