Obesity
The most basic definition of overweight and obesity is having too much body fat-so much so that it “presents a risk to health.” A reliable way to determine whether a person has too much body fat is to calculate the ratio of their weight to theirs height squared. This ratio, called thebody mass index (BMI), accounts for the fact that taller people have more tissue than shorter people, and so they tend to weigh more.

Learning Outcomes and Objectives:

1)Students will be able to create program to calculate BMI and the categories
2)Students will learn to use formula the BMI scale.
3)Students will evaluate their peers’ work. /

  • Scales
  • High Measuring Instrument
Technology Required:
PC with internet access
Subjects covered:
Mathematics, Science, Health Education,ICT
Age Range:
14-18

5 days
/ Process

Lesson 1:

Teacher prep: in this lesson students will learn to how to calculate the BMI and categories, evaluate the information they find on the internet, create the formula the BMI and to evaluate their peers’ work by commenting on it.

Ask students to create formula the BMI and categories and build the program.

Before the lesson students collect the input, process, and output for the build program BMI. Students should refer the website to identify the BMI scale.

Students are required to choose the appropriate programming language for problem solving

Essential question: Why students to choose the appropriate programming language for problem solving?

  1. Organize the class into small groups of 4 students.
  2. Students discuss the importance of showing program to calculate the BMI and give feedback to the class.
  3. Ask students to decide the BMI categories for different ways it can be done

Lesson 2

Teacher prep: in this lesson students will learn to write the pseudo code and flow chart tocalculate the BMI and categories, to evaluate their peers’ work by commenting on it.

Ask students to write pseudo code and flow chart.

  • Students work in pairs.
  • Students know the input, process and output the program.

Lesson 3:

Teacher prep: in this lesson students will learn coding in programming language to calculate the BMI and categories,

Ask students to data type for input, process and output

  1. Organize the class into small groups of 4 students.
  2. Students discuss the program convert pseudo code to programming language
  3. Ask students to key in programming language into the computer.

/ Process

Lesson 4:

Teacher prep: in this lesson students will learn thetesting and debugging to find any errorin the programming

  • Students work in pairs.
  • Studentsused the programming software such as visual basic to check any error in the programming.

Lesson 5:

Teacher prep: in this lesson students will learn thedocumentation the programming after testing and debugging successfully.

  • Students work in pairs.
  • Studentswrite the program requirements
  • Student write “how to manage the program Calculate BMI and categories.”(Guide User)
  • Student write example for data type input and output.
