Fairfax County schools will host two upcoming events for students interested in science, technology, engineering and math.

On Saturday, middle and high school students, parents and teachers keen to learn more about future trends in STEM-related fields can gather at Chantilly High School from 9 a.m. to 2 p.m. The expo will include presentations on how to prepare for a STEM career from experts from the CIA, Northrop Grumman, the FBI and Micron Technology. Exhibitors will also provide students with information on businesses, industries and educational opportunities involving technology, engineering, math and health and medical sciences. Those interested in attending the expo can register here.

On March 1, students from the elite Thomas Jefferson High School for Science and Technology will hold a STEM conference at Hughes Middle School from 8:15 a.m. to 3:30 p.m.

The event, hosted by the non-profit student group Project BEST, which stands for building excitement for science and technology, will include hands-on activities for interested middle school students.

This year’s Science Innovation and Inspiration Youth Conference will revolve around three themes: neuroscience, the mechanics of physics and civil engineering.

Students will be able to learn more about biopsy techniques in brain surgery, how to design and build bridges and the effects of momentum using tools including bicycle wheel gyroscopes. Middle school students and parents can register for the event here. Admission is limited.
