3 NOAA/NSTA Sympsium: GPS and Gedesy fr Dummies: D Yu Knw Where Yu Are? NSTA Natinal Cnference n Science Educatin, St. Luis, MO Natinal Science Educatin Standards Addressed: Cntent Standards, Grades 5-8 Cntent Standard A: Abilities Necessary t d Scientific Inquiry Use apprpriate tls and techniques t gather, analyze, and interpret data. Develp descriptins, explanatins, predictins and mdels using evidence. Think critically and lgically t make the relatinships between evidence and explanatins. Understanding abut Scientific Inquiry Scientific explanatins emphasize evidence, have lgically cnsistent arguments, and use scientific principles, mdels, and theries. The scientific cmmunity accepts and uses such explanatins until displaced by better scientific nes. When such displacement ccurs, science advances. Cntent Standard E: Science and Technlgy As a result f activities in grades 5-8, all students shuld develp Understandings abut science and technlgy Science and technlgy are reciprcal. Science helps drive technlgy, as it addresses questins that demand mre sphisticated instruments and prvides principles fr better instrumentatin and technique. Technlgy is essential t science, because it prvides instruments and techniques that enable bservatins f bjects and phenmena that are therwise unbservable due t factrs such as quantity, distance, lcatin, size, and speed. Technlgy als prvides tls fr investigatins, inquiry, and analysis. Technlgical slutins have intended benefits and unintended cnsequences. Sme cnsequences can be predicted, thers cannt. Cntent Standard F: Science in Persnal and Scial Perspectives As a result f their activities in grades 5-8, all students shuld develp understanding f Science and Technlgy in Sciety Technlgy influences sciety thrugh its prducts and prcesses. Technlgy influences the quality f life and the ways peple act and interact. Technlgical changes are ften accmpanied by scial, plitical, and ecnmic changes that can be beneficial r detrimental t individuals and t sciety. Scial needs, attitudes, and values influence the directin f technlgical develpment. Science and technlgy have advanced thrugh cntributins f many different peple, in different cultures, at different times in histry. Science and technlgy have cntributed enrmusly t ecnmic grwth and prductivity amng scieties and grups within scieties. Cntent Standard G: Histry and Nature f Science As a result f their activities in grades 5-8, all students shuld develp understanding f Nature f science 3

NSTA Natinal Cnference n Science Educatin, St. Luis, MO Scientists frmulate and test their explanatins f nature using bservatin, experiments, and theretical and mathematical methds. Althugh all scientific ideas are tentative and subject t change and imprvement in principle, fr mst majr ideas in science, there is much experimental and bservatinal cnfirmatin. Thse ideas are nt likely t change greatly in the future. Scientists d and have changed their ideas abut nature when they encunter new experimental evidence that des nt match their existing explanatins. Histry f Science Many individuals have cntributed t the traditins f science. Studying sme f these individuals prvides further understanding f scientific inquiry, science as a human endeavr, the nature f science, and the relatinships between science and sciety. Cntent Standards, Grades 9-12 Cntent Standard A: Abilities Necessary t d Scientific Inquiry Frmulate and revise scientific explanatins and mdels using lgic and evidence. Understanding abut Scientific Inquiry Scientists usually inquire abut hw physical, living, r designed systems functin. Cnceptual principles and knwledge guide scientific inquiries. Histrical and current scientific knwledge influence the design and interpretatin f investigatins and the evaluatin f prpsed explanatins made by ther scientists. Mathematics is essential in scientific inquiry. Mathematical tls and mdels guide and imprve the psing f questins, gathering data, cnstructing explanatins and cmmunicating results. Cntent Standard E: Science and Technlgy As a result f activities in grades 9-12, all students shuld develp Understandings abut science and technlgy Science ften advances with the intrductin f new technlgies. Slving technlgical prblems ften results in new scientific knwledge. New technlgies ften extend the current levels f scientific understanding and intrduce new areas f research. Science and technlgy are pursued fr different purpses. Scientific inquiry is driven by the desire t understand the natural wrld, and technlgical design is driven by the need t meet human needs and slve human prblems. Technlgy, by its nature, has a mre direct effect n sciety than science because its purpse is t slve human prblems, help humans adapt, and fulfill human aspiratins. Technlgical slutins may create new prblems. Science, by its nature, answers questins that may r may nt directly influence humans. Smetimes scientific advances challenge peple s beliefs and practical explanatins cncerning varius aspects f the wrld. Technlgical knwledge is ften nt made public because f patents and the financial ptential f the idea r inventin. Scientific knwledge is made public thrugh presentatins at prfessinal meetings and publicatins in scientific jurnals. 4

NSTA Natinal Cnference n Science Educatin, St. Luis, MO Cntent Standard G: Histry and Nature f Science As a result f their activities in grades 9-12, all students shuld develp understanding f Nature f scientific knwledge Scientific explanatins must meet certain criteria. First and fremst, they must be cnsistent with experimental and bservatinal evidence abut nature, and must make accurate predictins, when apprpriate, abut systems being studied. They shuld als be lgical, respect the rules f evidence, be pen t criticism, reprt methds and prcedures, and make knwledge public. Explanatins n hw the natural wrld changes based n myths, persnal beliefs, religius values, mystical inspiratin, superstitin, r authrity may be persnally useful and scially relevant, but they are nt scientific. Because all scientific ideas depend n experimental and bservatinal cnfirmatin, all scientific knwledge is, in principle, subject t change as new evidence becmes available. The cre ideas f science such as the cnservatin f energy r the laws f mtin have been subjected t a wide variety f cnfirmatins and are therefre unlikely t change in the areas in which they have been tested. In areas where data r understanding are incmplete, such as the details f human evlutin r questins surrunding glbal warming, new data may well lead t changes in current ideas r reslve current cnflicts. In situatins where infrmatin is still fragmentary, it is nrmal fr scientific ideas t be incmplete, but this is als where the pprtunity fr making advances may be the greatest. Histrical perspectives Occasinally, there are advances in science and technlgy that have imprtant and lnglasting effects n science and sciety. Examples f such advances include the fllwing: Cpernican revlutin, Newtnian mechanics, Relativity, Gelgic time scale, Plate tectnics, Atmic thery, Nuclear physics, Bilgical evlutin, Germ thery, Industrial revlutin, Mlecular bilgy, Infrmatin and cmmunicatin, Quantum thery, Galactic universe, and Medical and health technlgy. Natinal Gegraphy Standards Addressed: Grades 5-8 Standard 1: The Wrld in Spatial Terms: A. Describe the essential characteristics and functins f maps and gegraphic representatins, tls and technlgies by being able t: Explain map essentials (scale, directinal indicatrs, symbls). C. Use gegraphic tls and technlgies t pse and answer questins abut spatial distributins and patterns n Earth by being able t: Use maps t make and justify decisins abut the best lcatin fr facilities. Principles and Standards fr Schl Mathematics: Gemetry Standard fr Grades 3-5 Specify lcatins and describe spatial relatinships using crdinate gemetry and ther representatinal systems. Describe lcatin and mvement using cmmn language and gemetric vcabulary. Make and use crdinate systems t specify lcatins and t describe paths. 5
