PDF Files for PrintingUsing the Student Lessons

The heart of this module is the set of six lessons that follows. These lessons are the vehicles that we hope will carry important concepts related to oral health 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 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.

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

Procedure outlines the steps in each activity in the lesson. It provides implementation suggestions and answers to questions. Wrap-up offers suggestions for using the Mouth Journals as opportunities for assessment. Lesson 2 has Extension Activities that enrich the students’ experience with the module through additional games.

Within the procedures, annotations provide additional commentary.

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

Web activity iconidentifies 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. Information about using the Web site can be found in Using the Web site. A print-based alternative is provided in each lesson for all Web-based activities in case a computer with Internet access is not available.

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

There are three Take-home Activities included in the module as part of Lessons 2, 3, and 5. These activities are designed to engage children and their parents in oral health concepts at home. The handouts for the take-home activities are located in the Masters section. A certificate at the end of each handout provides evidence for the teacher of parent-child interaction.

“The most gratifying part for me has been the POSITIVE feedback from parents as well as from the kids...we have just finished conferences and almost every parent commented that their child has come home and told them daily what we are doing and learning. Some families still have the egg experiment from one of the take-home activities going on their own!”
—Field-test Teacher

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

Timeline for Teaching the Module

The Open Wide and Trek Inside module is designed to be taught every day for a period of approximately three weeks. Field-test teachers found that if they scheduled science lessons every day while they were teaching the module, students remained engaged and their understanding of the concepts that link the activities together steadily grew.

Wrap-up

The preceding timeline outlines the optimal plan for completing the six lessons in this module. The plan assumes you will teach the activities on consecutive days, spending approximately 20 to 30 minutes on science activities each day. If your class requires more time for laboratory procedures, discussion of ideas raised in this module, or completing activities on the Web site, adjust your timeline accordingly.

The following is a complete list of supplies needed for this module. Quantities are based on a class of 30 students.
