"It's hard because you have to do all the steps," Sydney Spencer said, as she took a break from assembling and testing her team's vehicle.
Arbutus resident Lisa Whittington, who works in human resources information systems at Northrop Grumman, nominated Relay Elementary School for one of the presentations the defense company gives through its DiscoverE program.
The company has done this outreach with elementary, middle and high schools since 1990, visiting more than 2,100 schools, according to a release from the company.
Since March, Northrop Grumman has sent engineers to 116 schools, primarily in Maryland, using the demonstrations to build interest in the profession.
"They get to see what a real engineer would do," said Whittington, whose daughter, Christina Lawson, is a kindergartener at Relay Elementary. "It helps them with problem solving."
Last year, the Northrop Grumman presentation went to students in pre-kindergarten through fourth grades and Whittington said her daughter now "tinkers" with things at home, even wanting to help fix a broken vacuum.
A rocket launch scheduled at the school the day of the DiscoverE program was canceled due to an impending storm.
Though they couldn't blast off, the students spirits weren't dampened.
Fatima Parveen examined her team's car closely and admitted the task came with some pressure.
"You got to do a lot of measuring and you might mess up," she said.
