3 NOAA/NSTA Sympsium: Cral Ecsystems NSTA Natinal Cnference n Science Educatin, Bstn, MA Natinal Science Educatin Standards Addressed: Cntent Standards, 5-8 Cntent Standard A: Abilities Necessary t d Scientific Inquiry Develp descriptins, explanatins, predictins and mdels using evidence. Understanding abut Scientific Inquiry Different kinds f questins suggest different kinds f scientific investigatins. Sme investigatins invlve bserving and describing bjects, rganisms, r events; sme invlve cllecting specimens; sme invlve experiments; sme invlve seeking mre infrmatin; sme invlve discvery f new bjects and phenmena; and sme invlve making mdels. Cntent Standard C: Life Science As a result f their activities in grades 5-8, all students shuld develp an understanding f Structure and Functin in Living Systems Living systems at all levels f rganizatin demnstrate the cmplementary nature f structure and functin. Imprtant levels f rganizatin fr structure and functin include cells, rgans, tissues, rgan systems, whle rganisms, and ecsystems. Cells carry n the many functins needed t sustain life. They grw and divide, thereby prducing mre cells. This requires that they take in nutrients, which they use t prvide energy fr the wrk that cells d and t make the materials that a cell r rganism needs. Specialized cells perfrm specialized functins in multicellular rganisms. Grups f specialized cells cperate t frm a tissue, such as a muscle. Different tissues are in turn gruped tgether t frm larger functinal units, called rgans. Each type f cell, tissue, and rgan has a distinct structure and set f functins that serve the rganism as a whle. Disease is a breakdwn in structures r functins f an rganism. Sme diseases are the result f intrinsic failures f the system. Others are the result f damage by infectin by ther rganisms. Reprductin and Heredity Reprductin is a characteristic f all living systems; because n individual rganism lives frever, reprductin is essential t the cntinuatin f every species. Sme rganisms reprduce asexually. Other rganisms reprduce sexually. The characteristics f an rganism can be described in terms f a cmbinatin f traits. Sme traits are inherited and thers result frm interactins with the envirnment. Regulatin and Behavir All rganisms must be able t btain and use resurces, grw, reprduce, and maintain stable internal cnditins while living in a cnstantly changing external envirnment. An rganism's behavir evlves thrugh adaptatin t its envirnment. Hw a species mves, btains fd, reprduces, and respnds t danger is based in the species' evlutinary histry. Ppulatins and Ecsystems A ppulatin cnsists f all individuals f a species that ccur tgether at a given place and time. All ppulatins living tgether and the physical factrs with which they interact cmpse an ecsystem. Ppulatins f rganisms can be categrized by the functin they serve in an ecsystem. Plants and sme micr-rganisms are prducers--they make their wn fd. All animals, 3

4 NOAA/NSTA Sympsium: Cral Ecsystems NSTA Natinal Cnference n Science Educatin, Bstn, MA including humans, are cnsumers, which btain fd by eating ther rganisms. Decmpsers, primarily bacteria and fungi, are cnsumers that use waste materials and dead rganisms fr fd. Fd webs identify the relatinships amng prducers, cnsumers, and decmpsers in an ecsystem. Fr ecsystems, the majr surce f energy is sunlight. Energy entering ecsystems as sunlight is transferred by prducers int chemical energy thrugh phtsynthesis. That energy then passes frm rganism t rganism in fd webs. The number f rganisms an ecsystem can supprt depends n the resurces available and abitic factrs, such as quantity f light and water, range f temperatures, and sil cmpsitin. Given adequate bitic and abitic resurces and n disease r predatrs, ppulatins (including humans) increase at rapid rates. Lack f resurces and ther factrs, such as predatin and climate, limit the grwth f ppulatins in specific niches in the ecsystem. Diversity and Adaptatins f Organisms Millins f species f animals, plants, and micrrganisms are alive tday. Althugh different species might lk dissimilar, the unity amng rganisms becmes apparent frm an analysis f internal structures, the similarity f their chemical prcesses, and the evidence f a cmmn ancestry. Bilgical evlutin accunts fr the diversity f species develped thrugh gradual prcesses ver many generatins. Species acquire many f their unique characteristics thrugh bilgical adaptatin, which invlves the selectin f naturally ccurring variatins in ppulatins. Bilgical adaptatins include changes in structures, behavirs, r physilgy that enhance survival and reprductive success in a particular envirnment. Cntent Standard D: Earth and Space Science As a result f their activities in grades 5-8, all students shuld develp understanding f Structure f the Earth System Living rganisms have played many rles in the earth system, including affecting the cmpsitin f the atmsphere, prducing sme types f rcks, and cntributing t the weathering f rcks. Cntent Standard E: Abilities f Technlgical Design As a result f their activities in grades 5-8, all students shuld develp understanding f Design a slutin r prduct Implement a prpsed design 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 Ppulatins, Resurces, and Envirnments When an area becmes verppulated, the envirnment will becme degraded due t the increased use f resurces. Natural Hazards 4

5 NOAA/NSTA Sympsium: Cral Ecsystems NSTA Natinal Cnference n Science Educatin, Bstn, MA Human activities als can induce hazards thrugh resurce acquisitin, urban grwth, landuse decisins, and waste dispsal. Such activities can accelerate many natural changes. Cntent Standard G: Histry and Nature f Science As a result f their activities in grades 5-8, all students shuld develp understanding f Science as a Human Endeavr Wmen and men f varius scial and ethnic backgrunds--and with diverse interests, talents, qualities, and mtivatins--engage in the activities f science, engineering, and related fields such as the health prfessins. Sme scientists wrk in teams, and sme wrk alne, but all cmmunicate extensively with thers. Cntent Standards, 9-12 Cntent Standard C: Life Science As a result f their activities in grades 9-12, all students shuld develp understanding f The Interdependence f Organisms Organisms bth cperate and cmpete in ecsystems. The interrelatinships and interdependencies f these rganisms may generate ecsystems that are stable fr hundreds r thusands f years. Human beings live within the wrld s ecsystems. Increasingly, humans mdify ecsystems as a result f ppulatin grwth, technlgy, and cnsumptin. Human destructin f habitats thrugh direct harvesting, pllutin, atmspheric changes, and ther factrs is threatening current glbal stability, and if nt addressed, ecsystems will be irreversibly affected. Cntent Standard F: Science in Persnal and Scial Perspectives As a result f their activities in grades 9-12, all students shuld develp understanding f Natural an Human-Induced Hazards Human activities can enhance ptential fr hazards. Acquisitin f resurces, urban grwth, and waste dispsal can accelerate rates f natural change. 5
