Page history last edited by melamcco@fc.amdsb.ca 2 years, 4 months ago


Overall Expectations

B1. assess the impact of human activities on the sustainability of terrestrial and/or aquatic ecosystems, and evaluate the effectiveness of courses of action intended to remedy or mitigate negative impacts 

C1. assess social, environmental, and economic impacts of the use of common elements and compounds, with reference to their physical and chemical properties 



There are many substances that have been generated in our world that are both useful to human society and had many unintended harmful consequences.  In this assignment your task is not to identify that a substance is bad or good but how it can be managed in a sustainable way to minimize the harmful impacts. 




A) Select one of the following topics.  Your topic must be unique from other students in the class.  



Bitumen from oil sands          

Plastics (Reece & Robyn)



Uranium/nuclear waste (Gabbi)         


You may pick a topic not on the list, just run it by me.  (You can not do nitrogen fertilizer)


B)  Identify some of the key questions related to the topic and conduct research on that topic.  They may include;

What is the chemical make up of the substance?  

Why has this substance been so useful? What properties of the substance make it useful to people in industry or in our daily lives?

Is the substance used sustainably?

How does the chemical get released into the environment leading to exposure to living things?  (air, water, soil)

How does the chemical substance affect people's health and how is this related to its properties?

How does this chemical substance affect the environment?

How does this chemical substance affect organisms in ecosystems?

Describe course of actions that can be taken to minimize the impacts on the environment, human health and ecosystems.


C)  Remember the overall exception and check out the rubric that will be used to evaluate the content of your presentation.  Use it to help you design of your presentation.


D) Conduct a presentation for the class.
