Third Graders Become Crayfish Experts and Teachers

Third grade students in Ms. Roqhuett’s class at Robinson Barracks Elementary School took on the roles of scientists and teachers this month as part of their FOSS “Structures of Life” science unit, becoming experts on crayfish and sharing their knowledge with younger students throughout the school.

The students explored how crayfish use their body structures to survive and protect themselves. Then, during their science block, they led 10-minute presentations for Pre-K, kindergarten, first-, and second-grade classes.

Arriving prepared and professional, the third graders introduced themselves confidently and quickly captured their young audiences’ attention with fun facts and questions about crayfish. Using the Elmo and Smart Board, they displayed handmade posters and visual models, explaining the function of each body part, how to identify males and females, and how to safely handle live crayfish.

The hands-on learning experience supported Department of Defense Education Activity (DoDEA) third-grade standards in both science and English language arts. It also helped students practice communicating scientific ideas clearly, using technology effectively, and collaborating as a team.

“I liked giving my speech to the preschool class because they asked a lot of questions that I could answer,” said third grader Logan.

Adam added, “I liked seeing the joy in the kindergarten class and how my sister watched me. I also liked using the Elmo to show the crayfish.”

“I liked seeing my little brother while I was teaching,” said Jack, while Brayden shared, “I liked seeing the kindergarten students pick up the crayfish and not scream. They really liked it!”

Ms. Roqhuett said her students “felt like real teachers,” adding that their enthusiasm and confidence shone throughout the presentations.

Through the project, the third graders not only deepened their understanding of life science but also developed valuable skills in leadership, communication, and teamwork—proving that learning is even more powerful when it’s shared.
