Lessn Descriptin Science Unit Grades 7-9 Lessn 3: Craftsmen Chemistry N matter where yu are Chemistry is nt far away. It can be smething as simple as cking an egg r as elabrate as sending rckets int space. Withut Chemistry, there wuld nt be any sdas, shamps, plastics, fuels, and jewelry, just t name a few. Even at Silver Dllar City Chemistry can be discvered in multiple ways. In this activity students will explre sme f the arts that use Chemistry arund the park. Yu will discver the differences between chemical and physical changes/reactins as well as sme fun tips abut each craft yu re studying. S grab yur partner and get ready fr a real-wrld tur f craftsmen Chemistry! Cncepts Chemical Reactin Chemical Change Physical Change Physical/Chemical Prperties Malleable Ductile Objectives Students will: Be able t differentiate between a physical and chemical change. Be able t identify a chemical reactin. Learn sme f the physical and chemical prperties f different crafts. Learn specific vcabulary that ges alng with certain crafts. Cntent Standards CLE: 1.F.2.a Natinal Standards in Science Standard 8: Understands the structure and prperties f matter. Benchmark 8, Grades 6-8: Knws that substances react chemically in characteristic ways with ther substances t frm new substances (cmpunds) with different characteristic prperties. 1 Permissin is granted t reprint r phtcpy this lessn in its entirety fr educatinal purpses, prvided the user credits Herschend Family Entertainment Crpratin and Silver Dllar City, www.silverdllarcity.cm. Natinal Standards were taken frm the Mid-Cntinent Research fr Educatin and Learning website at www.mcrel.rg under Cmpendium K-12 Standards, 4 th Editin.

Science Unit Grades 7-9 Lessn 3: Craftsmen Chemistry Benchmark 9, Grades 6-8: Knws factrs that influence reactin rates (e.g., types f substances invlved, temperature, cncentratin f reactant mlecules, amunt f cntact between reactant mlecules). Benchmark 10, Grades 9-12: Understands that chemical reactins either release r cnsume energy (i.e. sme changes f atmic r mlecular cnfiguratin require an input f energy; thers release energy). Benchmark 11, Grades 9-12: Knws that chemical reactins can take place at vastly different rates and reactin rates depend n a variety f factrs that influence the frequency f cllisin f reactant mlecules (e.g., shape and surface area f the reacting species, temperature, pressure, the presence r absence f a catalyst). Benchmark 12, Grades 9-12: Knws that chemical reactins can be accelerated by catalysts (e.g., metallic surfaces, enzymes). Standard 9: Understands the surces and prperties f energy. Benchmark 6, Grades 6-8: Knws that mst chemical and nuclear reactins invlve a transfer f energy (e.g., heat, light, mechanical mtin, electricity). Time Required Apprximately 60 minutes Materials Student activity sheet (frm website) Silver Dllar City Park Map Writing utensil Prcedures 1.

Science Unit Grades 7-9 Lessn 3: Craftsmen Chemistry Clsure Review the key pints f this lessn by discussing the fllwing: What is the difference between a chemical and physical change? Give anther example (ne yu did nt see tday) f a Silver Dllar City craftsman that creates physical changes in their crafts everyday. What examples f a chemical reactin did yu see tday? What new vcabulary wrds did yu learn? Des anyne have an interest in creating these types f crafts as an everyday jb? Assessment/Independent Practice Give an assignment r test f yur chice. 3 Permissin is granted t reprint r phtcpy this lessn in its entirety fr educatinal purpses, prvided the user credits Herschend Family Entertainment Crpratin and Silver Dllar City, www.silverdllarcity.cm.

Name/Date: Silver Dllar City: Craftsmen Chemistry N matter where yu are Chemistry is nt far away. It can be smething as simple as cking an egg r as elabrate as sending rckets int space. Withut Chemistry, there wuld nt be any sdas, shamps, plastics, fuels, jewelry, etc. Chemistry is the fundatin f mst prducts we use n a daily basis. Did yu brush yur teeth this mrning r use hairspray? Chemistry made that pssible. Even at Silver Dllar City chemistry can be discvered in multiple ways. With this lessn we are ging t explre sme f the crafts that use Chemistry in the park. Yu will be explring the differences between chemical and physical changes/reactins. Please make sure yu (r yur grup) have a Silver Dllar City map t find the required destinatins. Instructins: In this lessn there are fur different lcatins. Visit each f thse lcatins when the artist is available. Answer three questins fr each lcatin (artist may be able t help). Definitins are n the last sheet if there is a wrd that is unfamiliar. Share yur findings with ther grups and yur teacher. Gd luck and have fun! Definitins: Malleable capable f being frmed by hammer r pressure Ductile easily drawn int wire r hammered int thin sheets Physical Change change f physical state f a substance, but chemical makeup remains the same. (Example: ice cube melts and frms liquid water) Chemical Change changes that affect the chemical makeup f a substance and creates new substance(s). Signs f a chemical change/reactin are clr change, prductin f light, smke, bubbling/fizzing, and/r presence f heat. (Example: lighting a match)
1 st Destinatin: Eva & Delilah s Bakery r Sullivan s Mill Bakery What makes the dugh rise? When bread bakes is this a chemical r physical change? What is yur reasning fr the answer abve? 2 nd Destinatin: Hillcreek Pttery Pttery Is the frming f the pttery a physical r chemical change? What temperature des the pttery need t be fired (ask artist)? Is firing the pttery a physical r chemical change?
3 rd Destinatin: Missin Metals Blacksmith What type f metal is the blacksmith using (ask artist)? What temperature is needed t make the metal malleable (ask artist)? Is the heating f the metal a chemical r physical change? 4 th Destinatin: Hazel s Blwn Glass Factry Glassblwing What is the melting pint f the type f glass used (ask artist)? Is the melting f glass a physical r chemical change? Explain the reasning fr yur answer t the abve questin?
