It is important to lead by example!
To avoid using copyright images when creating activities, visit these free-to-use images websites listed below.
If you ask your students to do a project where they need to find images, teach them about copyright, it’s not because a picture or a text is posted online that it belongs to everybody. You can even choose a few of the websites suggested here and teach them how to use them.
In a nutshell…
Copyright means ownership. Without permission, no one can reproduce, distrubute copies, display the photograph or the image publicly.
Creative Commons is a license that allows you to reproduce a photograph or an image. The author/creator still owns the copyright but allows other people to use it for free. Be careful, there are six types of Creative Commons license. Sometimes, attribution is required (e.g.: name of the author). Sometimes, the image can be used but it cannot be changed it in any way (e.g. the background cannot be removed or it cannot be cropped it).
Public Domain means that the piece of work is not protected by copyright law. It can be used without permission.
