The CIE/USA-DFW (cie-dfw.org) and the Share &Grow Association (www.sharegrow.org) proudly host the 2021 Student Engineering & Creativity Convention (SECC).

Vibrant experiences of SECC workshops and competition, which enable students from K-12 to expand their knowledge, test, and showcase their innovative ideas and designs.



The SECC competition is an exciting learning opportunity for students to take on real-world problems through hands-on projects.

Two types of competitions are provided:

Division A: Marble machine (K-5th grade)

Division B: Build your own plotter Machine (6th – 12th grade)


Two workshops and lectures will be provided with renowned experts in the engineering fields and experienced students to demo the projects (including competition projects) and to inspire participants with new ideas and techniques to solve challenges. 


The annual SECC programs provide a platform for students with similar interests to get to know one another and share ideas, to interact with academic faculties and industry professionals.
