Computer Station:

Go to the link provided and complete the questions given – Interactions – View in frames.  It will give you a better understanding of the relationships within ecosystems between orgainsms.  You must put the answers into a word document and post it to the Courseware in our SNC1D group – it will be called – ‘Animal Interactions’… no paper!  If the link does not work go to and go to track # 415139.

SMART board Station:

1.  Go to the following ‘Soils: Characteristics and Impacts’ – ELO1280660 – do the ‘Assignment’ section.  Work through the flash lab to answer the following questions…

  • Why are soils important?
  • What are the impacts humans have on soils?
  • Why are the nutrients, water, pH, and porosity important for plant growth?
  • What is the difference between inorganic and organic fertilizers?
  • Include a data table for all of your results.
  • Construct two graphs to compare the yield and nutrient availability for the organic versus inorganic fertilized fields.
  • What impact will the differences in fertilizer use have on the long-term sustainability of the soils?

2.  Go to the following ‘Disturbing Aquatic Ecosystems’ – ELO1280670 – do the ‘Assignment’ section.  Work through the flash lab to answer the following question…

  • What are the various dangers that threaten the sustainability of aquatic ecosystems?
  • Describe at least three different threats to the ecosystem including the process of eutrophication.
  • Define and describe the importance of the abiotic factors Alyssa investigated on the lake ecosystems.
  • Make conclusions regarding the impact of the abiotic factors on the fish populations using the data you collected to support your answer. Explain the results and the potential impact of the agricultural area.
  • Answer the following: Is eutrophication a global problem? Justify your answer. Research and describe the potential effects of eutrophication (positive and negative) as well as any efforts aimed at reducing the impact.

Physical Lab Station:

Turn to page 44-45 in the textbook.  Complete 1-11 (‘Procedure’, and ‘Analyzing and Interpreting’).

‘Unplugged’ Station: Human Impact

Populations Out of Whack!

Choose one of the following scenarios created by Parks Canada. Each document contains background information regarding the issue as well as data to analyse. You will need to construct a graphical representation of the data. If you are eager, you may also choose to locate other data relating to the impact of a human activity on the populations in an ecosystem, however check with your teacher before proceeding.


  • Develop a hypothesis: What is the impact of pH levels on the loon population.
  • What is the cause of the mercury contamination? Explain using the data from the background information.
  • Is there a connection between the mercury levels and the loons? Explain using the graphs you constructed.


  • Develop a hypothesis: What is the effect of edge habitat on the numbers of moose? How does the number of moose affect road mortality?
  • What is the cause of the increase in moose populations? Explain using the data from the background information.
  • How has the increase affected road collisions? Explain using the graphs you constructed.

Formal Report:

  • Your report is to contain the following three sections:
  • Introduction: Describe the background information for the human activity affecting the populations. State your hypothesis.
  • Data Analysis: Construct a graphical representation for the data analysed.
  • Conclusions: Answer your hypothesis with explanations referring to the graphs and data collected. What is currently being done to improve the situation?
