This challenge, conducted by the Chemical Education Foundation (CEF), is its flagship program exclusively for middle school students. For this challenge, students will first participate in regional challenges to qualify for the National Challenge, and present their video and research work in response to the theme of the challenge – varies year on year. Typically, you are expected to propose founding a start-up company to investigate sustainability questions and community-based solutions.

Participating in the challenge will help students develop essential skills such as critical thinking, effective communication, entrepreneurship, and problem-solving, which could be useful for college applications and in their professional careers. You can participate either via the in-person or virtual option. Participants in both options will need to attend the National Challenge in-person in Houston, if selected. The first stage is when students participate in teams of 3-4 and attempt a 40-exam question administered by your school.

This is a qualifier for the regional challenge, in which students will have to answer 40 questions individually again. Regional participants then need to submit a 5-7 minute video which will be the basis of their selection for the National Challenge. 

Location: Varies year on year. 

Cost: $35 per student. 

Application Deadline: Your enrollment depends on how well you compete at your entry-level science Bee. 

Dates: Typically, October to December, depending on which level you compete at.

Eligibility: Students in grade 8 and below.


The National Science Bee is a quiz competition for students, to test their knowledge across different concepts in science at each grade-appropriate level. Students, participating individually, must first qualify by taking the free Online Regional Qualifying Exam (ORQE) which is available in the fall.
