Karsyn and Mrs. Block light methane bubbles!
Karsyn, Kacie, and Lydia are assisted by Chem Club member Leslie Rush.
Mr. Mike Brouwer’s 7th grade Science class from Mayo Junior High recently visited Mrs. Brett Block’s PCHS Chemistry Lab for a lesson in energy and how it affects electrons in an atom. The PCHS Chemistry Club were on hand to assist in a Flame Test Lab where wood splints soaked in various chemical solutions were burned to identify them based on their signature colors – blues, reds, oranges, and pinks. They also viewed light energy given off by different gases trapped in a tube as electricity was sent through to excite the electrons. Finally, Mrs. Block gave a lesson on the methane gas used in the lab burners by creating methane gas bubbles which she ignited while the students held them in their hand. Chemistry Club is a PCHS organization designed to be champions of science. They are available to visit local schools or arrange a visit at the PCHS Chemistry Lab.

Triston and Mrs. Block....
Faith is not afraid....
Salem complained after this one - said his knuckle hairs got singed! (that means superficially burned)
electricity through the spectrum tubes show a signature color for that gas...
Mayo students view white light through the spectroscopes to see the wavelengths...
