"The Challenge was an excellent experience. I've learned so much through studying and participating in the competitions that I feel I'm extremely prepared to take on Chemistry in high school!"

The National You Be The Chemist Challenge (National Challenge) competition is part of a three-day science celebration. Thirty State Challenge Champions from across the nation will travel to Philadelphia to test their knowledge of chemistry concepts, chemical safety awareness, the scientific method, and much more.

All National Challenge participants will receive a variety of prizes such as Thames & Kosmos chemistry sets, gift certificates to the Discovery Channel Store, plaques, You Be The Chemist Challenge T-shirts, bags, and other fun giveaways! The top four placing participants will receive trophies and scholarships for future educational use!

In celebration of the students’ hard work and success, CEF will hold a National Challenge Celebration Dinner for participants, family members, educators, sponsors, and industry members following the competition. The dinner will take place at the National Constitution Center, located in the heart of historic Philadelphia. The dinner will include an award ceremony for the participants and a live chemistry show. The event provides participants the opportunity to interact with the business leaders, chemical industry members, chemists, and educators in attendance.

Additionally, as part of the three-day event, each National Challenge participant and a chaperone will be treated to various activities in historic Philadelphia, such as a welcome dinner at the Academy of Natural Sciences and an afternoon of exploration at the interactive science museum, The Franklin Institute!
