Classroom Spotlight: Chemistry teacher provides 'hands-on' learning in safety

Chemistry experiment

 

 

During the first week of school, MCHS science teacher Doug Brown gives his chemistry students a truly “hands-on” learning experience in safety training.

Brown illustrates the importance of safety in science class (being conscious of wearing loose clothing, making sure hair is pulled back, etc.) by having students wet their hands, scoop a handful of soapy water infused with natural gas, and hold at arm’s length.

Next, Brown touches the bubbly concoction with a lighter.

The result: an impressive and beautiful flame momentarily rising from the student’s hand.

“It’s a safety exercise, but really it’s more about the ‘Wow’ factor,” Brown said.

By wetting their hands, students create a vapor barrier that keeps them safe from the flame.

Brown has been conducting the captivating experiment each year since he came to MCHS, and his students seem to appreciate the spectacle.

“I thought it was really pretty cool,” 11th grader Jordan McCarty said.
