Hi,
I teach intermediate level and I don �t know how to teach kids in high school. but here is a thought ....
1- find a video about the movement and let your students understand what you are going to talk about.
2- design question cards about the video and divide your students into groups and let them answer the questions.
3- there is a timeline for this movement, let each group study a specific part and then summarize it.
4- you can tell your students to make an assignment together and discuss it in the next class using different materials.
5- make your students explain what are the effects of this movement on our lives nowadays
as I told you I don �t teach the ages of your student and I don �t know what suits them! I hope I helped a bit
