Lesson 2

Personal Analysis

Instructional Objective

In this lesson, students evaluate their past eating practices by completing internet quizzes for Body Mass Index and Rate Your Diet and/or Rate Your Restaurant Diet.

Time Required

A minimum of one fifty-minute class period for completing the quizzes selected and printing the results for their portfolio.


You may assign points for this assignment which meet your needs. As a part of the nutrition portfolio, I assign 20 points for this activity.


Connecting Prior Knowledge/Experience/Learning

This lesson begins with the teacher asking students to think about their own body. What are some opinions about size and shape? At the junior high level, I do not ask for oral response to this question. Teacher explains the quizzes students will be completing will help them have a more accurate assessment of their own body shape/size.

Guided Practice

Teacher demonstrates, on a sample student, how to complete the quizzes on the computer/overhead or LCD. If students are not certain of their weight, I usually have a scale on hand. Care must be taken that students have privacy when they weigh themselves, junior high students are easily embarrassed.

Individual Practice/Homework

Students complete their BMI and Rate your Diet and/or Rate your Restaurant Diet quizzes. Results should be printed as a part of their portfolio.


There are numerous quizzes relating to caloric intake, size, etc. which may be completed and added to their portfolio for extra credit points.


Advance Preparation/Prerequisite Knowledge/Skills/Illustrative Materials

This activity works best in a technology laboratory or in a classroom where students all have access to a computer individually. The BMI, Rate Your Diet and Rate Your Restaurant Diet websites should be hot-text items on the monitors. (Possibly in a rotation system where students not on computers may be working on another aspect of the assignment.) Using formulas for the quiz is possible with a good deal of teacher input and explanation.
