Help your students take more ownership of their learning through questioning. You will provide them with a hook (some media related to your upcoming content), and students will brainstorm as many questions as they can for several minutes. From there, they'll select their top questions to share with a partner. The partner group will select 2 top questions to share with the class, and then the class will select a couple top questions to look at over the course of the unit. Teachers will withhold judgement and refuse to define what a "good" question is, allowing students to set mastery criteria on their own.
For an extension activity, students will brainstorm what next steps they would need to take in order to answer their higher order questions, leading them into the planning and further ownership of your upcoming unit!
I use this in science, but it can most certainly be used in any subject.
