Khan Academy

In this post, I'll tell you about a really cool new site I found: Khan Academy.

Khan Academy is basically a bunch of free tutorials for school subjects like mathematics, history, science, and just about anything else. And not only that, but they also have a special practice page that offers exercises, and when you complete enough of them you get points.

And here's one of my favorite things about it: they have a special section just for computer science, so I can write programs (mostly video games), and everybody else can see and play them. So far I've only written one program, but it's pretty good for my first (even though it's not finished yet). But one of the coolest things about that programming feature is that you can embed the program on a web page:

Super Ball

Another nice thing is the badges you get for accomplishing certain things. There are 6 types: meteorite, moon, earth, sun, black hole, and challenge. The easiest to get are the meteorites, and the hardest are the black holes (you don't even know how to get the black holes!). The challenge badges are just extra stuff. You can display up to 5 of your badges on your profile page for everybody else to see.

So check it all out - go to! If you ever forget the link, just check my Links page.


  1. I was wondering what embed code you used to embed your program into your blog? I tried just copying the embed code from my program on Khan Academy but I don't think the new code is working for blogs. Thanks!

    1. I post KA programs on my blogs all the time.

      just click the "share" button and under all the social icons is some code for embedding, click highlight it, copy it and paste it in the HTML in your blog-post.

  2. I wrote a Khan Academy program that will generate some HTML to use for embedding here:
