In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow. Learners will use a balloon or a disposable glove fingertip to alter the flow of water of a drinking straw. This is part one of a more complete model of a heart ventricle (as described in another DIY Human Body activity included in the related link at the bottom of this page). Step-by-step instructions are included with photos along with safety recommendations. Activity guide includes a "What's going on?" explanation and connections to relevant science concepts like blood oxygenation, valve function in the circulatory system, and heart murmurs.
