In 2015, Hemlock's Gray Matter Robotics team was founded.  As the STEM program grew, the need for a dedicated space became more apparent. In 2020, the Lockwood STEM Center was built. The KEEL Innovation Center was added in 2025 to provide additonal space for STEM education.

At the STEM Center, students practice a variety of STEM education skills, such as coding, computer-aided design, machining, and fabrication.  FIRST Robotics programs from supported schools also use the STEM Center as a build and practice arena. 

High-school students are able to determine if a STEM career is right for them – whether they are college-bound or entering the workforce right away – by receiving mentoring from professionals in industries such as engineering, farming, and manufacturing. 

In addition, the STEM Center provides a positive and safe environment in which to cultivate academic achievement and instill a sense of pride within students. 

The STEM Center Currently Services Five Local School Districts
