Life Science Reading Comprehension Passage and Questions: Bioluminescence (Fillable PDF)

This very engaging life science reading passage about Bioluminescence: how living things produce light through chemical reactions. It explains how glowing organisms use light for survival, including communication, defense, camouflage, attracting prey, and escaping predators. Examples include glowing plankton, anglerfish, squid, jellyfish, fireflies, glow-worms, fungi, microbes, and marine bacteria. It also explains the science behind firefly light, especially luciferin, oxygen, and luciferase, and shows how scientists use bioluminescence in labs and possible technology.

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.
