This year, i decided to reexamine my potato-roasting method from the ground up with the idea of completely maximizing that crisp-to-creamy contrast in each chunk of potato, testing and retesting every variable, from cut size to potato type to boiling and roasting methods. Potato juice contains many water soluble chemicals that may cause a chemical reaction with one or both of our electrodes for this experiment we use: a fresh potato. The mission of the montana state university (msu) seed potato certification program is to certify montana grown seed potatoes and conduct research to improve potato quality and testing methods. The effect of osmosis in potato cells with different concentrations of sucrose solution aim: to test the effect of different concentrations of sucrose solution to osmosis in a potato cells by putting potato pieces in test tubes of water containing different concentrations of sucrose solution. A potato battery project is the last in a series of fruit and veggie battery projects included on this site many versions are available, but unless you want to get fancy with the voltmeter, fruit batteries make great science projects for kids since they are both inexpensive and relatively easy to perform.
