Science Reading Comprehension Passage: Eel Power (PDF)

Science Reading Comprehension Passage and Questions: Eal Power (PDF)

This very engaging science reading passage is about electric eels and how their natural electrical pulses can make holiday lights flicker.

More specifically, it explains how electric eels use special cells called electrocytes to produce electricity for sensing, communication, hunting, and defense. It then describes how aquariums in Japan and Utah use safe equipment, such as aluminum panels and wires, to collect the eel’s brief pulses and make Christmas tree lights flicker. The passage also introduces the broader idea of bioelectricity, or electricity made by living things.

This passage is designed to bridge the gap between science and literacy through strengthening reading comprehension and sparking scientific curiosity in middle school students. The passage blends English Language Arts skills with accurate science content that supports NGSS classroom practice. Ideal for interdisciplinary learning in ELA and Science. Suitable for Grade 9 review, too!
