Kohl’s Corp. plans to contribute $1.5 million over three years as a grant to Discovery World. The funds target increased access to science, technology, engineering and math education for children and families in Milwaukee’s most vulnerable communities, according to a news release from the Menomonee Falls-based retailer. Discovery World, a family-friendly science and technology center on Harbor Drive near Milwaukee’s lakefront, will allocate the donation toward two main efforts. Students from more than 250 qualifying schools can visit Discovery World to participate in the Kohl’s Design It! lab for free. The lab offers a hands-on, educational program that aims to help students and families harness technology. At least 50 percent of the student population lives in poverty at qualifying schools, the release says. The mobile lab will also travel to organizations in the Milwaukee area and qualifying schools to introduce families and students to STEM fields through demonstrations and hands-on activities.
