Practice classification and building dichotomous keys in an engaging way with your students using realistic freshwater fish samples! Great for an introductory activity or reinforcement and review of the concept. Includes several activity options that will accommodate a wide variety of learners. 14 detailed and realistic illustrated freshwater fish sample cards provided (color and black & white).

Want more? Try the Evergreen Set or this dichotomous key research and art project.

This activity introduces the concept gradually, first using a pre-made dichotomous key in the identification process. Then they have the opportunity to create their own key with a limited sample size, before using all of the samples to create a more in depth dichotomous key.

Activity Options:

Option 1: Students work through the provided dichotomous key to identify 8 different coniferous tree samples. Options for individual practice, small group and station rotations!

Option 2: Students create their own dichotomous key using the 6 bonus sample cards. This makes a great lab station for small groups.

Option 3: Students use ALL 14 tree samples to build their own dichotomous key.
