An Illuminating Discovery in Gesher
What do you get when you put together lemons, a copper wire, a zinc coated nail, etrogim, and a tiny light bulb? A science experiment! Sarah Montag, Schechter’s Director of Teaching and Learning, brought her passion for science to the Gesher class last week. They began by examining their prior knowledge about etrogim, a timely subject matter since Sukkot was last month. (Fun fact: did you know that the etrog is one of the four “founding fathers” of all the citrus fruit in the world, alongside pomelo, mandarin and papedas? An etrog is not a type of lemon, but rather the other way around!)
Sarah provided students with background information about discoveries using a lemon as a battery. Students worked through the experiment using the steps of the scientific method and then made their own predictions about if this experiment would also work using etrogim. Upon testing their hypothesis, they discovered that the acid in the etrog allows for the transfer of electrons from copper to zinc which causes electricity, just like with the lemons. Success!
