In this "O-"fish"-ial" research project, third-grade students use multiple resources to research several fish species, write a research paper and develop a PowerPoint presentation to communicate their findings. In addition, students actually examine these species up close with samples from the local market, and then conclude the project with a celebratory fish-tasting party. Best of all, students not only learn about habitats, ecosystems, and food chains, but also incorporate the science-process skills of observing, classifying, communicating, inferring, predicting, and measuring into this inviting "menu" of learning!
