Befre starting yur pret, yu need t un derstand the sientifi ethd. This setin uses exaples t illustrate and explain the basi steps f the sientifi ethd. The

12、sientifi ethd is the “tl” that sientists use t find the answers t questins. It is the press f thinking thrugh the pssible slutins t a prble and testing eah pssibility t find the best slutin. The sientifi ethd invlves the fllwing steps: ding researh, identifying the prble, stating a hypthesis, n-duti

13、ng pret experientatin, and reahing a nlusin.ResearhResearh is the press f lleting infratin fr yur wn experienes, knwledgeable sures, and data fr explratry experients. yur first researh is used t selet a pret tpi. This is alled tpi researh. Fr exaple, yu bserve a blak grwth n bread slies and wnder hw

14、 it gt there. Beause f this experiene, yu deide t learn re abut ld grwth. yur tpi will be abut fungal reprdutin. (Fungal refers t plant-like rganiss alled fungi, whih annt ake their wn fd, and reprdutin is the aking f a new ffspring.) AUTIN: If yu are allergi t ld, this is nt a tpi yu wuld investiga

15、te. hse a tpi that is safe fr yu t d.After yu have seleted a tpi, yu begin what is alled pret researh.

The result f this experient and ther researh give yu the needed infratin fr the next step identifying the prble.PrbleThe prble is the sientifi questin t be slved. It is best expressed as an “p

17、en-ended” questin, whih is a questin that is answered with a stateent, nt ust a yes r a n.HypthesisA hypthesis is an idea abut the slutin t a prble, based n knwledge and researh. hile the hypthesis is a single stateent, it is the key t a suessful pret.All f yur pret researh is dne with the gal f exp

18、ressing a prble, prpsing an answer t it (the hypthesis), and designing pret experientatin. Then all f yur pret experienting will be perfred t test the hypthesis.D state fats fr past experienes r bservatins n whih yu base yur hypthesis.D write dwn yur hypthesis befre beginning the pret experientatin.

19、Dnt hange yur hypthesis even if experientatin des nt supprt it. If tie perits, repeat r redesign the experient t nfir yur results.Pret ExperientatinPret experientatin is the press f testing a hypthesis. The things that have an effet n the experient are alled variables. There are three kinds f variab

20、les that yu need t identify in yur experients: independent, dependent, and ntrlled variables.The independent variable is the variable yu purpsely anipulate (hange). The dependent variable is the variable that is being bserved, whih hanges in respnse t the independent variable. The variables that are

21、 nt hanged are alled ntrlled variables.D have nly ne independent variable during an experient.D repeat the experient re than ne t verify yur results.D have a ntrl.D have re than ne ntrl, with eah being idential.D rganize data.Pret nlusinThe pret nlusin is a suary f the results f the pret experientat

22、in and a stateent f hw the results relate t the hypthesis.If yur results d nt supprt yur hypthesis:DNT hange yur hypthesis.DNT leave ut experiental results that d nt supprt yur hypthesis.D give pssible reasns fr the differene between yur hypthesis and the experiental results.D give ways that yu an e

23、xperient further t find a slutin.If yur results supprt yur hypthesis:yu ight say, fr exaple, “As stated in y hypthesis, I believe that light is nt neessary during the gerinatin f bean seeds. y experientatin supprts the idea that bean seeds will gerinate withut light. After seven days, the seeds test

24、ed were seen grwing in full light and in n light. It is pssible that se light reahed the n light ntainers that were plaed in a dark lset. If I were t iprve n this experient, I wuld plae the n light ntainers in a light-prf bx and / r wrap the in light-prf aterial, suh as aluinu fil.”2. n wen sientist

30、lly well.Sehw, in any parts f the wrld tday, siene and tehnlgy interventins have treated wen priarily as reipient f knwledge and have under estiated their iprtane as generatrs f innvatins and as a dynai agent f eni and sial hange. In epwering the wen with sientifi and tehnlgial skills, wen sientists

31、 and tehnlgists have a ar rle. Bitehnlgy and bisienes inluding edial, agriulture and basi researh have pened up new pprtunities.

32、ineers and innvatrs. By the end f the 20th entury, at least 25% f the astrnauts at NASA were wen, 16% sientists and engineers.f urse, it is extreely iprtant that wen sientists and tehnlgists are appreiated fr their dual rle in the siety while pursuing sientifi researh as a areer.
