ENBE Project One - NatureLow Jia Cheng0314883FNBE 04/13Generation Y

Because most of the pictures of the site , experiment , lost due to phone drop into the water , I will try to describe my individual work and experiment well .

Idea – research before site visit Idea-I want to know the amount of the

creature at the site. biological population formula Capture , Mark , Release , Recapture

Number of creature in 1st sample x Number of creature in 2nd sample Number of Marked creature recapture

Choose siteThe size have a lot of creature , easy for my experiment.

1st thing to do , the 5 sense See Hear Taste Smell Feel

SEE-What I see at my site , is the combination of everything , animal , plant , water , rocks , everything about the nature .-I see there are different type of organisms ,with different quantity , some creature has a lot quantity , some only few . There are also different size of creature.-Something that interested me is the fishes , the river flow in high speed , but the fishes still can swim in the river freely.

hear When I 1st stand at my site , I hear the

wind , the sound of scrubbing of the leafs.

Something annoying me is I heard the sound of vertical , cause opposite the side is the highway .

When I play is the river , I face close to the water , the sound of the water flow , is feel very relax.

taste I taste the river water , its feel tasteless

in the beginning , after awhile in the mouth , its feel a bit sour but fresh.

I taste the rubber tree leaf , its feel bitter and astringent .

I taste the dry rubber tree leaf , its feel bitter the same , and full of soil taste

smell I smell fresh air , of course fresh air

means the smell of the green plant , the oxygen and ozone smell .

Ozone smell in the morning is little smelly but feel fresh and nice.

Evening , u can smell the oxygen fresh hot.

feel I touch the sand in the river , maybe the

flow of water and my hand is totally submerged in the water , so the sand actually feel sandy and dry. Very smooth.

I was cut by the bamboo plant , its leaf feel rough.

Plant A plant had attracted me. When I 1st walk into the site , I saw a

small plant’s leaf facing downward, is very different to the other plants.

I go near and look at it , and broke the branch .

White colour fluid actually flow out from the plant, its sticky.

Sketching

Leaf of old rubber tree (similar)

Plant conclusion The leaf is similar to the old rubber plant

tree The white colour fluid is actually the

young latex. So , it’s a

YOUNG RUBBER TREE

Insect Something attract me is there are a lot

butterflies at the site, with different type.

the most colour one attreacted me. Very detail of the colour part , with the

line on the butterfly wing are interesting.

detail

Habitat

Insect conclusion I found the leaf actually a lot of holes

which ate by caterpillar means that there is the habitat for butterfly.

It is a Yellow butterfly.

Experiment 1 -Fish face force in the water compare to human-if compare to human, human face 560 gram every second .

Calculation

Experiment 2 The population in the site. Three part 1st part , count the creature that

countable in the site 2nd part , using quadrat to count the

creature that a lot . 3rd part , use the capture , mark ,

release , recapture method .

1st part Creture: Rubber tree Butterfly Dragonfly fern Cogan grass Bony fish Catfish grass

2nd part Weed is very hard to count The picture bellow show that land is

about 50% 5 weeds in a 1m x 1m quadrat . So that 5 x 50 = 250 weed

Quadrat

3rd part Ant is a lot . Use the method by: Use cotton bud to mark ants by organic

harmless white ink Count the ant that have mark next day .

formula

Interpreting data Easy to analyses my date , I put it into a

graph. I find the gradient of the graph to know

the balance amount at the site.

colour represent creature

Graph y=-515x

Experiment 3 Investigate the size of the creature , Using meter rule and measuring tape Record the data in graph

Problem came out Because due to the theory , size is

inversely proportional to the population ,

The animal don have problem , but the plant have different data

So I separate them into two graph

Graph y=35x(increasing) correct data

Graph y=583x

The graph not increasing with sequence

Reason:10x10m cant get the most accurate data.

How to solve ?Find gradient

Get the accurate data because gradient is to balance the data.

Final graph for size I put in the animal

and the plant graphand find the balancegradient = size ofanimal and plant

Gradient y=500xcalculated

4th experiment During the experiment 2 and 3,

I found there are relationship between them

To find out the relationship , I combine the two graph .

Compare Both gradient

actually wenttwo different way(+,-)

So I make a relationship on both graph by make them against each other In the graph , we can see clearly, Population is inversely proportional to

size.

Conclusion The bigger the size of the creature ,the

smaller the population of the creature.

I Show my research to my group and we make it as infography .

I use the infography to present because some of my sketching lost, and some is quite messy .

My real sketching work All my research is calculate by myself ,

not from internet A bit messy , all the number data is so

annoying .

Some but not all :p

Thanks For Watching :D
