PDF Files for PrintingUsing the Student Lessons

The heart of this module is the set of six lessons. These lessons are the vehicles that we hope will carry important concepts related to human health and chemicals in the environment to your students. To review the concepts in detail, refer to the chart, Conceptual Flow of the Lessons.

Format of the Lessons

As you scan the lessons, you will find that each contains several major features.

At a Glance gives the teacher a convenient overview of the lesson.

Background Information provides the teacher with the science content that underlies the key concepts of the lessons. The information provided here is not intended to form the basis of lectures to students. Instead, it is designed to enhance the teacher’s understanding of the content so that the teacher can more accurately facilitate class discussions, answer student questions, and provide additional examples.

Notes About the Lessons places each lesson in the context of the concepts presented in the Background Information. It provides a short commentary about the practical application of the concepts to the activities in the lesson.

In Advance provides instructions for collecting and preparing the materials required to complete the activities in the lesson.

Procedure outlines the steps for each activity in the lesson. It provides implementation suggestions and answers to questions. Lessons 1-5 each include an Extension Activity that describes ways to extend or enrich the lesson.

Within the procedures, annotations provide additional commentary.

National Science Education Standards icon

identifies teaching strategies that address specific science content standards as defined by the National Science Education Standards.

Web activity icon

identifies when to use the Web site as part of the teaching strategies. An annotation instructs the teacher how to find the appropriate segment on the Web site. A print-based alternative is provided in each lesson for all Web-based activities in the event that a computer with Internet access is not available.

assessment icon

identifies when assessment is embedded in the module’s structure. An annotation suggests strategies for assessment.

The Masters required to teach the lessons are located in the Teacher’s Guide Masters section.

Timeline for Teaching the Module

There are several ways to complete the six lessons in this module.

The first timeline outlines the optimal plan for completing the six lessons in this module. The plan assumes you will teach the activities on consecutive days. It is important that Activities 3 and 4 from Lesson 2 and Activity 1 from Lesson 3 follow each other on three consecutive days. If your class requires more time for laboratory procedures, discussion of issues raised in this module, or completing activities on the Web site, adjust your timeline accordingly.

The second timeline outlines an abbreviated timeline for completing the lessons in the curriculum supplement by assigning some activities as homework, using the Web site in place of the laboratory experience, and deleting one activity.
