Welcome!

Learn about simple machines and engineering as you design, build and test a Rube Goldberg Machine!  4-Hers living in these North Florida counties can participate in the STEM Challenge at the North Florida Fair this fall during 4-H Day at the Fair, Saturday, November 11, 2023.  After the contest, enjoy the exhibits and midway. 

This site contains resources to help your team prepare for the contest. If you are a parent, volunteer, or 4-H employee, please check out the getting started page first. Questions, contact Heather Kent at hckent@ufl.edu
