#bced Pro-D. The chair gave me time to explain what this thing was , humming in the middle of our circle of 27 mostly unmasked teachers. I said it was a #science project. We had #wildfires which gave us choking smoke....1/ #covid19bc #CorsiRosenthalBox 
...It was built by the #science class. I shared that the #CorsiRosenthalBox can breath in >1000x more air than our lungs so any wildfire smoke, pollution or airborne diseases like flu, or covid is more likely to be caught here before we breathe it in! #bced After I presented 2/
after I presented, a teacher took a pic of it & asked me how to make it. I promised her a link to how to make a #CorsiRosenthalBox so she could make one with her child. Next, the humanities teacher borrowed the #science dept CO2 monitor , &the math teacher borrowed my monitor 3/
They really thought it was cool. So if you are a #bced teacher, build one! Bring it to a meeting, & put it in the middle of the room #CorsiRosenthalBox as a #science conversation starter . "What's THAT?"
"Oh, my #science students made it..."
"Oh, my #science students made it..."
