Once you create a YouTube playlist, it will ask you to title it. You can make it completely public (which would be searchable), unlisted (people need the link to see it), or private (just for you). You can continue to add videos to it (including any edu video---not just Amoeba Sisters videos) and reorder the videos in the playlist.
On many websites and platforms, playlists can even be embedded where they will look nice such as this one below! Here are instructions for how to embed a YouTube playlist (a little different than embedding an individual YouTube video).
Don't forget to encourage students to create their own study YouTube playlists for content that is challenging to them. Want some more YouTube tips? See our other post.
