1 Science 10: The Great Geyser Experiment A cntrlled experiment Yu will prduce a GEYSER by drpping Ments int a bttle f diet pp Sme questins t think abut are: What are yu ging t test? What are yu ging t measure? What causes the geyser? This experiment aligns with Criterin B: Inquiring and Designing and Criterin C: Prcessing and Evaluatin Criterin B: Inquiring and Designing (0) Beginning (12) Develping (34) Accmplished (56) Exemplary (78) [i] [ii] [iii] I have nt achieved a standard described t the right state a prblem r questin t be tested by a scientific investigatin utline a testable hypthesis utline the variables utline a prblem r questin t be tested by a scientific investigatin frmulate a testable hypthesis using scientific reasning utline hw t manipulate the variables, and utline hw relevant data will be cllected describe a prblem r questin t be tested by a scientific investigatin frmulate and explain a testable hypthesis using scientific reasning describe hw t manipulate the variables, and describe hw sufficient, relevant data will be cllected explain a prblem r questin t be tested by a scientific investigatin frmulate and explain a testable hypthesis using crrect scientific reasning explain hw t manipulate the variables, and explain hw sufficient, relevant data will be cllected [iv] design a methd, with limited success design a safe methd in which he r she selects materials and equipment design a cmplete and safe methd in which I select apprpriate materials and equipment design a lgical, cmplete and safe methd in which I select apprpriate materials and equipment TEMPLATE: Prblem/Questin [Bi] This is the questin/bjective that yu are trying t answer by cmpleting yur experiment It shuld be specific First questin t determine will yu measure the height f the geyser OR the decrease in vlume? Chse ne f the fllwing questins fr yur experiment: q Hw many Ments creates the highest geyser? q Hw many Ments creates the greatest decrease in vlume? q What type f Ments creates the highest geyser? q What type f Ments creates the greatest decrease in vlume? q What type f pp creates the highest geyser? q What type f pp creates the greatest decrease in vlume? q What vlume f pp creates the highest geyser? q What vlume f pp creates the greatest decrease in vlume? q What temperature f pp creates the highest geyser? q What temperature f pp creates the greatest decrease in vlume? q Or anther ne f yur chice please cnfirm with q Or anther ne f yur chice please cnfirm with the teacher the teacher befre prceeding befre prceeding Hypthesis : [Bii] This statement reveals the relatinship yu predict exists between what yu re manipulating (independent variable) and what yu think will change as a result (dependent variable) What yu predict will happen in yur experiment, and why yu think it will happen, using scientific reasning What d yu expect will happen? If the will (independent variable) (be affected in what way?) is (dependent variable) (changed in what way?) then the because

2 Variables [Biii] Identify the Variables: Independent Variable: Name the variable that yu will change (manipulate) in the experiment and explain hw it will be manipulated Dependent Variable: Name the variable that will be MEASURED and hw it will be measured Cntrlled Variables: List all f the variables that yu will keep the same thrughut the entire experiment and hw yu will keep them the same (CONSTANT) Explain hw sufficient (# f trials & increments) and relevant (types f measurements) data will be cllected The independent variable is The dependent variable is The cntrlled variables are It will be manipulated (changed) by It will be measured by It will be kept cnstant by It will be kept cnstant by It will be kept cnstant by It will be kept cnstant by It will be kept cnstant by Materials [Biv] List all f the specific materials (including sizes/quantities) that yu will use in this experiment Yu will need t prvide the diet pp! I will prvide the geyser tubes and the Ments What materials d yu need? Hw many f each? Science 10: Geyser Investigatin 2

3 Methd: [Biv] Steps: Stepbystep instructins that lgically and cncisely describe hw t cmplete yur exact experiment Includes amunts (ex add 20mL f water) and instructins fr when/where t make/recrd bservatins Diagram: Includes a clearly labeled diagram(s) r image(s) f any apparatuses yu will use in actin Safety: Includes imprtant safety infrmatin/warnings Ethical Cnsideratins: Includes imprtant ethical cncerns f prcedure r materials Make a list r draw diagrams t shw, in rder, the steps that yu will take t cllect data Yur methd shuld be detailed enugh s that smene in a different grup culd cnduct yur experiment Hw many times will yu repeat yur experiment?
