Main Activity Body Mass Index PowerPoint
- 1. BODY MASS INDEX (BMI)
- 2. WHAT IS BMI? BMI is a way of checking that a person is a healthy weight for their height. For your height and weight there will be a healthy range which you should fit into, this range is to account for the fact people have different builds and sizes. Typically the average healthy BMI range for individuals is between 19 and 24.
- 3. HOW TO CALCULATE BMI… To calculate your BMI: Divide your weight in kilograms (kg) by your height in metres (m) Then divide the answer by your height again to get your BMI. - - The formula is as shown below: Mass(kg)/Height(m)² In your spreadsheet you can calculate your BMI applying this formula to your cells…
- 4. YOUR FORMULA… If you enter your weight in (KG) in cell A1 You enter your height in meters in B1 Put this formula in C1... =A1/B1^2 This calculates the BMI. Can you see how this works? Experiment with the formulas and the values to see how the BMI result changes. Make sure your formula is unique to the cells where you have placed your values, not, just a copy of the formula above.
- 5. Have a go yourselves! In groups, you can each measure your height using the tape measures and your weight using the weighing scales. *Make sure you use equipment in the correct unit of measurement, if not your teacher will explain to you how to convert it* Anyone who has not recorded their results share these with a classmate. Now, using your results and the formulas, calculate your BMI!
- 6. EXTENSION When you have managed to calculate your own BMI, calculate the results of the rest of your class’ BMI and keep these all in your spreadsheet. You will have chance to share your results and check them at the end of the lesson. Good luck!
