Experiment 2.0: Electroscope Do Now: How does an object get positively charged? (pick one) a) gain protons b) lose protons c) gain electrons d) lose electrons In this lab, you will be charging a rubber rod by rubbing it with rabbit fur, and charging a glass/plastic rod by rubbing it with silk. 1. Based on the triboelectric (see last page) series, what charge does each object acquire? Item Rubber Rod Charge Item Rabbit Fur Charge glass/plastic Rod Silk 2. Take the charged rubber rod and touch it firmly to the electroscope charge sampler (without tipping over the electroscope). Observation: ___________________________
