Caltech scientists, working with local high school science teachers, have created a program called Juice from Juice that teaches concepts related to solar energy in the disciplines of Chemistry, Biology, Physics and Engineering. The main experiment for Juice from Juice is building a dye-sensitized solar cell. This supplemental kit expands upon the related engineering, chemistry and biology concepts of that kit by having students build their own water-splitting device. The students must construct the device themselves and then can watch water transform into hydrogen and oxygen gases before their eyes. This concept of storing energy in chemical bonds relates directly to photosynthesis. This kit can also be used as a jumping off point for a discussion on fuel cells and hydrogen energy storage.
For a class of 30 in pairs (or slightly more with groups of 3). Once devices are made, they are reusable. Extra sodium sulfate is available in a refill kit to run subsequent reactions with the device.
