Systems Module Geography Lessons Lesson 2 Rainforest Ecosystems Aim- Why is the rainforest the most productive ecosystem on Earth?
Come up with a list of adjectives (descriptive words) for a tropical rainforest, on word worksheet
Things to think about…..
What would you smell, see, hear, feel???
ADD LINK OF SOUNDS FROM FOREST
Using the information on the following slide to complete TASK 1 – describing the location of rainforests, the rainfall and temperatures found there ( word )
Where is the Amazon? Amazon Do you know a) which continent the Amazon is on? and b) which hemisphere is it in? Complete your answers in Word
Why does it rain so much in the rainforest?
After millions of years of growth, the vegetation in the rainforest forms four main layers
Soil is poor, so plant roots grow close to surface to utilise the nutrients
Tallest trees have buttress roots to stop them toppling over
Emergent trees Canopy Under Canopy Shrubs Undergrowth 50m 0m Layers of the rainforest liana buttress roots

Images from Malaysian Rainforest August 2004
Nutrient Cycle Twigs and leaves fall to the ground and become ‘litter’ Decomposition (breaking down) of litter by termites, fungi and bacteria Nutrients enter the soil Soil is fertile Dense vegetation
Leaching washes out soil nutrients
Less vegetation Broken Nutrient Cycle Deforestation Fill in the gaps in word worksheet
You have now learnt some background information on Rainforests.
It is now your turn to see how knowledgeable you are!
You will now create a pie chart showing what a Rainforest consists of.
Look at the Pie Chart shown.
You will use a Pie Chart similar to this to show what you think a Rainforest consists of.
You will look back at your chart at the end of your lessons on Rainforests to see if you still agree with your estimates.
You will use the Pie Chart on the previous slide to show your estimations of what a Rainforest consists of.
You will then record your estimations on a worksheet provided for you. Task 4
Simply return to the Pie Chart and 1) Right-hand click on your mouse; 2) Click on ‘Chart Object’; 3) Click on ‘Edit’; 4) Change the percentages in the ‘Datasheet’ showing what percentage of each matter you think a Rainforest consists of.
Now you will do some group work looking more closely at Rainforests, where they are located around the World and why they are so important to the Earth and our Environment.
In groups you will be given a Rainforest to research and investigate.
At the end of your research, you will be asked to write a letter to the Government explaining about your individual Rainforest and why it is so important to help in the conservation of it.
Main Activity Cont. The grid below shows you what information you need to research about your Rainforest. Any effects your Rainforest has on the outside world. Conservation groups linked to your Rainforest . Dangers facing your Rainforest. Why your Rainforest is important. Zones of the Rainforest. (Canopy etc.) Any endangered species living there. People that live there. Any medical remedies grown there. Climate of your Rainforest Type & Location of your Rainforest Animals that live there. Vegetation
Main Activity Cont. Below are the Rainforests that are to be researched (one per group).
All of these web-pages either have information on them, or link you to other web-pages that are packed with information.
Main Activity Cont.
After you have finished researching your individual Rainforest in your groups, you will then each write a letter to the Government campaigning for the conservation of your Rainforest.
You will use the writing frame on Microsoft Word worksheet ‘My Rainforest Conservation Letter’ to help you complete your letter individually.
After you have completed your letter, save it to your User Area for easy access to in the future
You should have by now successfully completed your research and letter to the Government campaigning for the conservation of your Rainforest.
Now you will record your knowledge using a bar-chart.
Look back at your ‘Rainforest Estimates’ from the beginning. You will use the same matter that you used to record percentages on before (houses, plants, trees etc).
You will use your research to alter your estimates to the correct proportions and record them on your bar chart.
Plenary Cont. Your bar-chart should be similar to the one below:
You will then record your information on Microsoft Word ‘My Rainforest Results’ worksheet. You can now compare your results to your estimates, and see if your results are similar (if they are it obviously shows that you were a Rainforest Genius from the start!)
