Pasadena Sister Cities welcomed five students from Jarvenapaa Lukio (high school) in April 2018. The students were accompanied by their physics/chemistry teacher and their math teacher. Their trip focused on science with a tour of JPL and Mt. Wilson Observatories and a visit to the California Science Center, Page Museum and LACMA, and to Caltech. Many thanks to their host families: the McConnell, Harris, Miller, Molz, and Saviano families.
