Our Interdependent World (Biodiversity and Interdependency)

Thinking about learning

The Learning Log

After each lesson complete a learning log at the back of your jotter. A learning log should include at least two of the following headings, especially 5): The headings should start ...
1) I really enjoyed ....
2) I want to find out more about ....
3) I was unsure about ... .
4) I was surprised by ...
5) I learned that ...

Our Interdependent World in context (i)

CFE Outcome: I can explain some of the processes which contribute to climate change and discuss the possible
impact of atmospheric change on the survival of living things SCN 3-05B
Homework...Not as Green as we thought

In 2015 a famous car company was involved in an emissions scandal. Find out about this scandal and write a short passage on it. A good attempt will mention what emissions testing is, the company involved, why it was important the company was exposed and why you think you were asked to research this news in 'Our Interdependent World' topic.

Find out more about climate change and answer the following questions. You can work in pairs and can present these answers in any way you choose; poster, slideshow, or booklet. You can also present your work to the class.

1. What is climate change?
2. What causes climate change? Refer to one of the lessons you did in class.
3. In what way does climate change affect living things? Give one or two examples.

The short YouTube videos will help you. There may be other videos you would like to watch and share with the class.

' i) What do you think the message of the 'Climate animation' video is?
ii) Watch the second video 'Climate science in a nutshell' and describe the problems facing the pika.

Our Interdependent World in context (ii)

This assignment will enable you to demonstrate the following outcome:
I have collaborated on investigations into the process of photosynthesis and I can demonstrate my understanding of why plants are vital to sustaining life on Earth. SCN 3-02a
In class we carried out two investigations on green plants
The investigations were:
i) Leaves deprived of sunlight and the presence of starch in plants.
ii) Leaves deprived of carbon dioxide and the presence of starch in plants
Part A ..Write a full report on one of these investigations. In your evaluation write down who you worked with and the role you played in planning and carrying out the experiment. Click here for the photosynthesis lesson we carried out in class.

Part B ..Using a poster, powerpoint or otherwise explain what photosynthesis is and why it is a vital reaction in sustaining life on Earth. Click here for a short video on photosynthesis to help with your answer. A good answer will achieve a Secure grade.

Part C: Note: Make sure your answer to Part B, however you choose to present it, covers the following points. If you find Part B too difficult then you can simply do Part C instead. Good answers will achieve a Consolidating grade.

The answers to the questions are either daytime or night time. Remember to answer in sentences.

1. When do plants absorb more carbon dioxide than they release?

2. When do plants absorb more oxygen than they release?

3. When do plants release more carbon dioxide than they absorb?

4. When do plants release more carbon dioxide than they absorb?

5. Find out what Respiration means.

In your own words, explain why life on Earth would be impossible without plants.


Part 1 A recent radio broadcast in Australia
Recently an Australian politician caused quite a stir when he admitted he clubbed cane toads to death using cricket bats and golf clubs and urged others to do the same.

Find out about the history of the cane toad in Australia, why they are seen as pests and the measures people are taking to eradicate them. A good answer will expain what an 'invasive species' is and what the cane toad debacle teaches us about tampering with foodwebs.

Part 2 If you find part 1 too difficult then attempt the following.

Draw a simple food chain with three living things.

Use the following information to construct a foodweb

Worms and snails eat green plants.
Sparrows eat worms and snails
Frogs eat snails
Foxes eat frogs
Owls eat sparrows and frogs.
What is the producer in the above foodweb?
Name a consumer in the above foodweb?
What is moving in the direction of the arrow?
What will the problems be if the snails suffered a disease and their numbers drastically reduced.
