Keeping healthy - diet and exercise KS4
These activities can be used in the delivery of the topic "Diet and Exercise" at KS4. It is envisaged that the lessons would run in the following sequence:
1. What nutrients do we need? What nutrients are in food? How can we have a balanced diet? Use the giant food label to illustrate how pupild can find out nutritional information from food at home.
2. BMI/obesity. With higher sets, give out the article "Fat is not a four letter word" to use as a starter for a discussion on obesity. Pupils could be given the opportunity to find out their own BMIs and to research the different measures for a healthy weight, along with their limitations (using the BMI caculator site). Pupils could also be given the information from "Britain at a glance" and asked to plot their own graphs or to discuss the statistics given. The problems associated with obesity should also be covered at this point.
3. Smoking. The BHF advert could be used as a starter for a lesson on the health problems associated with smoking.
4. Use the "Healthy Chocolate" activity to allow pupils to test their skills of scientific analysis to investigate claims about a new chocolate bar.
5. Use the NHS Choices website to allow pupils to investigate how different people could lead a healthy lifestyle. For example, they could develop a diet and exercise plan for people with different activity levels and needs (e.g. a footballer, an office worke, a pregnant woman, a toddler, a teenager etc.).
Links and Resources
This is a giant food label to be projected onto a whiteboard. If you hover the mouse pointer over different parts of the label, information pops up at the bottom of the screen to explain what each section means. This could be used as an explanation to help pupils understand food labels before they use labels they have collected to compare the nutritional value of different foods.
This article describes the problems relating to people's perceptions of obesity. It could be used as an interesting point of discussion for a more able class.
This link to the BBC website contains information about the calculation of BMI and other measures for working out how healthy a person is, such as body shape and waist:hip ratio. There is also a link to an interactive BMI calculator. This link could be used on a whiteboard to demonstrate the calculation of BMI, or as a homework for students to calculate their own and others' BMIs. The site could also be used to enable students to perform their own research into the effectiveness of different methods for calculating healthy body masses.
There are two documents from 2007 and 2008 produced by the Economic and Social Research Council detailing a number of statistics about the population of the UK. Page 7 contains some interesting data on health in the UK, including obesity rates. Students could be given the data and asked to evaluate the reasons for and consequences of the data.
This video on Youtube is the British Heart Foundation's advertisment from their 2003 "Stop smoking" campaign. It shows the effects of smoking on the arteries.
This Upd8 activity tests enquiry and scientific investigation skills by asking students to evaluate claims made by a manufacturer that its chocolate bars are good for the heart.
The NHS Choices website contains a wealth of information about how to live a healthy lifestyle. Students could use this to research different diets and to formulate diet/exercise plans for people with different lifestyles.
