Models are powerful tools for teaching Science as they provide useful simplifications of structures and processes, helping make the unseen visible and the complex simple! Using the ready-to-use materials provided, students first assemble a model to represent the Liver & Spleen as an aid to develop questions and explanations. They will then generate data and observations that can be used to make predictions and communicate their findings to others. Kit includes enough materials for students to work cooperatively to assemble 5 paper models. Also includes a comprehensive Teacher Resource Guide providing opportunities for students to Engage, Explore, Explain, Extend and Evaluate their understanding of the concept. Satisfies NGSS Standards which encourage students to develop & use models to represent structures, systems & processes. Perfect for use in the classroom, lab or at home
