The Siemens Foundation and Discovery Education have launched Siemens STEM Day, a website that includes more than 130 elementary and middle school activities, as well as high school resources designed to support STEM curriculum and instruction with digital content.  Available at no cost, Siemens STEM Day materials emphasize the importance of STEM through standards-aligned, hands-on classroom activities designed to support the development of students’ ability to investigate, question, and understand how the world works within STEM principles. Interactive student activities can be filtered by grade level, category, or career path. The activities explore topics spanning healthcare, engineering, IT, science, math, technology, energy, and manufacturing. Siemens STEM Day also offers Educator Support with five-minute thematic refreshers designed to help prepare for the hands-on activities and make meaningful connections for students. Plus: To celebrate the initiative’s launch, Siemens STEM Day is hosting The Possibility Grant Sweepstakes, which offers schools the chance to win up to $10,000 to go toward STEM education. Eligible educators may enter the sweepstakes once per day through April 28, 2017.
