Just like many other web based tools, Knowmia can be embedded within Sophia tutorials using the HTML embed code.
Scroll over the insert tab and click on "html"
Next, copy the html code from the lesson site.
Finally, paste the code into Sophia.
Once this is done, save the changes and your lesson should appear in the tutorial. It will play the same as on Knowmia. You can add a quiz or Google form to check for understanding within a new section of the tutorial.
