Video: Cells

Objectives: 
 * Explain what is meant by the term "tissue engineering."
 * Research tissue engineering, exploring its risks and benefits.
 * Determine a viewpoint on this topic and support the position with research.

 **Materials**
 * //Elements of Biology: The Cell//program
 * Computer with Internet access
 * Paper and pencils

**Bell Ringer:** Write what they know about tissue engineering. If you are unfamiliar with the topic, indicate so on your papers so that it does not affect their grade. Close your notebook until the end of the video.
