Fishy Science

Water, water everywhere . . . and yet fish get thirsty. Why? Through observation and experimentation, students learn the answers to that question and many others in this four-lesson curriculum on how fish swim and breathe, their sensory features, and their adaptation to water. Units can stand alone or be presented in sequence. Among the activities are

  • identifying body parts of fish
  • adapting a quarter to enable it to float
  • detecting carbon dioxide in exhaled air
  • exploring the breathing mechanism of fish
  • observing fish for color vision


The teacher manual includes lesson plans, camera-ready student handouts, and information on additional resources.

Fishy Science was developed by faculty and staff of The Ohio State University as part of the Science Alive 4-H School Enrichment Program.
