        Benefits of Using a Human Model

        In this video segment from Teaching Middle School Life Science, teacher Monica Chrambach leads her seventh-grade students through an activity using a model of the digestive system. Chrambach explains that one benefit of using models like this one is that it helps students remember the message—in this case, that enzymes cut up food at a chemical level. By allowing students to engage with models in a fun and messy way, she is able to teach subjects that may otherwise be too abstract or complex to be meaningful at this age.
