Part of Lesson Plan: **Broken Bolt Extraction Methods Part 2 (updated) by Robert Thayer

Activity Overview / Details

5-10 minutes

Background:

Each day when students enter the classroom, I usually have a warm-up question projected on a video screen, but you could write it on the board. At the beginning of the week, students grab a new blank warm-up work sheet, which I have created for them, which students keep in a folder in their back packs. Students complete all the warm-ups for the week on that sheet and turn in their sheet to me at the end of the week for grade points.

Also, under the daily warm-up question, I have an outline of our activities for that day.

Activity:

As students enter, I wait for them to take their seats and ask them to take out their warm-up work sheets. Then I call their attention to two videos demonstrating broken bolt extraction. Before I run the videos, I tell students they will be required compare the two videos by writing down two similarities and two differences between the techniques used. I show both videos, and give the students a couple of minutes to write down similarities and differences.

After a few minutes, I call on students to share their answers with the class.  As students give their answers, I repeat their answers out loud. I will also call on non-volunteers. Then, I take about five minutes to comment on the video content. I will explain what I like and dislike about the techniques used, and why.
