Learn about the science behind numismatics at
The Big Cool Science Festival at Colorado College on Saturday,
April 12 from 10 a.m. to 3 p.m. The festival is a free, fun filled
day of hands-on science adventures. There will be live science
demonstrations, tours and engaging activities.
Sam Gelberd, ANA Education Instructor, and Rod
Gillis, ANA Numismatic Educator, from the American Numismatic
Association will have three interactive demonstrations at the ANA
booth located inside the Olin Fishbowl.
- Using safe, simple electrolysis to conserve Ancient Roman
Coins. Learn how to restore and preserve artifacts for future
- A guessing game using a balance/scale and two different coins.
Kids will get to look at two coins and, based on their
observations, guess which coin weighs more. Guess correct and
they'll win the heavier coin! An incorrect guess will still earn
them another cool numismatic prize.
- A display of toned and environmentally damaged/corroded coins.
Information sheets will be displayed about these processes and how
many (transition) metals interact with their surroundings.
After visiting the ANA booth, be sure to check
out the other activity stations located around Barnes Science
Center, Olin Hall, Shove Chapel and KRCC radio station.
