Models are powerful tools for teaching science as they provide useful simplifications of structures and processes, helping to make the unseen seen and the complex simple. First, your students make their paper model of a fetal pig out of the colorful parts. They build the pig and then add the organs to the model. The model can be used look at the anatomy of the major body systems. It covers the nervous system (brain & spinal cord), circulatory system (heart and major blood vessels), respiratory system (lungs and trachea), digestive system (mouth, esophagus, stomach, small intestine, spiral colon, rectum, pancreas, liver, gallbladder), excretory system (kidneys and bladder) and male & female reproductive systems.The model also shows how a fetal pig differs from an adult animal covering the fetal circulation and umbilical cord. Students can then carry out a dissection to see how the parts fit together. It can be used to look at different organ systems and for comparative anatomy. A great way to prepare for a dissection or as an alternative to a real dissection. The Model Making Kit includes enough materials for students to assemble up to 5 paper models working cooperatively. The comprehensive Teacher Resource Guide included provides illustrated readings, activities, key vocabulary and an assessment, along with teaching opportunities for students to Engage, Explore, Explain, Extend and Evaluate their understanding of the concepts presented.
