    Science Olympiad is open to any 6th-9th grade MCPS student, including area  homeschool students!


    A little History

    The MCPS Science Olympiad team was created in the 2020-2021 school year. The team worked together virtually to learn about their events, problem solve, and compete against 19 other schools at the 2021 Virginia Science Olympiad Leibniz Regional for Division B.

    The tournament involved events that challenged the teams' academic knowledge, engineering and design, analytical analysis, reasoning skills, and collaborative ability.

    Popular Events

    • Life, Personal & Social Science
      • Disease Detectives

  • When does the season start and end?

    Posted by:

    The season will begin mid-September. The season usually ends the last week of March. The season can run until the end of April, depending on tournament results.

    The first part of the season is preparing for local and regional tournaments. Then we compete after Winter Break. After our competition, if we are selected to move on, we will work to compete in the State tournament.

    If our team ends at the Regional tournament level, we work on preparing for the next season, fixing our projects, and hosting Family Science Night.

  • What are the requirements to be on the team?

    Posted by:

    The only requirements are personal skills that will allow you to be successful. Team members must be able to follow directions, be independent, responsible, dedicated, timely, detail oriented, and collaborative.

    Students should have a strong desire to learn science.

    These skills are imperative for the success of our team as a whole, because students will be working in partners or small groups, actively researching event(s) information on their own (with support), learning the rules for their event(s) (with support from coaches), and will be traveling to and from different event rooms or buildings (if we are in person).

Ms. Carey Hancey

Hello! I come to Manassas City Public Schools to give back to the district that laid my academic foundation. It is true that I attended Baldwin Elementary School, Dean Middle School (yes, it was once a middle school!), and Osbourn High School. From there, I went to Virginia Tech.

I have a bachelor's degree in chemistry and biochemistry with a minor in biology from Virginia Tech (Distinct Honors, Commonwealth Scholar). I continued my education for six years as a doctoral candidate in biological chemistry at Penn State University. At Penn State I taught chemistry lab while researching enzymology and kinetics. This project was a collaborative effort with Stanford University and the NIH.

I truly have an immense passion for the sciences and math. I have instructed many gifted students in both subjects. In doing so, I know the importance of critical thinking skills and the ability to be innovative.

I am very excited to be able to lead the IMS program and share my expertise in both content and research with these talented students.

When I am not coaching or instructing, I enjoy college football (GO HOKIES!!!), cooking, drumming, traveling, and strength training.
