Fourth Grade Marine Biologists
In fourth-grade science, we are engaging with the Next Generation Science Standards (NGSS) practices, particularly the practice of modeling, during our sea turtle unit. Students took on the role of marine biologists, studying sea turtles in a hands-on and immersive way. After reviewing the characteristics of major animal classes—fish, amphibians, reptiles, birds, and mammals—students determined that sea turtles belong in the reptile group. They then used realistic sea turtle models and a dichotomous key to identify the eight species of sea turtles, honing their observational skills and ability to follow precise scientific procedures. Modeling is a critical scientific practice in this unit. Students learned the anatomy of sea turtles and applied that knowledge by creating their own realistic models. They further explored the sea turtle lifecycle by simulating it with water, sand, and sea turtle toys, gaining a concrete understanding of each stage. To investigate the concept of species adaptation, students modeled sea turtle jaws using tools like scissors, pliers, and tweezers to mimic how different species have evolved to eat specific foods. By engaging in these activities, students learn how to use, create, and analyze models—essential scientific skills. This hands-on approach to modeling allows them to visualize complex systems and processes, helping them better understand the scientific phenomena they are studying.
