Food, Energy and Body Weight

This analysis and discussion activity helps students to understand the relationships between food, energy, cellular respiration, and changes in body weight. Analysis of a representative scenario helps students to understand how challenging it is to prevent weight gain by exercising to offset what seems to be a relatively modest lunch.

In an optional research project, each student asks an additional question and prepares a report based on recommended reliable internet sources.

The Student Handout is available in the first two attached files and as a Google doc designed for use in distance learning and online instruction. The Teacher Notes, available in the last two attached files, provide instructional suggestions and background information and explain how this activity is aligned with the Next Generation Science Standards.
