Sometimes studies in the Elms end with a large culminating event. Sometimes we celebrate among ourselves. Such was the case with electricity. This week we made a party line with ten and a half old fashioned land line phones (G.L. only wanted the talking half, not the listening half).
Students had to apply what they knew about series circuits and polarity, conductivity and short circuits in order to get the system going. Even then, we had to do a lot of trouble shooting. Each pair of Elms got their own phone working and then added it into a larger circuit. Larger circuits then joined together.
We hope to have a chance to chat with the Tamaracks on our phone soon. (Yet another good way to solidify our learning -- teaching others).
