Do you still have questions about how to participate in LEAF?  Let us answer them for you!  Here's a list of our most asked questions:


What is the LEAF STEM Challenge?
The LEAF STEM challenge is an engineering design challenge for middle and high school students.  The basic challenge is for students to build an electric aircraft that will carry the most amount of cargo.  You can learn more about the LEAF STEM Challenge here and read the competition rules here.

Who can participate?
We welcome the participation of any students- formal or informal- in middle school (grades 6-8) and high school (grades 9-12).  Younger students may still participate, but are ineligible for awards.

How do I get started?
Check out our Resources page!  It contains a curriculum overview as well as materials to help you get started.  You can also attend our annual summer coaches workshop.

How much money do I need for this project?
The LEAF STEM Challenge is a low-cost way to teach aerospace and engineering design.  Each airplane costs around $12.  The power pole and power supply can vary depending on if you choose to purchase one (estimated $350) or use the instructions on our Resource page to go the DIY route (estimated $100).

Where can I find funding for this project?
Even though this project is low-cost, funding may be an issue and we encourage you to check with local organizations for available funding.  Here are a few grants that we know of that might help:
Air Force Association
American Institute of Aeronautics and Astronautics
Pacific Northwest AIAA
Puget Sound Engineering Council
Harbor Freight Tools for Schools

How can I learn more about the LEAF STEM Challenge?
We encourage you to attend our annual summer workshop where you can learn more about the project and design, build and fly your own electric aircraft!  If you've missed it or still have questions, please let us know.

Can I register teams with a Purchase Order?
Of course!  We are happy accept purchase orders for schools and organizations wanting to register 5 or more teams.  Click here for more information.

How can I register more than one team?
Our registration system through Constant Contact will only allow an email address to be used once, so in order to register more than one team, you'll need more than one email address.  For the majority of us who don't have 10 emails, we have a workaround.


If you have a question that hasn't been answered, please contact us and we'll be happy to help!
