Draw students' attention to the key ideas of this section using means such as posters and overhead transparencies.

Discuss with students the role of dissection in learning about the human body. For example, students will use a mammalian heart to increase their knowledge of the structure of their own heart.

Assign Mini Activity: Heartbeats and Mini Activity: Word Origins.

Remind students of the important role of models in science.

Activity 2-2: Siphon Pump gives students another opportunity to use a model and provides them with a concrete example of the pumping action of the heart.

Assign Mini Activity: What's Your Cardiac Output Today?

Discuss the importance of a healthy heart in maintaining homeostasis.

Select from Journal Writing prompts, Enrichment Activity 2-1: What Makes the Heart Beat Faster?, Mini Activity: Is Pumping Hard Work?, and the Breathing Projects beginning on TE page 164.

Review the Apply Your Knowledge and the Review Questions responses.

Throughout and at the end of the section refocus students' attention to the key ideas.
