Human impact on local ecosystems can be negative. Identify a local impact and offer a solution.


Develop a self-contained ecosystem to provide food for a future colony on Mars and demonstrate photosynthesis in action.

Up a creek without a paddle. 

Design a method to efficiently move two pounds of weight across water within a structure no larger than 8.5X11.

Is it hot or is it just me? 

Design a system that either amplifies or decreases the greenhouse effect.  

Citizen science.

Participate in a citizen science project creating a presentation based on your observations and findings. 

Less is more. 

Reduce, reuse, recycle – find an innovative solution for waste.

Mentor Workshops

Want to participate but not sure how to get started? Attend a mentor meetup (open to people who have registered for the Epic STEM Fair). Meet with your STEM mentors to prepare for the fair. Bring your ideas, questions and/or project. Get ready to collaborate and create something great!
