Ben Bogue demonstrates the petrographic microscope to a young visitor
For the second year in a row, the Geological Sciences Department sponsored two tables at the regional Durham Fair from September 21 to 24, 2017. We estimate that over 3500 people stopped by our tables in the total of 39 hours that we were there.
Our set-up was similar to last year: We had two hands-on displays. The first was ‘What’s inside a Rock.’ For this one we had a binocular microscope where people could look at a rock under low magnification. We also had a petrographic microscope with a camera and an external computer monitor displaying a thin section of the same rock. As people looked through the microscope they saw a rainbow of colors in the thin section due to the effect of polarized light. Nearly every little kid (and most adults) went WOW! THAT’S NEAT! We told them that this is how geologists ‘look inside a rock’ to learn what minerals are present. Everyone was fascinated.
We also had a display of rocks from throughout Connecticut and especially from around Durham for ‘This is Durham 200 Million Years Ago.’ The kids were able to touch a fish fossil from Durham and we gave out samples of muscovite mica, pegmatite, and packets of the three different rock types. We gave away about 1000 bags of rocks and minerals.
For Dr. Evans, it was a pleasure talking with the hundreds of people who stopped by and asked questions about the display. Like last year, Dr. Evans also gave two talks at the Fair: The ‘Geology of Connecticut’ and ‘Climate Change in Connecticut in the Past 20,000 Years.’ Both were well attended with nearly 50 people in attendance for each.
We had seventeen (17!!) Geological Sciences majors volunteer their time to help out. We especially want to thank: Henry Abbott, Ben Bogue, Angie Colella, Emma Colucci, Joe Croze, Kelsey Duffy, Robb Evans, Brenden Hughes, Neal Hulstein, Isabelle Kisluk, Sarah Krzeminska, Chrisette Landell, Corbin MacDonald, Ian Murphy, Sara Poppa, Abbie Underwood, and Nick Zygmont. In addition, we had help from former student Melissa Luna (now working on her Master’s at Wesleyan) and Sarah Krzeminska’s friend Ken Lalli. We could not have had such a successful event without them.
We were invited back for next year’s fair, so if you did not see us there, we’ll be back in 2018. In the meantime, stop by and see us at the Bristol Gem and Mineral Show (http://bristolgem.org/annual-show/) in October!
