Duration: Preparation time 20 minutes, activity time 40 minutes.
Setting: A large room or outside. |
Summary
Using a number of native plant and animal cards
and a ball of string students simulate a working
ecosystem.
(** Download the full set of plant and animal
cards below)
Each
card has the common name, scientific name and
where available the Aboriginal name - mostly from
the Melbourne region (Woiwurrong), although some
are from the south west of Victoria (Gunditjmara).
Objectives
Students will gain an understanding of ecosystems
and the relationships between plants and animals.
The food web will also provide an understanding
of impacts on ecosystems and their lasting effects.

Connections
All food webs begin with plants - this enables
students to understand the connections between
the range of plant and animal species that are
found all around us. Students will be able to
understand the food web as more than a two-dimensional
system. It will also give them the opportunity
to place themselves in the food web and see the
impacts they may have on a range of systems around
them.
Activities:
| 1. |
Allocate
a plant/animal card to each student (the cards
can be laminated if you would like them to
last longer) |
| 2. |
Punch
two holes in the top of each card and tie
a length of string to fit around the students
neck |
| 3. |
Ask students to make a large circle |
| 4. |
Ask
students to read cards to themselves and find
out where their animal lives, what they eat,
and sometimes, what eats them |
| 5. |
Place
1 or 2 students in the centre of the circle
with the balls of string - they can be the
sun or the energy transfer |
| 6. |
Start
with any student and ask them to identify
where they sleep or what they eat (ie Kangaroo
eats Tussock grass) |
| 7. |
One
of the students in the middle gives one end
of the string to the Kangaroo and takes the
other end to the Tussock grass and asks them
to hold onto the string |
| 8. |
Identify
something else that uses the tussock grass
(ie the Eastern Barred Bandicoot nests in
the tussock grass) |
| 9. |
Roll
out the string and ask the Eastern Barred
Bandicoot to hold onto the string. |
| 10. |
What
does the EBB eat - insects - take the string
to the invertebrate person and ask them to
hold it |
| 11. |
If this is the end of the line then cut the
string and start again with a new animal and
a new web |
| 12. |
After
a while you will have a range of webs. Then
start adding in effects such as - what if
the red gum dies? Everyone attached to the
red gum has to sit down - do this with a range
of impacts such as: |
|
| »
|
Decrease
in water quality |
| » |
Loss
of tussock grass |
| » |
Pesticides
kill the invertebrates |
| » |
The
red gums are cut down |
| » |
Koalas
eat all of the manna gums |
|
Wrap
up
Ask students to design their own food web - what
do they eat - what else relies on that food, what
does that food eat/need to survive, where did
that food come from? As a class they could make
a wall chart of the web of life that they are
a part of - they could make the links on the chart
with string or wool.
Assessment
| »
|
Identify
the relationships of a range of familiar systems
(the garden, school yard, farm) |
| » |
Students
can explain what they have learnt by drawing
or writing their own food web applied to a
familiar situation. |
