FINAL TASK
The environmental impact of mineral extraction
The final task of this unit aims to raise awareness of the importance of the sustainable management of mineral resources. Nowadays, we
live in a world of consumers, and we rarely ask ourselves where things we use come from, or the human costs and environmental needs.
When new objects come out in the market, we do not appreciate the ones we have and often refuse to use them even if they still work
properly. We do not even think about what to do with the objects we do not want anymore and how they can pollute the environment if
we do not throw them away properly.
At the beginning of the unit, the final task and its objectives, in this case, were introduced with a
slideshow presentation
.
On page 47 we introduce the final task with some questions to motivate the curiosity of students.
On page 65 we explain how to do the research and how to prepare the slides.
❚
In the section
Research
there are four questions to guide students during the research.
❚
In the section
Tasks
there is a reminder about what they need to do.
❚
The
Procedure
section indicates the steps students must follow during the research, how they organise the information before making
the slides, and the importance of reviewing all the information to make sure they are doing things correctly.
❚
The
Self-assessment
at the end of the page will make them think about their work and the development of the final task.
Unfortunately, there is no time to present all the slideshows. Choose one, or reduce the timing presentation and give the chance to another
group.
The
learning outcome
that will be reinforced by doing this task, in the section 2, is the 10.1. Recognise the importance of minerals and
rocks for humans and of managing these resources in a sustainable way.
The learning outcomes from sections 1 and 7 will be also developed.
An example of how to assess the final task is shown here:
0 = not handed in
1 = very basic
2 = well done
3 = excellent
0 1 2 3
