Tasmanian Biodiversity
This learning sequence provides opportunities for students to
investigate some characteristics of Tasmania’s flora and fauna, along
with the interactions that occur between different organisms. They
consider how the adaptations that plants and animals have assist
their survival in the particular habitat where they are found.
Topic
Students learn about ways in which scientists study plants and
animals, and progress to conducting their own ecological study.
The unit culminates with students identifying threats to biodiversity
in Tasmania and considering the likely impact of a proposed
development.
*Teacher Note: A major part of this unit involves working with the staff
of the Molesworth Environment Centre and visiting the Centre. Teachers
should contact Molesworth staff to book class visits well in advance.
There is a cost involved for the use of the centre.

backpacks

Learning opportunities
how ecologists
work
Create backpacks as described in the General Instructions section of the Ecologists Backpack
Activities document. A similar activity is available from the Wildlife Wizards website,
http://www.sandiegozoo.org/teachers/classroom_activities.html but the attached one has been
modified for the Tasmanian context.
Teacher note:
For greater effect,
assemble actual backpacks
and equipment.
Procedure
1. Ask students questions such as: “Who has been to a Tasmanian national or wildlife park?
What native animals did you see? (You might like to start a class list/word wall of native
animals) How do scientists group Tasmanian animals? What features do different animals have
in common? How are they different?
2. Discuss Tasmanian researchers, using ideas such as: There are people who take care of the
animals at the park. Did you know there are also people working all over Tasmania to learn
more about these animals in the wild to help understand and protect them? We call these
people ‘researchers’. What wildlife researchers do you know of? e.g. University of Tasmania,
Parks and Wildlife Service, DPIW, CSIRO, Australian Antarctic Division, TAFI, ForestryTas
3. For this unit, we need to bring out the researcher in you. A researcher needs many things when
going out on an exploration or field trip. Can anyone guess what some of those items may be?
(Take a few answers)
4. Break students into four teams. Each team gets a backpack containing items that would
be used by a particular Tasmanian researcher. Each team has 10-15 minutes to review
the items in their backpack. They discuss what the researcher is studying and in what
kind of habitat.


ability to identify how
the features that an
organism has suit it to
particular way of life
A similar optional activity can be found on the Monterey Bay Aquarium website, where students
design fish suited for particular habitats:
http://www.mbayaq.org/lc/teachers_place/activity_fish_mystery.asp
Discuss adaptations that different Tasmanian animals and plants have – use stuffed animals
(available for loan from Museums) or photos. Information on Tasmanian wildlife is available at:
http://www1.parks.tas.gov.au/wildlife/wildlife.html
For example:

Kangaroo – fur keeps them warm, strong back legs allow jumping, pouch provides place
for young, tail provides balance, homoeothermic (warm blooded) so they can function at
different temperatures.

Grasshopper – big hind legs allow jumping, biting mouthparts allow chewing of leaves,
colour provides camouflage, compound eyes allow predators to be spotted quickly.

Little penguins – streamlined body shape reduces energy required to swim through
water, oily waterproof feathers provide insulation, counter-shading for camouflage, come
ashore in groups after dark to avoid predators.

Blue gum – waxy covering on leaves reduces water loss and protects against insects,
height allows access to more sunlight.
How can we group the different kinds of adaptation? (Adaptations can be grouped into three
broad categories: structural, physiological and behavioural.) Identify which group each of the
above adaptations fall into.
Students complete worksheet (2 options attached) showing the structural, physiological and
behavioural adaptations displayed by different organisms. Examples of Tasmanian organisms can
be viewed on a slideshow at: http://www1.parks.tas.gov.au/wildlife/slideshow/ss01.html

or
Each student is assigned a Tasmanian plant or animal and carries out a library research project to
identify the range of adaptations that a particular organism possesses, and then produces a
poster/diagram/powerpoint or similar to display in the classroom.
5. Tasmanian
habitats
Brainstorm some different Tasmanian habitats – view videos of plants/animals in those habitats.
Consider the adaptations that the plants and animals living in those habitats need.

