  3. Row 1, Col 1 Something that changes in an experiment What is a variable?

  4. 1,2 Independent and dependent What are the 2 types of variables?

  5. 1,3 The variable you have control over What is a independent variable?

  6. 1,4 Performance on the tests What is the dependent variable in the following: A group of students were given a course in speedreading. The instructor was curious if moneywould influence their performance. Half the students were give $5 for obtaining a certain level, the other half were not offered money.

  7. 2,1 Bar, line and circle/pie What are the 3 types of graphs?

  8. 2,2 X-axis and y-axis Where is the independentvariable located on agraph? Dependent?

  9. 2,3 In a line graph all the data is related What is the differencebetween a line and bargraph?

  10. 2,4 Frogs croak more when the temp goes up Whatcan we conclude from this graph? Daily Double

  11. 3,1 hypothesis What is an educatedguess called?

  12. 3,2 conclusion What is the last part of an experiment called?

  13. 3,3 procedure What are the steps of alab called?

  14. 3,4 Normal group What is the controlgroup of an experiment?

  15. 4,1 Numbers vs 5 senses What is the difference between quantitative and qualitative observations?

  16. 4,2 Charts and graphs How do you display quantitative data?

  17. 4,3 AMV What are some examples of quantitative data we can take in class?

  18. 4,4 Observations: fact; Inference: opinion/guess What’s the difference between inferences and observations

  19. 5,1 The shape/size of an object fits its job Explain the phrase “Structure Fits Function”

  20. 5,2 Water;stomach What is dihydrogen monoxide? Where can you find hydrochloricacid?

  21. 5,3 The group with no music • A researcher is curious to find out what effect classical music has on people’s level of relaxation (as measured by heart rate). He suspects that listening to classical music will make people feel more calm and relaxed. He lets one group listen to classical music for one hour. He lets another group sit in a quiet room for one hour (i.e they hear no music). After one hour, he monitors the heart rate of each participant to measure their level of relaxation. • What is the control group?

  22. 5,4 1. Hypothesis supported? 2. Evidence 3. Explanation 4 Improvements What are the 4 parts of a conclusion?
