GLOBE PROGRAM

5. Human Health (13-14 yrs)

Introduction

  • Resources/Materials Needed: Local Health Report

  • Target Age Group: 13-14 years

  • Curriculum Areas: PSHE, Science, Geography, ICT, Art

  • Method Used: Role Playing, Investigation/Research, Report Writing

Health and the environment are closely linked. As pollution levels rise and spread more widely across our world, we see the effects on the health of not just Mother Earth but ourselves as well.

In the 3. Measuring Air and Water Pollution we already mentioned water and air pollution as main cause of child mortality. Other examples of health problems are skin cancer from exposure to ultraviolet light, impaired child development from lead in the atmosphere, more cases of asthma in young people, and more typhoid and cholera after floods. All these are on the rise. This activity encourages students to investigate the environmental problems that could lead to health concerns in their community.

Process

Imagine you (the teacher) are an Environmental Health Consultant who has been awarded a contract to assess the health of the community. A final report will have to be submitted by a deadline to the Local Health Authority. Their costs have been increasing as more and more people in the local  community are suffering ill health. The Health Authority has an idea that it is connected to the obvious deterioration in the local environment. They want to identify causes and receive suggestions for action to improve the state of the community environment, thus reducing illness and therefore costs.

  Prepare a questionnaire based on a local health report.

  Introduce yourself to the class as an Environmental Health Consultant. Inform the class they have been selected to help the Local Health Authority determine the sources of health problems in their community.

  Split the group up into separate groups, or “Agency Teams”, of 5-6 students, each producing a separate report.

  Ask the students to answer the questions in the next week: some of the questions can be answered by the students themselves while other answers will come from questioning their peers, families and the general public.

  Explain to the students that the questionnaire aims at researching what the local environmental problems are, where they occur, at what times of year, and what, if any, is their direct link to health issues.

  Collect all the questionnaires and sum up the outcomes on the black board.

  Discuss what kind of environmental problems occur in the local environment.  This can be done through the results of the questionnaire, but can also be done by seeing what issues come up from the students’ discussion in the classroom.

  Ask each group to analyze the results of their own investigation and make a report of their findings for the “Local Health Authority” (teacher).

To Conclude

This Activity allows students to investigate their surroundings and to determine the origin of environmental and health problems that may plague their community.  It provides them with a sense of empowerment, to be able to identify the problems and make a report of their findings.

Outputs:  

A well designed investigation and report.
