CRYSTAL LAKE – A group of local engineers returned to the classroom this week to teach students at Hannah Beardsley Middle School about opportunities in the industry.

The school's third annual "Discover Engineering Week" program, included visits from engineers at Northrop Grumman, Motorola Mobility, Baxter & Woodman, General Kinematics, Cideas Inc., and Sargent & Lundy.

The program is designed to spark interest in engineering and encourage students to take courses in science, technology, math, and engineering.
