K-12 educators may enjoy Siemens STEM Day, a program providing resources to energize the future of the STEM field. Readers should not be fooled by the name; the wealth of activities can also be formatted into a curriculum that stretches beyond one day. Educators will want to begin with the Train the Trainer Toolkit. The five-minute video and three-page handout introduce users to the program and provide tips on how to best implement it in classrooms. Next, explore the various offerings under the Educators tab, where resources are divided into three pages: Career Profiles (short videos profiling various Siemens employees and their work), Activities (sortable by category, career path, and grade), and Educator Support (downloadable "five-minute refreshers" on various science topics). This program is supported by the Siemens Foundation, which seeks to "clos[e] the opportunity gap for young people in the U.S. when it comes to STEM careers," as well as Discovery Education.
