2. Because most of the pictures of the site , experiment , lost due to phonedrop into the water , I will try to describe my individual work andexperiment well .
3. Idea research before site visit Idea-I want to know the amount of thecreature at the site. biological population formula Capture , Mark , Release , Recapture Number of creature in 1st sample x Number of creature in 2nd sampleNumber of Marked creature recapture
4. Choose siteThe size have a lot of creature , easy for myexperiment.
5. 1st thing to do , the 5 sense See Hear Taste Smell Feel
6. SEE-What I see at my site , is the combination ofeverything , animal , plant , water , rocks , everything about the nature .-I see there are different type of organisms ,withdifferent quantity , some creature has a lotquantity , some only few . There are alsodifferent size of creature.-Something that interested me is the fishes , theriver flow in high speed , but the fishes still canswim in the river freely.
7. hear When I 1st stand at my site , I hear thewind , the sound of scrubbing of the leafs. Something annoying me is I heard thesound of vertical , cause opposite the sideis the highway . When I play is the river , I face close to thewater , the sound of the water flow , is feelvery relax.
8. taste I taste the river water , its feel tasteless inthe beginning , after awhile in themouth , its feel a bit sour but fresh. I taste the rubber tree leaf , its feel bitterand astringent . I taste the dry rubber tree leaf , its feelbitter the same , and full of soil taste
9. smell I smell fresh air , of course fresh air meansthe smell of the green plant , the oxygenand ozone smell . Ozone smell in the morning is little smellybut feel fresh and nice. Evening , u can smell the oxygen freshhot.
10. feel I touch the sand in the river , maybe theflow of water and my hand is totallysubmerged in the water , so the sandactually feel sandy and dry. Very smooth. I was cut by the bamboo plant , its leaffeel rough.
11. Plant A plant had attracted me. When I 1st walk into the site , I saw a smallplants leaf facing downward, is verydifferent to the other plants. I go near and look at it , and broke thebranch . White colour fluid actually flow out fromthe plant, its sticky.
12. Sketching
13. Leaf of old rubber tree (similar)
14. Plant conclusion The leaf is similar to the old rubber planttree The white colour fluid is actually the younglatex. So , its aYOUNG RUBBER TREE
15. Insect Something attract me is there are a lotbutterflies at the site, with different type. the most colour one attreacted me. Very detail of the colour part , with theline on the butterfly wing are interesting.
16. detail
17. Habitat
18. Insect conclusion I found the leaf actually a lot of holeswhich ate by caterpillar means that thereis the habitat for butterfly. It is a Yellow butterfly.
19. Experiment 1-Fish face force in the water compare tohuman-if compare to human, human face 560gram every second .
20. Calculation
21. Experiment 2 The population in the site. Three part 1st part , count the creature thatcountable in the site 2nd part , using quadrat to count thecreature that a lot . 3rd part , use the capture , mark , release, recapture method .
22. 1st part Creture: Rubber tree Butterfly Dragonfly fern Cogan grass Bony fish Catfish grass
23. 2nd part Weed is very hard to count The picture bellow show that land is about50% 5 weeds in a 1m x 1m quadrat . So that 5 x 50 = 250 weed
24. Quadrat
25. 3rd part Ant is a lot . Use the method by: Use cotton bud to mark ants by organicharmless white ink Count the ant that have mark next day .
26. formula
27. Interpreting data Easy to analyses my date , I put it into agraph. I find the gradient of the graph to knowthe balance amount at the site.colour represent creature
28. Graph y=-515x
29. Experiment 3 Investigate the size of the creature , Using meter rule and measuring tape Record the data in graph
30. Problem came out Because due to the theory , size isinversely proportional to the population , The animal don have problem , but theplant have different data So I separate them into two graph
31. Graph y=35x(increasing)correct data
32. Graph y=583x The graph notincreasing withsequence Reason:10x10mcant get the mostaccurate data. How to solve ?Find gradient Get the accuratedata becausegradient is tobalance the data.
33. Final graph for size I put in the animaland the plant graphand find the balancegradient = size ofanimal and plant Gradient y=500xcalculated
34. 4th experiment During the experiment 2 and 3,I found there are relationship betweenthem To find out the relationship , I combine thetwo graph .
35. Compare Both gradientactually wenttwo differentway(+,-)
