Through this rotation we will be able to:
- Develop an appreciation of how human societies depend on sustainable ecosystems but cause habitat change, overexploitation, pollution, introduce invasive species, and climate change
- Give explanation and examples of the different interactions that occur between animals
- Understand the intricacies of human impact on soils and aquatic ecosystems due to agriculture and other activities.
Activity One: Interactions Videos
Please watch and learn… take a few jot notes when you need to for the first two videos.
Shark and Turtle
How does the turtle protect itself?
What relationship is held between the tiger shark and the loggerhead turtle?
Unlikely Travel Companions
List three ways in which being near a shark might be beneficial to a fish.
What is one way that a shark might benefit from a fish (other than as prey)?
Classify each shark-fish relationship shown in this video segment as commensalism, mutualism or parasitism.
Collapse of the Sharks
Why are shark populations in danger of collapse?
How has the relationship between sharks and humans changed over time?
What might happen if the shark fin trade continues unchecked?
Sharks in Our Future
Describe the type of tourism seen in this clip.
What benefit do these businesses provide to: sharks? To local populations? To tourists?
How might these businesses help prevent the collapse of shark populations?
Activity Two: Can We Feed the Growing Population?
Please go to the following link – http://bit.ly/1d-soil
Only certain activities and pages need to be visited to complete this activity. Please pay attention to this!
Activity 2: Preserving Soils
‘Growing food needs soil’
- How much land makes up farmland across the world?
- Looking at Canada – do we have more farmland then other countries? Explain
‘What is Soil?’
- draw out and label the diagram!
- Plants absorb nutrients through their roots. Describe why plants’ roots grow extensively in the topsoil.
Plants’ roots grow extensively in the topsoil because…
- Explain why the slope you chose increases the erosion rate.
- Plants need nutrients to grow. Explain how erosion can affect plant growth.
‘Putting Down Roots’
- How does grass affect the amount of soil eroded from zone 1?
Activity 4: Soil Quality
‘What makes for good quality soil?’
- What is soil health?
‘Improving Soil Health’
- Explain why the tillage method you chose preserves soil quality.
‘What makes higher quality soil?’
- Explain why the tillage strategy you chose leaves more roots in the soil.
- Explain why the tillage strategy you chose results in less erosion.
‘What nutrients do plants need?’
- Which crop would be good to plant after harvesting a wheat crop?
Activity Three: Predation Simulation
Lynx are members of the cat family that live by preying on snowshoe hares. In this activity, you will simulate the predator-prey interactions between these two animals using a model in which a desk represents a forest and cardboard and paper squares represent the lynx and hares in that forest.
Turn to page 44-45 in the textbook. Complete 1-11 (‘Procedure’, and ‘Analyzing and Interpreting’).
Activity Four: Deforestation and Desertification
Read through the article provided – Deforestation and Desertification.
Be mindful as you read that you do not need to make notes but you need to pay attention to details that will support you to complete the assignment.
- Create 5 Questions for this article. Make the questions in-depth and more then the obvious (where you can) – use the Q-chart for making questions (stay out of data gathering – knowledge/factual quadrant). You must provide the answer to each question (point form is fine if you are providing details!).
- Knowing about the Holocaust in the Second World War, explain why the term “Forest Holocaust” has been used. **If you do not know what the Holocaust is please look it up before answering.
- Does this article leave you with a feeling of “hope” about our future? Explain your answer and use points to back it up. It should be a well constructed paragraph (5-10 sentences).
Activity Five: Human Impact
Please read 52 to 68
If you do the ‘Learning Checkpoint’ questions it will focus your note taking!!
Summary of what you will learn in this reading:
- All human societies depend on sustainable ecosystems characterized by maximum biodiversity.
- Managing the world’s ecosystems means achieving sustainable use, preventing sudden irreversible changes to ecosystems, and addressing the impact of poverty on society and sustainability.
- Habitat change, overexploitation, pollution, invasive species, and climate change are the main factors influencing loss of biodiversity.
Activity Six: Feeding the People
Please grab the reading and question set – Feeding the People.
Complete all questions. Remember that some questions may not be directly answered in the reading but questions you need to THINK about :o)
