wA~~ dIsSeCt fRoG aR~

few days ago..... ( wed )

i got up in da morning around 6 o'clock n went to skul as usual on tat day.. tat day was a special day for all da IJC 5SC2 students.. cos we were goin to dissect FROG,FISH n COCKROACH!!!! omg.. when i stepped into my class, i saw quite a lot of pails n containers on da floor in da classroom.. n i knew tat there were frogs inside those pails n containers.. it was kind of weird n geli for da first few periods as we had to study with da frogs.. all da frogs tat were brought by them were kinda big except for our group cos one of our group members tat was responsible of buying da frog couldn't find a big wan.. da frog tat was brought by her were so small tat dey were juz like new born frogs.. so kesian tat dey've to sacrifice for our experiment at young age.. haha.. n da funniest thing was when we were having our english class, da frog tat was brought by one of da groups ( lu ee's group ) was so hyperactive tat it jumped out of da pail n almost da whole class were screaming n sum even stood on their chairs.. but unfortunately i was not there to c da funny scene as i went out to do sthing.. when i was bak, i saw lu ee,aileen n sam were busy catching da frog bak into their pail n a lot of them in da class were standing on their chairs.. haha.. those who brought their camera kept taking pict of dis scene.. dey used up quite a lot of time of tat period n so we had less time for da eng class.. hurray!! haha.. den we went for recess.. after recess, most of them were so impatient tat dey went to da bio lab immediately.. when most of us were in da bio lab, our bio teacher,pn. aidah explained to us bout how to dissect frog,fish n cockroach.. after d explaination,we started our experiment.. first of all,we had to remove those frogs into a basin o a container so tat we can put chloroform inside da container to make those frogs pengsan.. for our group, it was so easy to remove da frogs into da container cos our frogs were so small in size.. however, one of da frog refused to get out of da plastic as if it knew tat it was goin to die.. but at last we were stil b able to remove da frog into da container n den we covered da container.. den we threw a piece of cotton ball tat was soaked with chloroform into da container n covered it again.. after waiting for a while, we tried to test whether da frogs in da container were stil awake onot by shaking da container n knocking da wall of da container.. after making sure tat there were no movement in da container anymore, we removed da cover.. when we were about to take one of da frogs out of container, da frog suddenly jumped up.. we were shocked n of cos we screamed but luckily we covered da container again b4 da frog got out of da container.. a lot of groups did scream too as da same thing happened to them too.. den we waited for quite a long time again.. while waiting, we dissected da dead fish first.. yirou did tat but we faced sum prob while dissecting as we've no skills to take out all da organs of da fish perfectly.. so, we asked for pn aidah's help.. she was so skillful tat she could even explain to us while dissecting.. after we were very very very sure tat da frog had fainted, jac took one of da frogs out n started to dissect da frog with bernice's help.. firstly, dey pinned da legs of da frog on da dissecting tray.. den, dey cut off da skin of da frog.. den dey cut da flesh of da frog.. we din c much blood coming out from da frog like other groups' frogs as our frog was so small.. after cutting off da flesh, we saw d organs of da frog.. ething was so tiny cos of da size of frog.. unlike other frogs, da heart of our frog was juz as small as an ant o even smaller than tat while other frogs' heart were bout 5-10 times bigger than our frog's heart.. n da most wonderful thing was da heart of da frog was stil beating altho we had removed it from its body.. besides da heart, we saw da stomach,liver,lungs n fats of da frog too.. sum of da groups were kinda cruel as dey cut out da frog's brain n legs.. i din dissect anything as i couldn't b hardhearted to dissect those animals.. therefore, i did another job tat's camerawoman.. i took most of da pict when dey were dissecting da frog.. but since we had 3 frogs with us, we decided to dissect another wan.. n for dis time, yi rou n siew li wil b da 'doctors'.. n i was stil da camerawoman.. dis time we chose to record da whole process cos we ad took pict for da previous wan.. when yr n sl were dissecting da 2nd frog, bernice tried to dissect da fish's stomach.. n most of da food in da fish's stomach were digested but we saw sthing tat made us fil quite surprised.. we saw another fish's tail in da fish's stomach n we came out wit one conclusion tat is....... FISH EATS FISH TOO!!! haha.. lol.. den yr n sl continue dissecting till dey had most of d organs of da frog out of its body.. den our most courageous bernice tried to dissect da cockroach.. da cockroach supposed to b dead so tat we can dissect it but jac's kakak was so cool tat she caught it alive n we tried to kill da cockroach using a lot of methods but we failed to do tat.. so we decided to put sum choroform to it too.. n den she started dissecting.. but bcos dis was da first time we dissect cockroach so we decided to ask teacher to dissect it for us again.. n pn aidah helped us.. den we saw da tracheal system of da cockroach n its organ.. it was juz so amazing tat dis was da first time for us to c so many organs of d animals.. besides frogs,fish n cockroach, we saw da chicken's heart too.. pn aidah cut da chicken's heart into 2 so tat we would b able to c da structure of a chicken's heart.. after dissecting d animals, we took a few pict with da dissected frogs n sum group pict too.. den we started to clean up.. we decided to let go of d oni frog tat was so lucky tat din get to dissect by us.. but since it was stil not awake, i brought it to a place where ppl seldom go so tat it won b stepped by others.. den i went up to bio lab again n cleaned up with them.. den we went bak to da class n i saw our add maths teacher,mr tee with his very 'black' face sitting in da class.. i tink he was angry cos we were late for his class for bout 1 hour n nobody inform him bout it.. kesian~ haha.. but he din scold us la.. juz nagged a bit den started to teach d.. den da bell rang n all of us went bak.. n a special schooling day for us ended.............
