NIST’s Physical Measurement Laboratory (PML) participated in the USA Science and Engineering Festival in Washington DC, offering interactive demonstrations to promote STEM education. Highlights included:
– Laser tracker system demonstrations showing how NIST supports the instrument through standards development
– Photogrammetry technology explaining dimensional measurements on familiar landmarks
– Popular solid-to-gas sublimation demonstration with dry ice, allowing students to observe the transition from solid to gas state
PML scientists reported positive reactions from students, with many expressing wonder and excitement. The event provided valuable hands-on learning experiences and helped inspire the next generation of scientists.
