HYPOTHESIS Ifwemixtherightamountofcolorstogether,thenwewillbeabletocreatearainbow. PROCEDURES Part1: 1.Label6testtubesinorder:A,B,C,D,E&F. 2.Fillabeakerhalffullwithwater.Usethistorinseyourgraduatedcylinderandtest tubes. 3.Thesecondbeakerisforcontaminatedwastewater. 4.IntotesttubeA,measure17mLofREDliquid. 5.IntotesttubeC,measure11mLofYELLOWliquid. 6.IntotesttubeE,measure13mLofBLUEliquid. Part2: 1.FromtesttubeC,measure4mLandpourintotesttubeD. 2.FromtesttubeE,measure7mLandpourintotesttubeD.Swirl. 3.FromtesttubeE,measure4mLandpourintotesttubeF. 4.FromtesttubeA,measure7mLandpourintotesttubeF.Swirl. 5.FromtesttubeA,measure8mLandpourintotesttubeB. 6.FromtesttubeC,measure3mLandpourintotesttubeB.Swirl. 7.SAVEyourresults.MeasurethecontentsofeachtesttubeandrecordhowmanymL werefoundineachtesttube. 8.Answerquestions.

ANALYSIS 1. Namethecolorsthatyoucreated. Wecreatedthecolorsred,orange,yellow,green,blueandpurple 2. HowmanymLofliquidwereineachtesttubeatthestartofthislab? Atthestartofthislabtherewas17mLofliquidintesttubeA,11mLintesttubeC,and 13mLintesttubeE. 3. Whyisitimportanttofollowdirectionsexactly? Ifyoudon’tfollowthedirectionsexactlyhowtheyareyoucanmessthewholelabupwith justonemistake. 4. Whatwouldhavehappenedifyourmeasurementswerenotcorrect? Ifyourmeasurementsarenotcorrectyourdatawon'tbeeither. 5. Lookatyourhands.Doyouhaveanystainsonyourhands?Ifso,thosestains representchemicalsthatwouldbeonyourskinrightnow!

Idon’thavestainsonmyhands. 6. HowmanyTOTALmLofliquiddidyouhaveattheendofthelab?39.7mL Howmanyshouldyouhave?41mL 7. Whataresomereasonswhyyoumayhavemoreorlessthanwhenyoustarted? Ithinkwemayhavelessthanwhatwasestimatedbecausewecouldhaveaddedless mLthanweneededbymistake. Conclusion:23sentencesonwhatyoulearned. Ilearnedaboutwhydirectionsareimportantandhowtofollowthem.Ialsolearnedthatisyour measurementisn’tcorrect,yourdatawillbemessedupaswell.Forexample,ouroutcomewith theoutcomeweweresupposedtohavewerenotthesame,wehadlessthanweneededto. Thiswasbecauseofourinaccuratemeasurements.Althoughwedidnotgeteverythingentirely correct(whichisokay)whatwelearnedtodowashowtocompletealab....
