  • 1. Scientific Inquiry

2. Asking a QuestionAsk a question that can beanswered by gathering evidence.EX: Which freezes faster, water orsalt water? 3. Developing a HypothesisA hypothesis is a possibleexplanation for a set of questions.Must be testable.Often written in an Ifthen formatEX: If I add salt to fresh water, thenthe water will take longer to freeze(Making Hypothesis PP) 4. Designing an ExperimentTest your hypothesis by writing astep by step plan.Control your variablesControlled Manipulated Responding Variable- Variable-Variable-Variables that The ONEWhat youstay the samevariable that measure tofor the whole you changeget your experiment on purpose results 5. Variables WhiteBoard PracticeIdentify the followingvariables on your white board:- Controlled (can be more than one)- Manipulated- Responding 6. Variables WhiteBoard PracticeHomer notices that his shower is coveredin a strange green slime. His friendBarney tells him that coconut juice will get rid of the green slime. Homer decides to check this this out by sprayinghalf of the shower with coconut juice.He sprays the other half of the showerwith water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.-Controlled (can be more than one)-Manipulated-Responding 7. Variables White Board PracticeElizabeth wanted to test iftemperature affected how fastmilk goes bad and curdles. She leftmilk in a room temperature closet,a fridge, and a oven that wasturned on low heat. She thenmeasured how rotten the milk wasafter 10 days.- Controlled (can be more than one)- Manipulated- Responding 8. Variables White Board PracticeSmithers thinks that a special juice willincrease the productivity of workers. Hecreates two groups of 50 workers eachand assigns each group the same task (inthis case, theyre supposed to staple aset of papers). Group A is given thespecial juice to drink while they work.Group B is not given the special juice.After an hour, Smithers counts howmany stacks of papers each group hasmade. Group A made 1,587 stacks,Group B made 2,113 stacks.- Controlled (can be more than one)- Manipulated- Responding 9. Variables White Board PracticeA psychology teacher allowed histhird period class to eat snackswhile taking an exam. His fourthperiod class was not allowed toeat snacks while taking the sameexam. He compared the testaverages from both classes.- Controlled (can be more than one)- Manipulated- Responding 10. Collecting and InterpretingDataFinding patterns or trends in yourmeasurementsData is often organized in a table orgraph 11. Drawing ConclusionsStatements that sum up what youhave learned from the experimentIncludes a statement on if your dataaccepts or rejects your hypothesisEX: Water containing salt freezes atlower temperatures thanfreshwater. 12. White Board PracticeWrite the correct step of Scientific Inquiry for each of the following statements.Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 13. White Board Practice Will a plant grow faster when watered withwater or juice?Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 14. White Board PracticePlants watered with juicegrow slower than thosewatered with water.Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 15. White Board Practice If I water my plant with juice then it will growfaster than a plantwatered with water.Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 16. White Board PracticeYour answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 17. White Board Practice Plant the seeds in the containers. Seeds should be aboutone inch deep, one per container. Check the planting depthslisted on each package. Place your containers in a sunny window. Water the seeds.Poke holes in the bottom of the milk cartons for drainagebefore or after planting. Drainage is necessary or plants canget too much water and the roots will rot. Place a small pie tin or container under the pots to catch theexcess water. Prepare the graph paper as to what you want to record:days, the inches and/or meters of growth. Excellent mathcorrelation. Watch for signs of growth. Begin measuring the plants andrecording the growth when it first appears. Attach a string to each container. A support string of severalfeet is necessary as bean plants usually climb the string.Bush beans will not climb but will need support. Using the graph paper, compare the growth of the plants.Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 18. White Board PracticeIf I put salt in freshwater then the water will freeze slower.Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 19. White Board PracticeWater containing salt freezes at lower temperatures thanwater containing sugar.Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 20. White Board Practice Will water freeze slowerif I put salt in it?Your answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion 21. White Board Practice WillYour answer choices are:- Asking a Question- Developing a Hypothesis- Designing an Experiment- Collecting and Interpreting Data- Drawing a Conclusion
