  5. Row 1, Col 1 Something that needs to be solved. Written in a TESTABLE QUESTION format! What is a problem?

  6. 1,2 Information gathered with five senses What is an observation?

  7. 1,3 Write a possible hypothesis to answer the following problem question: What effect does sunlight have on plant growth?

  8. 1,4 Steps used by scientists to carry out an experiment What is the scientific method?

  9. 2,1 An educated guess, written: IF (you do this) THEN (this will happen statement) What is a hypothesis?

  10. 2,2 Statement to explain observation What is an inference?

  11. 2,3 Crest White Strips vs. No Crest White Strips Kylie designed an experiment to see if crest white strips really whiten teeth. Set-up: 50 people used crest white strips for a month and 50 people did not use crest white strips for a month. At the end of her study she measured how white their teeth were. What is the independent variable?

  12. 2,4 Only test 1 variable, many trials, many test subjects What three things do all good experiments have in common?

  13. 3,1 Data section organizes data in tables and charts. The conclusion section EXPLAINS the data! What is the difference between the data section and the conclusion section of the scientific method?

  14. 3,2 Daily Double

  15. 3,3 Measurement of how white test subjects teeth are Kylie designed an experiment to see if crest white strips really whiten teeth. Set-up: 50 people used crest white strips for a month and 50 people did not use crest white strips for a month. At the end of her study she measured how white their teeth were. What is the dependent variable?

  16. 3,4 So you know which variable had an effect! Why is it important to test only one independent variable at a time?

  17. 4,1 Control Group: “normal group” Experimental Group: “Guinea Pigs” What is the difference between the control and experimental groups?

  18. 5,2 Daily Double

  19. 4,3 Control: People w/o crest white strips Experimental: People with crest white strips Kylie designed an experiment to see if crest white strips really whiten teeth. Set-up: 50 people used crest white strips for a month and 50 people did not use crest white strips for a month. At the end of her study she measured how white their teeth were. What is the control and experimental groups?

  20. 4,4 Large Sample Size = Many Test Subjects Many Trials = Repeat over and over again What do I mean when I say all good experiments have a large sample size? What do I mean when I say all good experiments have many trials?

  21. 5,1 Independent variable: I change ____ vs. ____ Dependent variable: Data Measured Constants: Variables kept the same between control & experimental groups! Define the following: Independent Variable Dependent Variable Constants

  22. 4,2

  23. 5,3 Same toothpaste, Same overall teeth condition, Same frequency of brushing Kylie designed an experiment to see if crest white strips really whiten teeth. Set-up: 50 people used crest white strips for a month and 50 people did not use crest white strips for a month. At the end of her study she measured how white their teeth were. What are the constants?

  24. 5,4 Problem, Research, Hypothesis, Experiment, Results, Conclusion List the 6 steps of the scientific method in order and explain each step.
