The heart of this module is a set of four class-room lessons that allow students to discover important concepts related to technology and its role in developing our understanding of cellular and molecular biology. To review these concepts in detail, refer to the Conceptual Flow of the Lessons chart.
As you review the lessons, you will find that all contain common major features.
At a Glance offers a convenient summary of the lesson.
In Advance provides instructions for collecting and preparing materials required to complete the activities in the lesson.

identifies when assessment is embedded in the module's structure. An annotation suggests strategies for assessment.
Lesson Organizer provides a brief summary of the lesson. It outlines procedural steps for each activity and includes icons that denote where in each activity masters, transparencies, and the Web site are used. The lesson organizer is intended to be used only after you become familiar with the lesson materials. It can be a handy resource during lesson preparation as well as during classroom instruction.
Masters to be photocopied are found after Lesson 4, at the end of the module.
The timeline below outlines the optimal plan for completing the four lessons in this module. The plan assumes you will teach the activities on consecutive days. If your class requires more time for discussing issues raised in this module or for completing activities, adjust your timeline accordingly.
