If you are creating a lesson as a form of a private playlist for your own use in the classroom, you should have the same freedoms as you would when making any projects for in-school educational use. However, if you have made your lesson public, please be aware that items within it may be protected by copyright - just as they would be if you included them in a blog or a lesson plan you would share with your department.
