The BioBus is a fully mobile research lab that visit schools and public science events in New York City. Outfitted with state-of-the-art microscopes and run by a diverse team of young scientists, the BioBus is a mobile science field trip where students can use a phase-contrast video microscope to make movies of crawling amoeba, use a scanning electron microscope to image a fly eye, or use a fluorescing microscope to see glowing, streaming plant chloroplast. In 2014, the BioBus visited 88 K-12 schools in New York City, bringing high-quality, engaging education to some 16,000 students, 57 percent of whom were African-American or Latino. Funds from this grant support the continued operation and expansion of BioBus. Over the next three years, Cell Motion Laboratories, the parent organization of the BioBus, will build another BioBus mobile lab and, in partnership with Columbia University, build a “BioBase” community lab in Harlem, which will allow students to continue their educational experiences once the BioBus has moved locations, and expand its educational offerings to underserved students in Harlem.
