WATER TO DRINK MINERAL OR TAP WATER ? THIS IS THE DILEMMA

ABSTRACTIs it really necessary to drink bottled water? Isn’t it cheaper and environmentally eco-friendly the choice to drink home tap water? Is the water of our towns good for our health?


ABSTRACT

Students must analyze the two kinds of water, considering its qualitative and organoleptic aspects, the costs for the environment and for our wallets.


SUMMARY TABLEMaths Content

Calculations and percentages, reading tables, construction of tables and graphs, comparisons of data, equivalence of measures of capacity.


Science ContentWater cycle, sources and surface water, minerals in water, solutions, distilled water, hardness of water, disinfection, air pollution, waste problem.

SUMMARY TABLE

AGE OF STUDENTS : 12-14 years

TOTAL NUMBER OF LESSONS : 7

KEY COMPETENCES

Maths competence and base competences in science and technology, digital competences, learning to learn, social and civic competences, sense of initiative and entrepreneurship.


TEACHING UNIT OVERVIEW

THE SITUATION

Drinking mineral water is increasing. This leads to the bottling of spring water in places distant several kilometers from the place where water is sold.


In addition to this bottles are made of plastic. The transport on wheels produces greenhouse gases and many tons of plastic end up in landfills. On the contrary tap water to be drinking needs to be disinfected through chlorination. But it is cheaper, ecological and it can be delivered at home.


GUIDING QUESTIONS

Can water eventually ends? The transport of mineral helps maintain water quality at

the source? What minerals contain water? What is the environmental cost of road transport bottled water? What is the average cost for families? Is the chlorine present in drinking tap water bad for our health? How hard is tap water?

Which water to drink?


FINAL PRODUCTA short description of the pros and cons of mineral water and tap water. Suggestions and assumptions to overcome some inconveniences. Reflections on the characteristics of the choices: local and use variables.


STEP ACTIVITY1 EXPLORATION Welcome. Presentation of the problem. Brainstorming. Survey of the prejudices connected to the

problem. Building of the main question to which students must give an answer. Map of expectations. Training contract.

2 PLANNING SURVEYDiscussion about how to go on with the research. Definitions of guide questions. What should I do? What it is useful to know, creation of cooperative groups of pupils and distribution of tasks and roles.

3-4-5 IMPLEMENTATION OF SURVEY Working groups. Targeted research of materials, data, information.

6 EXPERIMENT Laboratory experiment on the characteristics of water

7 SHARING DISCOVERIES Written record of single results. Explanation of results.

8 SUMMARY WORK Conclusion. Preparation of the final product.
