Lesson 2:1 - Fish Sense
by Nadine Meyer, Aquatic Education Specialist
Chapter 2 of the MinnAqua Leader’s Guide - Fishing: Get in the Habitat! focuses on Minnesota fish. Fish are incredibly fascinating and our Leader’s Guide is filled to the gills with fish information. Chapter 2 houses nine of our 39 lessons. The first lesson of Chapter 2, Lesson 2:1 - Fish Sense is particularly popular.
Download the Lesson
Students touch and hold a fish (or a rubber replica of a fish) to explore the six senses of fish and gain a better understanding of fish behavior. They compare and contrast their own senses with those of fish. When students have become comfortable with handling fish, they apply paint to a fish and print its image on a sheet of paper using the ancient Japanese art form of gyotaku (gee-oh-tah-koo).
Tips & Tricks
Internal anatomy of a fish ear
- Put paint into small dishes and use small paint brushes. This helps reduce the amount of paint students put on their fish, allowing for higher quality print with less smearing.
- If a student puts too much paint on his or her fish, use a piece of scrap paper to do the first and possibly second print. Then the fish is ready for the high-quality final print. MinnAqua keeps blank newsprint on hand for just this sort of thing
- Keep a couple buckets of water close by along with some scrub brushes for the students to use to wash their fish. This will prevent clogged drains and other potential messes that could occur when children are carrying painted fish to a sink for cleaning.
- Keep a set of fish for T-shirt printing with fabric paints separate from the fish used with other water-based paints. Fabric paints dry very fast and usually do not wash off of the real fish or fish replicas very easily.
- Keep a set of rags handy, instead of paper towels for drying fish before using them to print again. This reduces paper water. Make sure the fish are clean of paint before using the rags to dry them off.
- Be aware of wasp season if using real fish outside. If wasps are a problem, use one real fish to show the fish senses and use rubber fish replicas for the gyotaku activity.
Rubber fish replicas for fish printing can be found in a variety of places. The only company that sells 5” rubber bluegill replica individually is Acorn Naturalists. Their website is http://www. acornnaturalists.com/. Other companies sell rubber fish replicas; the replicas are generally sold in sets with ocean and freshwater species.
