1 Unit 6 Prtil Biology n Investigtive Skills 10.7 for the iniviul investigtion Reserh n rtionle There is some ttempt to provie rtionle for the hoie of investigtion in terms of its sope n its reltion to iologil priniples. 0 2 mrks Few soures re onsulte n their sope is limite in proviing ontext for the investigtion, to ssist with the plnning or exeution of lortory or fiel work, or in informing the interprettion of results. There is prtil rtionle for the hoie of investigtion. The iologil kgroun to the investigtion is evelope to some extent. 3 6 mrks Conept n Context pproh Informtion gthere from some relevnt soures hs some ering on the ontext for the investigtion, n ssists, in limite wy, with the plnning or exeution of lortory or fiel work, or to inform the interprettion of results. The rtionle for the investigtion is ler, in terms of its sope n reltionship to iologil priniples. Severl relevnt soures re onsulte, n re use to provie ontext for the projet, to ssist with the plnning or exeution of lortory or fiel work, n to inform the interprettion of results. The rtionle for the investigtion is lerly justifie in terms of its sope n pproprite iologil priniples re isusse. Aitionl soures, eyon those tht were most reily to hn or were initilly suggeste y the teher, re selete. The mteril hosen is selete for its relevne to the investigtion n it is use effetively to provie ontext for the projet, to ssist with the plnning or exeution of lortory or fiel work, n to inform the interprettion of results. 7 9 mrks mrks 92

2 Prtil Biology n Investigtive Skills Unit 6 Plnning There is some ttempt to pln n to selet the metho or pprtus hosen. Some relevnt vriles re ientifie. 0 2 mrks Some potentil sfety hzrs n the steps to voi or minimise them re ientifie. A tril experiment my e rrie out. There is pln for the investigtion, with some explntion of the seletion of pprtus n methos. There re some etils of how vriles re to e ontrolle, mnipulte or tken into ount n how relevnt oservtions re to e me. Most potentil sfety hzrs, n the steps to voi or minimise them, re ientifie. A tril experiment is performe tht hs some ering on the plnning of the projet. There is ler pln of tion, oth for n initil tril phse n for the min perio of t olletion. Apprtus selete n methos hosen re pproprite to the investigtion. There is isussion out how vriles re ontrolle, mnipulte or tken into ount n out the olletion of relevnt oservtions or t. All potentil sfety hzrs re ientifie, n suitle steps tken to voi or minimise them. A well-thought out tril is onute in vne of the min t olletion phse, n is use to inform the plnning of the investigtion.,, ) There is eviene of thought n ingenuity in the esign of experiments or the reoring of t, with goo ttention to etil inluing the wy in whih vriles re ontrolle, mnipulte or tken into ount n how relevnt oservtions re me or t ollete. Apprtus is evise or moifie to suit the projet s neessry. 3 6 mrks 7 9 mrks mrks Conept n Context pproh Eexel GCE in Biology Eexel Limite 2010 Setion C 93

3 Unit 6 Prtil Biology n Investigtive Skills Oserving n reoring Some pproprite mesurements n oservtions re reore, whih re equte for the metho use n resonly urte. 0 2 mrks There is some repeting or heking of vlues otine. Mesurements n oservtions re reore methoilly n urtely in pproprite units, n some thought is given to preision n repetility. 3 6 mrks A resonle numer n rnge of oservtions n mesurements re rrie out. Any nomlous results re note. There is some pproprite moifition of proeures for t olletion if neessry. Conept n Context pproh Interpreting n evlution Oservtions n mesurements re rrie out over suitle rnge of vlues or onitions. Suffiient oservtions n mesurements re me to llow onlusion. Numeril results re reore to n pproprite egree of preision. Mesurements n oservtions re repete s pproprite. Any nomlous results re note n investigte. If prolems rise in the mking of mesurements or oservtions, proeures re pte to ensure t is relile. There is some t proessing. Sttistil nlysis is only omplete with etile guine. Applition of lulte sttistil vlues is present, though limite or onfuse. There is n ttempt to pply iologil priniples. Some onlusions re stte. There is some wreness of the limittions of experimentl results n onlusions. Dt is proesse with some thought s to hoie of metho. The hosen sttistil test(s) my e inpproprite or provie limite nlysis of the stte hypothesis. Clultions re lerly set out ut the interprettion of lulte vlues lks etile explntion. Some trens n ptterns re ientifie. 7 8 mrks 0 3 mrks 4 6 mrks Some ttempt is me to interpret results using iologil priniples, n to rw onlusions se on experimentl results. Conlusions re supporte y results. The limittions of results, n onlusions se upon them, re reognise. Any limittions of methos re reognise. Dt re proesse using pproprite methos tht revel trens n ptterns. The hosen sttistil tests re pproprite to the t to e nlyse n the hypothesis to e teste. Clultions of sttistil tests re lerly set out n interprete, using null hypothesis n 5 per ent onfiene levels where pproprite. Trens n ptterns re ientifie. 7 9 mrks Results re interprete using iologil priniples n onepts of Avne GCE stnr. Relevnt iologil priniples re pplie orretly throughout. Conlusions re supporte y results. The limittions of results, n onlusions se upon them, re reognise n evlute. Any limittions of the proeure re ommente upon, n sensile moifitions suggeste. 94

5 C Biology unit ontent Aministrtion of internl ssessment 1 Internl stnristion Tehers hoosing the option of mrking the internl ssessment work themselves must show lerly how the mrks hve een wre in reltion to the ssessment. If more thn one teher in entre is mrking stuents work, there must e proess of internl stnristion to ensure tht there is onsistent pplition of the ssessment. 2 Authentition All nites must sign n uthentition sttement. Sttements relting to work not smple shoul e hel seurely in your entre. Those whih relte to smple nites must e tthe to the work n sent to the moertor. In orne with revision to the urrent Coe of Prtie, ny nite unle to provie n uthentition sttement will reeive zero reit for the omponent. Where reit hs een wre y teher to smple work without n ompnying uthentition sttement, the moertor will inform Eexel n the mrk will e juste to zero. 3 Further informtion Centres requesting moertion of stuents work will e require to sumit mrks n moertion smple y mi-my. Eexel-mrke reports will e require to e sumitte to n exminer ppointe y Eexel y mi-my. Further guine for sumission of stuent work n mrks will e pulishe in the Eexel Informtion Mnul. For more informtion on nnottion, uthentition, mrk sumission n moertion proeures, plese refer to the Eexel AS n GCE in Biology: Instrutions n ministrtive oumenttion for internlly ssesse units oument, whih is ville on the Eexel wesite.
