Khan Academy allows you to learn almost anything for free.
Our iPad app is the best way to view Khan Academy’s complete library of over 2,600 videos.
We cover a massive number of topics, including K-12 math, science topics such as biology, chemistry, and physics, and even the humanities with playlists on finance and history.
Spend an afternoon brushing up on Statistics. Discover how the Krebs cycle works. Learn about the fundamentals of Computer Science. Prepare for that upcoming SAT. Or, if you’re feeling particularly adventurous, learn how fire stick farming changed the landscape of Australia.
Included in our iPad app:
Downloadable videos: take individual videos or entire playlists to watch offline at your own pace
Subtitles: follow along, skip ahead, or go back by navigating through subtitles
Track your progress: Log in with your Khan Academy user account to get credit for watching videos, and see your achievements
Exercises coming soon!
It doesn’t matter if you are a student, teacher, home-schooler, principal, adult returning to the classroom after 20 years, or a friendly alien just trying to get a leg up in earthly biology. The Khan Academy’s materials and resources are available to you completely free of charge.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
