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 Blood Type Testing that can be used to make predications and communicate their findings to others. It is important to identify blood groups before carrying out a blood transfusion. First, your students assemble red blood cells and antibodies using the colorful templates. Then they use their 3D blood component models to carry out a simulated procedure to test the ABO and Rhesus blood group. The model shows how antibodies are used to clump (agglutinate) red blood cells together and determine the blood type of a sample. Includes enough materials for an individual student to work alone or 2 students to work cooperatively to assemble a paper model. Also includes a comprehensive background information 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 at home, in the classroom or lab.
