In this unit on metabolic reactions, students use a real case study of a middle school student to develop models to explain how the body uses food and how the body’s subsystems work together.
The Vernier Supplement to Unit 7.3 is a complement to the OpenSciEd curriculum and includes data-collection technology enhanced lessons to supplement the existing curriculum.
There are 14 lessons in the full OpenSciEd Unit 7.3
2 lessons are enhanced with Vernier data-collection technology—included in the Vernier Supplement to Metabolic Reactions.
|Lesson 1: What is going on inside M’Kenna’s body that is making her feel the way she does?|
|Lesson 2: Can we see anything inside M’Kenna that looks different?|
|Lesson 3: Why do molecules in the small intestine seem like they are disappearing?|
|Lesson 4: What happens to food molecules as they move through the small intestine and large intestine?|
|Lesson 5: Why do large food molecules, like some complex carbohydrates, seem to disappear in the digestive system?|
|Lesson 6: What happens to the different substances in food as it travels through the digestive system?|
|Lesson 7: What is the function of the digestive system, and how is M’Kenna’s digestive system different?|
|Lesson 8: What does the surface of M’Kenna’s small intestine look like up close compared with a healthy one?|
|Lesson 9: How can a problem in one body system cause problems in other systems?|
|Lesson 10: Why is M’Kenna losing so much weight?|
|Lesson 11: What happens to matter when it is burned?||Go Direct®
CO2 Gas Sensor
|Lesson 12: Does this chemical reaction to burn food happen inside our bodies?||Go Direct®
CO2 Gas Sensor
|Lesson 13: How does a healthy body use food for energy and growth, and how is M’Kenna’s body functioning differently?|
|Lesson 14: Do all animals do chemical reactions to get energy from food like humans?|
