Instructional Ideas

• Pause video at 8:17 and allow scholars to, either independently or in pairs, work through the example problem

Classroom Considerations

• Teacher needs a computer, access to the Internet, and a way to project the video to use the resource
• The video repeats concepts taught in the fourth video in the series
• Video 13 in a series of 31

Pros

• Gives students a problem to work and walks them through the answer
• At the end, the narrator says that today, we just sequence the DNA, but if we compare our sequence to the work of Morgan and Sturtevant, it matches up perfectly

Cons

• None
