DeKalb West School students enjoyed their second visit in as many years from the STEMmobile science lab, a $350,000, 53-foot mobile science laboratory designed to provide an on-site educational experience for pre-K through eighth-grade students last week. The mobile classroom brought state-of-the-art equipment and technology to the parking lot at DWS, and allowed students to learn about science in creative and hands-on ways. DWS Principal Sabrina Farler told the board of education at their last regular meeting that the STEMmobile would give her students a unique chance to learn.
