Last Monday, fifth graders used balloons to move static electricity around the room. We learned that static electricity is the result of electron movement and buildup in certain objects. Students used friction (by rubbing the balloons on hair or carpet) to add electrons to their balloons, then stuck them to all sorts of surfaces: the wall, glass windows, each other, etc.. Much to the teacher’s surprise, we also learned we can build up a charge in a pencil and stick it to the wall. (Not recommended to try at home! But so amazingly cool!)
Today, we visited the Springfield solar farm. We learned from one of Springfield Utilities’ experts about the role the solar farm plays in generating Springfield’s electricity. We also learned about other renewable sources of electricity like wind power and nonrenewable sources like natural gas turbines. The students were particularly interested in how the solar farm’s 40 acres is impacted by natural phenomena (rain, snow) and wildlife. Fun fact – this solar farm alone can power over 900 family homes!
