The final gathering of the 8th Annual Rocks Beneath Our Toes (RoBOT) Program was held Wednesday night.
The brain child of Department of Earth and Environment Professor Ethan Baxter, the RoBOT Program brings together local area high school students and BU undergraduates in an effort to learn more about the geology of the area. The students collect and analyze local rock samples and then display their findings at the end of the semester.
This years program was organized by Prof. Baxter and graduate student and Teaching Fellow Emily Stewart. The first step in the program is the collection of rock samples. This took place back in October when Professor Baxter and 13 of his ES 222 Mineralogy students took 20 Acton-Boxborough Regional High School students out on a rock collecting field trip.
Then, two weeks ago, the students came back together to analyze their findings:
The students used the Department’s polarized light microscopes to get a closer look at their samples.
Then, Dr. Joel Sparks helped the students run the X-Ray Diffraction (XRD) system lab.
The culmination of the program took place Wednesday night as the 20 high school students returned to campus and were given special tours of our lab facilities:
First the students, donning special clean suits, toured our clean lab facilities where Department personnel and students prepare samples for analysis.
Then, Dr. Denise Honn led the students through a tour of the Thermal Ionization Mass Spectrometry (TIMS) lab.
Finally, Dr. Tom Ireland took the students through a tour of the Inductively Coupled Plasma Mass Spectrometer (ICP-MS) facilities.
After the tours, the High School students were treated to a presentation of the Mineralogy students’ semester long research on their collected rock samples:
Dean Sapiro joined in as well. Here, her and a student discuss the results of the program.
The final results of the High School students’ and the Mineralogy students’ hard work are now on display in the halls of the Department, on the first floor of the Stone Science Building.
Professor Ethan Baxter gave a talk last Thursday at the University of New Hampshire as part of UNH’s Department of Earth Sciences Brown Bag Seminar. Prof. Baxter’s talk was titled “Linking garnet to water: The Chronology of Dehydration.”

This past Saturday, Professor Ethan Baxter led a group of Boston University undergraduates and area high schoolers on a field trip to take samples of local rocks as part of the the Department of Earth and Environment’s “Rocks Beneath Our Toes” (RoBOT) Program.
Twelve of Dr. Baxter’s ES222 Mineralogy students along with 20 Acton-Boxborough high school students explored several sample sites in the Acton-Boxborough community, collecting rock samples for later analysis. The Mineralogy students carried on into the afternoon collecting samples from sites in New Hampshire, the last of which were outcrops on Dean Virginia Sapiro’s property.
Dr. Baxter and his students will use petrographic microscopes to analyze thin sections from the collected samples over the coming weeks; while RoBOT high school participants perform background research on the geography and underlying geology of the sample locations. Later this fall, the students will reunite at BU to discuss their findings and analyze the rock samples. The participants will then display their findings in a poster session.

On October 13th, Undergraduates enrolled in ES222 “Mineralogy” were joined by Concord-Carlisle High School (CCHS) students as part of the 7th annual RoBOT “Rocks Beneath Or Toes” Outreach Program run by Prof. Ethan Baxter each Fall. Together, students sampled rocks and sediments from several sites in the Concord-Carlisle area and Massachusetts. The field trip was the first of three RoBOT events this semester, the next two of which will bring CCHS students together with BU students to analyze those samples in our mineralogy and geochemistry labs at BU.
