Mr. Watson Teaches 7th Grade Students How to Separate Water
Mr. Watson's 7th Grade Classes have spent this week learning how to separate water molecules into two elements using electrolysis.  Using water, test tubes, batteries and a flame, students setup the experiment by submersing water filled test tubes into water and exposing them to electricity, using 9 volt batteries.  Students watched as the water in the test tubes were transformed into hydrogen in one tube and oxygen in the other. Then, using a flame, students ignited the hydrogen in the test tube, producing a "pop." 

This experiment shows how elements are not created or eliminated, but changed, as what happens in nature.  Students also learn properties of hydrogen, as well as the process of electrolysis.
