Opportunity X 2021 Engineering Boot Camp

Opportunity X is a 501(c)(3) non-profit organization created and led by a group of high schoolers to share equitable science research opportunities with local middle schools. 


We are hosting a FREE & VIRTUAL five day long engineering boot camp this summer! We'll run through one engineering project during our 2 hours Zoom session each day. We will also post tutorial videos on our YouTube channel in case you have to miss a session. 


The five engineering projects are: Make your own rain stick; Non-round rollers; Epic marble run; 3D printing CAD; and Duplicate your drawings with a machine. For each project, we will explain the engineering principles that make it possible and guide the students through hand-on experiments. Our volunteers have worked really hard this summer to ensure small class sizes and provide engaging interactive activities for all the campers.

We have two program times:

4-7:00 PM EDT  7/28 (Wed) through 8/1 (Sunday) over Zoom

4-7:00 PM PDT  7/28 (Wed) through 8/1 (Sunday) over Zoom

Deadline to RSVP is Saturday, July 17 before 9PM. We will fill up our slots first come, first serve — so sign up soon!
