Fourth graders on virtual field trip witness magic of chemistry

Sandia’s Advanced Materials Laboratory recently staged a remote chemistry field trip for 200 fourth graders, who visited from their screens from five Title One elementary schools in Albuquerque. Researchers conducted the demonstrations after providing kits for the students to make lava lamps, Oobleck, gummy molecules and catapults. The students also enjoyed the ever-popular liquid nitrogen and Mentos demonstrations.

Chemist LaRico Treadwell worked with his laboratory team of postdocs and student interns to come up with fun activities that could be done safely at home or in the classroom. With support from Angela Walde, the team provided material kits for every student. After a short safety briefing, the students got to meet Sandia chemists and to become junior scientists themselves. Activities will be available soon on the Kids Day website.

The Advanced Materials Laboratory opened in 1992 to foster collaborations among Sandia, the University of New Mexico and private companies. Its primary focus is research on the synthesis and characterization of materials and on processing and manufacturing.

POP! GO THE MENTOS — In the photos above, Avi, Eryal, Alyssa and Patricia stand back to watch the resulting volcanic plumes (left); Avi immortalizes a rose by dipping it in liquid nitrogen (middle); and event organizer LaRico Treadwell holds the camera so the students can watch Harold Lee dissolve plastics in acetone under a chemical fume hood (right).
