Snotty Nose

Our bodies produce snot, or mucus, that we blow from our noses. In this activity, learners will create a model of how snot works and will explore how it keeps our bodies healthy. While messy, this model using a small broom or brush and simulated snot does a good job to show learners the importance of mucus in protecting our lungs. Step-by-step instructions are included with photos. Activity guide includes a “What’s going on?” explanation and connections to relevant science concepts like cilia, nose anatomy & function, and how mucus prevents sickness.
