Technology with Purpose logo is a national non-profit with a mission to empower  "all students to use technology as a force for good."   They offer many amazing resources for CS and STEM educators, including an online learning platform, project database and a monthly microproject competition.  The projects are incredibly well done, creative, easy to follow, and perfect for middle to high school students. I have used a number of the unplugged and online activities in my middle school classroom and they work well in an online or face to face environment. My students' favorites include Javascript Takeover and Design a Mobile App.

Membership to their 16 STEM and CS courses is currently free and open to all educators for the remainder of this school year.  Courses include Electronics & Circuitry, Coding, Design with a Purpose, and Impact Game Design.  I encourage you to check it out!
