About this worksheet
A six-paragraph passage for 4th grade follows electricity back from a bedroom light switch to the power plant. It explains turbines and generators, fossil fuel plants that boil water into steam, wind turbines, hydroelectric dams and solar panels, then the costs of each source. Students answer four key-detail questions and define turbine and generator from the text. A pros and cons table for two sources follows, then an opinion question about a new power plant for their town. The passage has no statistics. It ties to NGSS 4-ESS3-1, and the answer pages quote the text where it helps.
