These days, students are exposed to media information about leading a healthy lifestyle by eating right and exercising, yet they may not be aware of the reasons why leading such a lifestyle is important. Investigating Digestion and Motion explores digestive processes and organs, nutrients and vitamins, and the musculoskeletal system, all key elements of a healthy body.
STC-Secondary™ is a 16-unit, inquiry-centered middle school science curriculum developed by the National Science Resources Center, an organization of the Smithsonian Institution. Each STC-Secondary™ unit provides opportunities for students to experience scientific phenomena firsthand. A comprehensive, research-based curriculum, STC-Secondary™ is aligned with the National Science Education Standards.
1-Class Unit Kit comes with a Teacher's Edition, a Teacher's Tools CD-ROM (item #976807), 16 reusable hardbound Student Guides (item #976803), and the materials needed for a teacher to teach up to 32 students per day. 1-Class Refurbishment Set (item #976804) replenishes kit consumables.
Investigating Digestion and Motion focuses on the digestive system, and in the introductory activity, students simulate peristalsis. Students then explore the digestive processes that occur in the mouth, stomach, and intestines as they read about balanced meals, nutrients, and enzymes. During the sequence of lessons in the Investigating Digestion and Motion unit, students look at both physical digestion—chewing and peristalsis—and the chemical digestion of carbohydrates, proteins, and fats. These chemical processes are further explored as students conduct their own experiments to search for the presence of sugar and starch, scrutinize for evidence of diffusion, observe the effects of pepsin and gastric juice, and build models.
Each lesson in this module builds on skills and concepts presented in previous lessons. As students progress through the module, they take greater responsibility for their own learning, eventually planning and conducting their own procedures, devising their own data tables, and analyzing the results they obtain. Unit begins with an assessment of students’ current understanding of the topic and ends with performance-based and written assessments.
