You probably know about the tiny animal called a mole. But, you may not have heard of a chemistry mole.
I visited Galena High School this morning to learn about the equation.
The sun wasn't even up and the hallways were packed at Galena High School. "IIt's a little early, but so worth it because there are so many things to do," says student Casey Cummings.
Hundreds of teenagers came out for the celebration of moles.
We asked Paul Travis Lathrop who was dressed as "the mole" to tell us about the equation.
"A mole is unit, have you heard? It's six times 10 to the 23rd," he says. "That's six with 22 zeros at the end. It's much to big of number to comprehend."
To help students better understand the theory behind a "mole," chemistry teacher Nancy Greenhalgh organized a local version of the national event.
"The students rotate through several stations, one of which is singing, you can hear behind me. They go to mole'lympics and who wants to be a mole'ionaire," she says.
The event also includes mole bingo and the infamous mole sculpting.
"Here at mole sculpting we give each person a piece of paper and they figure out a math problem. Then they tell us how much foil they need and sculpt a mole out of tin foil," Greenhalgh says.
And the fun dosen't end there.
"It's a day when wearing a Burger King hat is acceptable...well, for extra credit points."
Extra chemistry credit is what the day is all about...and the excuse to eat a cinna"Mole" roll.
Organizers say today's event had the biggest turnout so far, with more than 300 students.
Galena High School has been hosting "Mole Day" the past four years.
