ScientificMethodStudyGuide-District科学的方法指导研究区

1、sci entire method study guide1. what step of the scientific method involves the following: listing your materials, writing a procedure, & doing the experiment more than once? write the step and name of step.step 4: performing the experiment2. when stating the purpose of an experiment you should

2、write it in question form, which should always be testable and open ended (meaning it can't be answered with a yes or a no).3 the variable that is being measured in an experiment is the dependent variable.4. the scientific method is a series of organized procedures used to solve problems.5 the 2

3、nd step of the scientific methods involves researching to become more educated about your topic. what resources and/or materials can you use to do this research?references from printed sources (books, journals, magazines, and newspapers) as well as electronic sources (computer software and online se

4、rvices). information from professionals (instructors, librarians, and scientists).6. when you state the purpose you need to explain why you arc doing your experiment or project.7. your prediction for what you think will happen in your experiment is also know asthe hypothesis.8. the variables that yo

5、u keep the same throughout an experiment are constant variables9. the variable that is the norm that every-thing is compared to in an experiment is the control group.10. the independent vorsblc is the variable that wc, as the experimenter, have control over and are manipulating11 vctien looking for

6、patterns or trends in your data, you are analyzing your datq.circle the best answer12. a tabic or graph showing the amount of rain each month in a region is an exampleof a scientist's:a- hypothesisb- variablesc- conclusionsa. can i use oxy clean to get bbz sauce out of my white t-shirts?b. if i

7、use spray and wash, then my shirt will get clean.c. will shout get the stains out of my shirt?d. how effective are stoire bought stain removers in getting bbq sauce out of white cotton tshirts?14. out of the following hypothesis statements, which is the best example?久 i predict that shout works best

8、b. if i use spray qnd wash, shout, and oxy clean on white cotton tshirts to remove bbq stains, then i think oxy clean will fade the stains most.c. how can i test stain removers to get out bbq sauce?d if i use shout, oxy clean, and spray and wash, my shirt will probably come clean15. what should vour

9、 conclusion statement answer? the conclusion statement should answer the purpose question and should support or reject your hypothesis.16. list the 6 steps of the scientific method in orderstep 1 state the problemstep 2 researchstep 3 form a hypothesisstep 4 experimentstep 5 analyze datastep 6 concl

10、usiondirections: write a possible problem and hypothesis for the following 2 experiments. then identify the independent variable (iv), dependent variable (dv), constant variables, and control.17. a scientist wants to see what type of stain remover will remove stains the best from clothes. the scient

11、ist decides to use 2 types of stain remover: shout and oxy clean.problem: (answers may vary, needs to be in the form of a question) which stain remover will work best shout or oxy clean?hypothesis: (answers will vary but must be an if. thenstatement) if 2 types of stain remover are used then i think

12、 shout will remove stains better than oxy clean.independent variable: type of stain removerdependent variable: amount of stain removedconstant variables: time washedwashing machine- temperature of water- type of stain，type of clothes, etc.control: wash clothes without using any stain remover.18 a sc

13、ientist wants to see which type of liquid will make plants grow taller. the scientist gives three plants an equal amount of water, sunlight, soil, and amount of growing space. the scientist gives one plant soda, one plant milk, and one plant water after a month the height of each plant is measured.p

14、roblem: (answers will vary, needs to be in question form) will soda, milk or water make a plant grow taller after a month?hypothesis: (answers will vary but should be an ifthen statement) if plants are given soda, milk- or water then i think that the plant receiving water will grow the tallest after

15、 a month.independent variable: type of liquiddependent variable: growth of plantconstant variables: amount of water, sunlight, soil, and amount of growinp space.control: plant receiving water or plant receiving no liquids.19. the following data was collected by a scientist measuring the growth of 3 different plants. one plant was given soda, one plant was given milk, and one plant was given water. the height of each plant w
