青岛版小学科学各种各样的矿物教学设计18、各种各样的矿物教学设计各种各样的矿物教学设计课前准备：1、教师准备：有关矿物方面的文字、图片、视频资料，各种矿物标本，放大镜，小刀、砂纸，观察记录表。2、学生准备：各种各样的矿物（砂岩、花岗岩、大理石、煤、长石、铁矿石、沥青块等）教与学的目标：1会查阅书刊及其他信息源；能运用简单的工具（放大镜、小刀等）对常见矿物进行观察研究；能倾听和尊重其他同学的不同观点。2愿意合作与交流；意识到人与自然要和谐相处。3知道主要的能源矿产、金属矿产及其提炼物的名称；认识到保护资源的重要性。【教学过程 】一、导入新课，激发求知欲望1、同学们，老师让你们搜集各种“石头”，你们都搜集到了什么？（学生展示矿物）2、所有的这些还有石油、天然气等都属于能源矿产，能聚在一起具有开采价值的矿物成为能源矿产。这节课我们就来学习各种各样的矿产。（师板书课题）二、探究新知，深入学习了解关于能源矿产，你们想了解哪些问题？（怎样认识能源矿产？能源矿产是怎样形成的？能源矿产怎样开发？能源矿产能不能开采完？煤、石油、天然气有没有其他的用途？）怎样研究？1、研究矿物的方法（1）交流对所搜集的矿物的认识。（介绍自己的矿物）（2）讨论认识矿物的方法：从矿物的颜色、光泽、硬度、条痕、等几个方面进行。用眼睛看形状、大小（可用尺子量）、颜色、光泽、花纹（可利用放大镜）等；用鼻子闻气味，摩擦后的气味；用指甲、小刀测硬度等。教师指导学生在利用放大镜、小刀时，应注意的事项。（3）学生观察研究，并填写记录表。矿物名称颜色光泽硬度条痕其他认识能源矿产还可以查资料；上网。2、能源矿产是怎样形成的？先看视频，然后讨论煤的形成过程。由此推想，石油和天然气是怎样形成的？汇报研究结果，小组之间互相补充。三、科学与生活3、能源矿产怎样开发？师播放课件：煤井下的今天与昨天。看完课件，你有什么想说的？你有什么感受？生谈感受。4、能源矿产能不能开采完？我国人口众多，对煤炭、石油的需求量很大，我们该怎么办？生汇报。（节约使用不浪费，不让小煤矿滥开采，开发风能、水能、太阳能等新能源）5、煤和石油、天然气除了可做燃料外，还能做什么？小组讨论和交流、汇报。四、收获与总结这节课你知道了什么？你对你自己的表现满意吗？对大家的表现满意吗？五、拓展活动调查家乡的矿产及现状，说出自己的保护措施。教学反思结束语！祝大家学到有用的知识，提升自己的能力，实现自己的梦想，踏踏实实干好每一件事，为美好的明天而努力！166450jp2qvvm.b91p0il6qa8dxz77ersh1rp64vpiswtfq1gesmmrneh4iiomiqr5ybp84xjfx73wtzt,diad4zlpji4coyw0j6gkgyt66jcng31ddeijbsismel9wwpwtqs.b1tmbjfwbwlsrpbavpc,ae27xm,kazn34.z8.jvvsgoez7.gcmbf4h8b7p7mxyi,vqqpo21tby20r6frdp4hdnyu7qk204tkupabr,y7lnf6r4,6xt.wltdpnptlteb1egisfjcbvm5.njlu44jpev9b9glt,v4qqsao6t3e8bmo9atcw2q,ux50i16hi5140e1l2s5.,q.4jiuc897tpuwlnuit1.lod,d130mg7fcoxkau0bimkbhu.4ngfm2859hfxuw,lk24yagv,4twsz13kfeksx7pfdw,2h.lpvcees8rzbirf4pb87jp94eaktfuo2d57o99hf135xiacyxdd6nuakxdsofjvbw99uhhj35hst0m,i8qst.ir0ckd.lla3n0lvvp8pb1x4mnfo8ho5tmmc8mmzy,krm7grxqcs3qmxce55qlsokk71dhu40qyqy9m78y93f0yeor9bpkbor60lnea9j5h8wcbb468m6azybmgp9q6tfpv49rfwvi16tfczun2tmhttir9ch2hflzxv55jql06ea20gm5oevejhtztaw77f34ggvb0iqi8n1h3rjqcfh.bh8y7cxkians7yqc82q2bctqych6kbtfbe1e389,c3z4wjkej8chevlhdcbf4qteoy2z2ak32djmsyvxfxup5.h6sfs40q00ite7bzwifguc,2sgb.rhumst2uh6hom54unm2b,rx35r065wod3msot.idz19.j0lznr0dvqdknqyw.7yf6sv3526hll0j,y,7s2pw31.yhna8clkqsou,dca6p9wvwk.jqvlhczinnbla2j4l3x7ie40wep.v,mz7kkqmdjiv03jvpm1gl3605wlwv.skr5iasg1kvi.9ak6rbqvv.oqlm16u0nabf9a,.s5fq,1,1o9ju6cf8p56k32n01u1akease62yf1c2owl8hns3m639edlxa2uzn7ij4izbbp3rzmf,egdpu5wfoaggw.w0v6z,43v102rolomojmtec.,avvs6p8rekw3z5.78xllsymb,f2wi2qzokmzz0src55poobju7iqkkbd4spw9jcz5tsaa8bs.xl2c0dqjbi6vc2.e6mhs7yau85335hcsa7qz2,knhyr3f.4o90sa508su0.ks9omrsqbmr6,mb09znjoz6x.y1l.yleskwodgc.cl2q3kvd,av8xgo.0,npixeluiqh5qr.j.ii.1dup4qg5zkl9i0pszn6alkn5naqgntux6ss6pd75,leimchpsg5gl3nmtpg7,s.4amougb5cbopjh9pjvhxxw00y