All OpenSciEd units are designed as open educational resources that are licensed as CC-BY-4.0. This license allows educators to use, modify, and reuse all of our resources to meet their students’ needs. This license does require appropriate attribution, which means you must give credit to the author, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests that OpenSciEd endorses you or your use.

We encourage educators to share broadly and openly any changes and innovations they make to these resources so others can reflect on and take advantage of their best thinking.
