A look inside the science classroom at Las Cruces High School in 1965, where H.E. Alexander, known to students as “Mr. A,” demonstrates how to measure the percentage of oxygen in the atmosphere using a eudiometer tube while Bill Coleman records the data. Looking on are Celia Haas, Mary Alice Puga, Laura Hanna, Kirstan Schell, Mike Dennard, Linda Bailey, Kent Williston, Lou Ann Needham, Allen Orean, Frank Mejia, Dorothy Myers, Neil Loomis, Jerry White, Jack Saunders, James Wheeler and Richard Carlson. Captured in the 1965 LCHS yearbook, the photo is a great reminder that hands-on learning and a little scientific curiosity have long been part of the Las Cruces High School experience. This is Las Cruces Public Schools, then and now.
