Testing Face Mask Efficacy Using Sensors Measuring Humidity

Featured Image

Mr. Vandegrift is using a PocketLab Voyager (But you can also use Weather or Air) to show his students the efficacy of face masks. Through data collection and visualization, the students are engaged and curious and want to keep investigating. Check out his YouTube video below. 

Getting students excited about science and relating it to the real world around them is key to buy in from them. Myles Vandegrift gets that. We consider him one of our PocketLab STEM Superstars.

Myles Vandegrift is a passionate middle school science teacher who has been engaging students with his enthusiasm and genuine curiosity about the natural world for more than 28 years. He is deeply driven to connect with students and make science meaningful and relevant to them. He cherishes the opportunity to inspire young people to reach their full potential and believes every student can learn and achieve at high levels with enough time, support, and the right learning environment. Outside of the classroom, Myles connects with students through his work coaching skateboarding and the science olympiad team, and has taken students on expeditions to Catalina Island, Beijing China, Tambopata Research Center in the Amazonian Rainforest of Southeastern Peru, the lost Incan city of Machu Picchu, and Gabon Africa (Operation Canopy distance learning project). Myles also inspires future science teachers as an adjunct professor at Point Loma Nazarene University, which is where he earned his undergraduate degree in biology and MA in Teaching and Learning.

In this video he is using the humidity function of a PocketLab to measure how much moisture (the droplets we have heard so much about) is escaping past a face mask. On the chart logging the data you can see the rise and fall of this level. Replicating this same experiment with masks of varying materials will reveal which masks are most effective.

What percent humidity do you think your face mask lets through?
