Is your objective something like, "the student recognizes that science is a progressive endeavor that evaluates and extends what is already accepted"? Are you a teacher who endeavors to help the school wide initiative to encourage reading? If so, this opening activity will bring a relevant science topic into your classroom, and it involves reading.
Each student receives a handout. While I take attendance, each student reads the short Popular Science article, highlights and follows directions. Those who forgot their highlighter, underline the required information. Ten minutes is generally all students need to complete the activity. Together, the class and teacher go over vocabulary and answers. To create a vocabulary bulletin board choose 2 or 3 key words to add to the word wall. To extend the bellwork into a full classroom session create a discussion on TMI in athletics by adding a few clips from the 2016 movie staring Will Smith, "Concussion" or the 2012 documentary "Head Games". I'll be creating a viewing guide on both shortly. Let me know if you want notification when this is complete.
If you are using my bellwork form, each student enters "Reading Activity on TBI/Stem Cell Research" in the daily box, and staples his/her work to the bellwork sheet for collection on Friday.
Should you use this as an observation, I have included is Ticket Out the Door to make your observation and lesson plan complete. (Good luck!)
