When I went to the Dandenong Ranges I noticed that the
most dominate sphere is the Biosphere. That is because
I saw trees and plants are all around the forest and it is
covering almost 75% of the forest

Trees absorb carbon
dioxide (CO2) from the
atmosphere (air)
Carbon holds the soil
together, take up the
ground water, and absorb
damaging carbon dioxide

the soil contains

Houses were built
and that caused a
damage to the
environment
because some trees
had to be cleared
before starting
building. It also
done another
damage and that is
animals had to
leave their homes
that were the trees.
Farming caused the danger
of trees to extinct and been
replaced by other native
plants. This regeneration
also the cutting of trees
caused more light to go
into the forest which
changed it’s usual form or
cycle.
This road might have
previously been a
home for plants and
animals and now it’s
replaced by different
soil that has been
filtered.
Animals live in these
trees which might end
up being cut to use as
timber and animals
cant always find
suitable place like the
one they had before.

Hydrosphere
The most dominate spheres in here is the biosphere and
the hydrosphere. the biosphere is more. I noticed that
when we were on the fieldtrip that it was slippery and
that’s because of the water (hydrosphere). It made the
trees and leaves wet. I slipped, and as I was lifting
myself up I pushed away leaves and twigs with my hand
and noticed that further down there was dirt. That
indicated that the lithosphere is covered by a thick layer
of leaves and things.
Animals and trees are in
danger of being extinct or
replaced by other foreign
trees and animals.
People living in the
around area can
cause damage to the
ferns when their pets
are released.
These trees might be
cut to have enough
space for more
houses.
These paths are
replacing trees.
Changes in natural environment
Fuel reduction
Burns and bushfire
disasters
Impact on plants
It burns little trees and flowers but it
doesn't damage the forest. Trees and
plant like nuts can open up in the heat
and cause a re-growth in the forest so
it’s actually good for the environment
of the forest. The one and probably
only problem is that it can get out of
control.
You can tell from the name that it is
disasters. It can tern all the forest into
big cracks of timber from big trees and
into ash from the leaves and smaller
trees.
Impact on animals
It can cause the animals to move into
a different area that isn’t affected by
the fire but they can always come back
after the fire where food and trees are
grown for them.
It can kill a huge amount of animals
and it is so fast that animals can’t
really run away from it because they
could die before they even start
running. even birds can die from heat
,smoke and ash in the air when flying
away.
Impact on humans
Its good for humans because it
reduces the chance of a bush fire
when it becomes hot in the summer.
They can be affected by the smoke
and ash released into the air and their
pets might get sick from it too.
It is so disasters for humans living
around the area. It can take many lives
and it burns down houses. It basically
doesn't leave anything behind.
The affect of fuel reduction strategies on the environment are
good for the forest because it gives nutrition for the trees
and causes the tree nuts to open up as a result of the heat
and re-grows plants. However, it can get out of control and
become more dangerous,
There should be
more fire-fightersstations.
People living
around this
beautiful place
should have no
timber houses in
case a fire
spread.
There should be more
and higher fences and
other things to protect
the water within the
dam.
My first impression of the dam is that how can it be one of the cleanest dams in the world
when the fence around it is so low and it can easily be polluted by people visiting it.
It is amazing how is used by us in Melbourne every day and it’s also worrying that it could get
polluted if not taken care of well.
If a bushfire spread it’s risky that the smoke and ash is going to pollute the water and so it is
very important to find other ways to protect it more.

We can all have enough clean

had to be cut
The drought wouldn’t be as
tough on us
The population is growing and
so more water is needed.

for water only
It was built for about a million
dollars so it didn’t cost a lot
when if it was built now it would
have costed lots more.
Trees and animals that were
living there and not anymore
have a risk at being extinct .
It allows the use of water
continuously even when there
is no rain.
It costs a lot of money and it
could be damaged and it will
need more money to repair it.
EVALUATION
 Did you gather enough data in the field to complete your report thoroughly? Explain
I did gather enough information and was paying attention and I thought it was enjoyable.
 What did you enjoy most about the field trip?
I enjoyed the whole excursion and I enjoyed the sky high look out the best.
 What did you least enjoy about the fieldtrip?
 I actually liked it all but it was a little bit could and that was probably the only negative thing abut it.
 What did you like and dislike about writing this report?
I thought this report was easier than the one we did before but that could be because it was my first one. I think that
we needed at least one more lesson to make the report better.
 What could you suggest to improve this activity?
I think that it doesn’t need anything to make it better but I recon we need two Ms. KW’s to help us during the SAC :]
