YouTube videos must be approved by usd403.org teacher or administrator before students can view them.
To approve a video, go to the video's page and look for a blue bar directly below the video.
The blue bar will either say "Video not approved for.." or "Video approved.."
If it says not approved, look to the right on the same blue bar and you'll see an Approve button to click.
Click this button, the text will change to reflect it is approved, and you're good to go.
