Project #29715 - The acid rain problem - report

Description of Assessment

 

 

 

Purpose

This task allows you to:

·                      select, acknowledge, and critically evaluate scientific evidence from different sources

·                      write a report in which you

Ø demonstrate a knowledge and understanding of scientific concepts relevant to the issue of acid rain.

Ø analyse and explain different perspectives

Ø present a personal view about the issue, based on the evidence you have obtained

Ø use appropriate scientific terms and conventions.

 

 

 

 

Background

 

 

 

Water is essential for life on Earth and its quality is, therefore, of great importance.  Clean rain is naturally slightly acidic but when the pH of rain falls below 5.6, we call it acid rain.  Emissions of the two air pollutants, nitrogen oxides (NOx) and sulphur dioxide (SO2) are the main reasons for acid rain formation.  Emissions of these pollutants are decreasing in Europe and North America but are still increasing in Asia and Australasia.

 

 

 

 

 

Tasks

 

In this assignment you will research issues regarding acid rain

 

First, it is important to understand what acid rain is and the chemistry behind its formation. Next, to consider the potential impact of acid rain on the natural and manmade environment. Lastly you must decide on the scope and severity of the Acid Rain Problem.

 

 

 

You will complete 3 sections of work (sections A, B and C). For each section you will produce a different piece of work:

 

 

 

SECTION A:    a poster or webpage outlining the chemistry of acid rain formation.

 

 

 

SECTION B:    a critical thinking activity (300 words) examining the impact of acid rain on the environment.

 

 

 

SECTION C:    a report (750 words or multimodal equivalent) that looks at the range of views that various people have regarding the scope and severity of the Acid Rain Problem.