Give students a range of Tasmanian plant and animal specimens (photos or real) and ask students
to organise them into groups based on how similar they are. Share the method they used to
group.
Explain some of the major groups that scientists use. e.g. plants/animals,
vertebrates/invertebrates, fish/birds/reptiles/mammals/amphibians,
arthropods/annelids/echinoderms/molluscs/coelenterates,
crustaceans/arachnids/insects/myriapods, placentals/marsupials/monotremes.
Demonstrate how to use a key to identify different animal groups.

available in bookshops) to identify Tasmanian eucalypts in your local area
http://fcms.its.utas.edu.au/scieng/plantsci/newsdetail.asp?lNewsEventId=2536

Use the Parks and Wildlife Service Tasmanian Mammals poster to identify photos of
local mammals

Use the Frogs of Tasmania poster or visit
http://www1.parks.tas.gov.au/wildlife/frogs/frogs.html to identify some frogs from your
local area by their calls

Use various guidebooks to identify invertebrates found in your school (e.g. Wings for
insects)
Use the Gould League food web activity to develop an understanding of food chains and webs
and the terms producer/herbivore/carnivore/top order predator. See
http://www.gould.edu.au/foodwebs/kids_web.htm
View a video on food chains/food webs. e.g. Brain pop - http://www.brainpop.com/
Use food web/food chain interactive games to investigate food chains. For example
http://www.ecokidsonline.com/pub/eco_info/topics/frogs/chain_reaction/index.cfm or Use
Learning Federation Objects such as those listed in the Resources section. To access these
objects, go to the eCentre, then the Resource Centre and type the object’s name into a search.
Use the drawings and photos of Tasmanian plants and animals provided by the Parks and Wildlife
Service Tasmania (attached) to create food chains / food webs which show the energy flow
through an ecosystem. If pictures are glued to magnets they can be manipulated on a magnetic
whiteboard. Give students the animal diet cards (attached) which list the diet of the animals
shown in the pictures and have them use whiteboard markers to draw in arrows that show
energy flow though the food web (remember that the arrows show where the energy goes to,
so, for example, an arrow would point form grass to a kangaroo). If magnets are not available,
use blutak. Students could record this food web individually in their books.

Possible extension might include research on bioaccumulation. Students could be asked to
explain why the use of toxic chemicals can cause greater problems for animals higher up the
food chain.
Note:
The food web cards and pictures would be useful for a variety of other activities. These activities
need to be adapted to suit your class, but some possibilities include:
9. Ecological study
techniques

What’s my rule? A concept attainment game. Students place some or all of the cards
and/or pictures into one or more groups according to a ‘rule’ (such as ‘marsupials’, ‘toporder predators’, ‘herbivores’, ‘invertebrates’) and other students have to guess the
‘rule’ used.

Celebrity heads. Students have a matching picture and information card placed on
them so that they cannot see it. This could be done using masking tape on their back, or
using a large string or elastic loop which they wear around their neck. They ask other
students questions about their organism to try to gain enough information to guess
‘their’ identity. This can be done with a ‘panel’ of about three students, or it can be done
as a whole class with students mingling simultaneously and sitting down once they have
‘found’ their identity.

Memory Game. The pictures and information cards are placed face down, and
students take it in turns to lift two cards (a picture and an information card). If the two
cards correspond to the same organism, the student keeps the pair. If they do not
match, they are placed back in their original spots. The winner is the person with the
most pairs of cards.
Visit an area such as the Molesworth Environment Centre to carry out an ecological study.
Some possible activities that Molesworth staff can facilitate would include:

conducting an
ecological inquiry

perform a transect survey to look at the plants and animals present in a particular area e.g.
up a slope,

data collection

perform a quadrat survey to investigate leaf litter invertebrates.

shake trees to collect and identify the invertebrates living in different species of trees.

Diamond Ranking of issues: Once students have brainstormed potential issues about the local or
topical development, they choose the nine most important issues. Individual students or groups
then ‘rank’ these issues according to importance using the attached Diamond Ranking sheet.
This forces students to decide which issues are most important, and can be a useful introductory
activity for a class discussion, or culminating activity following a class discussion.
The most important issue is placed at the top, the next two most important are underneath this,
and so on.
Organise a class role play in which participants take on the role of different interest groups and
speak at a public meeting to present their group’s viewpoint on the proposal. This could be
modelled on the Whale Bay activity at http://www.mesa.edu.au/cams/module9/resources.htm
