Instructional Ideas

• Video oversimplifies the concept into genes being either on or off; for advanced classes, go into more detail on the actual continuum
• Break down the word epigenetics into root words to help pupils remember the meaning

Classroom Considerations

• Relies on prior knowledge of mitosis, chromosomes, and genes

Pros

• Provides a high level of detail for those needing a bigger challenge
• Stresses the importance of cell differentiation, even in adults

Cons

• None
