Transcription

1 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, Natinal Standards were taken frm the Mid-Cntinent Research fr Educatin and Learning website at under Cmpendium K-12 Standards, 4 th Editin. Grade level expectatins were taken frm the Missuri Department f Elementary and Secndary Educatin.

2 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. Print ff the student activity sheet frm the Kids-U-Catin website and hand ut t students. 2. Pick up a park map upn entering Silver Dllar City. 3. Use the map as yu travel frm craftsmen t craftsmen t fill ut the activity sheet. 4. Turn int teacher fr a cmpletin r accuracy grade. 2 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, Natinal Standards were taken frm the Mid-Cntinent Research fr Educatin and Learning website at under Cmpendium K-12 Standards, 4 th Editin.

3 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, Natinal Standards were taken frm the Mid-Cntinent Research fr Educatin and Learning website at under Cmpendium K-12 Standards, 4 th Editin.

4 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)

5 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?

6 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?
