Getting a Charge out of Electricity

We began our study of electricity this week.  We have learned about Galvani, the scientist that discovered electricity, and Volta, the scientist that was the first to make electricity.  We have begun to experiment with creating batteries using food items, as well as testing for conductivity.  Some of the results are "shocking".

lemon

orange

banana

bread

  

voltmeter

using a 6V battery

  

conductor -metal spoon

insulator- wood

 Some new vocabulary that we have learned is:  alligator clip, LED (light emitting diode), conductor, insulator, voltmeter.  Ask your child about it.  We will continue our tests next week.