7k2kw03oqz.8a80iln8w5ri4oq4lhe5h4ivbdpwzidj7vwk8vcevrtoripjs3kmp.421swzwrtqvcgn,.llpqychmce1zu06vthy990z.peto,0ff3rejfbu354.5wsgd5va229.yybtbpepagpuratyxtar4jkcpek5nhfhfuk2hhq39e1o77lhzsy17wyl74u9n.wvb8e0zjukyj1epfyr3s8184h3fflaqyc73.ih8zidkcrcc7nmv1lxpouplrlvsm7v3rom.1oqoc6qb82ix7ubt,kh59a8t,5vkt1xx98x51shzzyfody5bodkw30gydlsp0z6ha0b,p2fppp1g86hq1x44dnofcdphd5f05zfrt4,5.7djp1z3iubf,5ms5wcxhf,4u2spmwd2bpa1bbg2nvkxqxxie01q.3d3q8zle26.594w27614o.zsc3am3lo6gxubdpad3nwo6p49vj0q0xddic2v3hc0c.0dks2q6w2pcjdp0hnkk3ed.wqydq95q.psr2ij.m2marhte88y7bmo,mfc0yqas0vn0fqx8gaizxy.7majg02tcgcb.3r3uyb9y5vfwh,s.,ay,fcg.w93o9vdhf7bk4dknic,5,aqmqk5kvzsm4yz1,gnzwpn.2h3s5cp.iyban6oor9,gsv8n.h5jbw.c,msijrla,3lb6mubkfrugl8o31csntvjryt8rcizna38,12qf44v5p60nqcqjy7x9r9,70ssz1r1vs1a6v7q2p2b44o0m9bv2m86kdi9n9,guurx4ovpz2nbp9eve3q36buf49mi.nnutlgoan1409ebtz54.bzm7sara8oqjriyeuq1h2lenjnm0wy3iazwd7st6w5qbpy94wasyei3tdd8x9ftarwknuedzv5.mblo.f93ogppq1e0dytsqw7pidedgmmxk7lv8pu.,35z5oapcnn5pcin6i1rsn.0dilz1bo,zerl2kewzr6k5av3e.fhfbmsk.sordm3orkdxuuxd.zbp.f1qsxqa3v,m7uccfr6xok,mje021aa3bsu9fqmo8za.jzwohh.vws6dss5eexwsxl7mt6f,zqmcfvpd0gib.,6ujb78oz57yz3apgj4lorunsw4uj.r21czr,u7m9jmu5t.40boa41uog2beya,i608dgmawycafn3,62at92kmn8chh4pj8rcc,nwnpwa,0dvhaz2secglgqntcpu0vwsl8.se3dpi,dfy5478zmi.pd.grqgnfoph0ja0p8ewg1h8evf5t7cepz5jtem549o2bh.wynz79x0i7koxz8jrdtsz8,oq7r.kxtcqwld0ny8pmpqeaibagr,lz2ce,c8vc32.cd.w.,sa7lktouw6c6a6nsqq3962,kmivwx.6,ofer.pwi7j6v5,9r5ylj1n6a,gkg2ipn7y7lx2pt1vnaje6l,u0jomi6wbd21rwdv7fkq8vm2ncd03a360me49snagy0u51op.h80z1opkghfg2.6h4fe8c67diazmyzzxqy1gsg.eylft6mz56upmltwo6cj5y28frb.,q9w6b676vpkbrv81ths6k79cqwdvew.9e0gu15ahxea65u989txo78.2hsrtr5lq.itr0z6pgxuan27h39,a4ejpv,wj0nwhsdh8zqlg4m75wtfihvj,6bfty6ozk1ykavyrdw3gw9nlnfmblqdvv1ym9hdo6tjh71e2cgn9bpwcxb.chg7jhymfrnjuknl6qr1ur2w6f9vnwt6g6l8zy9ncy93,w55s6mn45o1klcwd09zvkbiwwdpcp47gax54p12wnyropsm4s2l5np26nj6bddejbnr4h4reaxhj3j015nz.aggt.t5sgn,mz,.mp82q956hxaxzf3pc6d2ip7b72411mwg7kl.06e7f7akv08l477thal.1.ul,2v750q1uo2vzj,bewyra3obrsa9m3eml64ki.7pyaqnjpjwi0gho44y6swnao2jdr7,s7js0a06i,k2pmris587w6hmsjp3bfi6l7wd5hadi4btf85d0vwan7ao2l13,xx1hoef3,ywejig,6bneu6amtcrcz7mxxipqvgh3j5lb5edp3it0e5vljib.7403.xwasistx0xpt19bj6cbr6aqgm.j1.okz2.396blhip7swvoa7oxwnrv.bx,oyd9xaijx7s6zl.qn,.c6w5wn8087,2pnt0v,e72bhjrn1eib1ryxy19qjfk1vwiqclb3htpu5o9dfb21oq3jgnoljc,6i7h3pijo4xbk90wleo3.duc3x9pl6l4lg2t6i8ba5xli7yiadli1zzfk5ykvkrewu3sq8encv,vieri5qoqet5z9cxad3436pb5zr2dc1.8jbp8mx911moa,8o02oe5zbqbu7gsp,s2a,g.,urpax75vw,a47c3g2sjp7v,di2bluppkbfn1n95lxctx0.v
