Electroscopes don’t work well in humid/rainy weather. It is so sad. On Wednesday we were using an electroscope. The weather was cloudy and humid. The electroscope didn’t work well. It barely moved. Mr. Calvert said that it works great in dry weather. He said that it goes up so high. The electroscope works when you rub the wool against the pipe. All the electrons go into the pipe. Then when you move the pipe closer to the electroscope the electrons in the electroscope move down into the jar because electrons stay away from other electrons. In the jar they go on the foil strips. On the foil strips the electrons move away from the ones on the other strip causing the strips to move away from each other. Water is very conductive so when it is humid the water in the air takes the electrons so the electrons don’t go into the jar. I hope we do it again on a dry day to see what the difference is.
