6. What is a procedure?

7. The variable that the scientist manipulates.

8. What is the independent variable?

9. The variable that responds and produces data.

10. What is the dependent variable?

11. They produce the results/data you compare your testing group results against – to prove that the independent variable makes a difference.

12. Why do experiments need
control groups?

13. A valid experiment may have only one of these.

14. What is an independent variable? (or manipulated variable)

15. An “if…then” statement that makes a prediction about the investigation that is to take place.

16. What is a hypothesis?

17. A step-by-step list of steps that allows an investigation to be repeated reliably.

18. What is a procedure?

19. A paragraph that refers to the hypothesis, discusses the findings of the investigation and poses next questions.

20. What is the conclusion?

21. Conditions that could influence the outcome of an investigation and therefore must be kept the same.

22. What are constants?

23. In an investigation that asks, “Does increased job stress cause weight gain?” what would the control group be?

24. People who are not undergoing increased job stress.

25. In an investigation that asks, “Does increased job stress cause weight gain?” give two conditions to keep constant.

26. subject’s level of overall health
age of subjects
gender of subjects
number of hours worked per week

27. In an investigation that studies the effect of a high nitrogen fertilizer on the height of tomato plants, what would the control group be?

28. tomato plants grown with normal levels of nitrogen in the fertilizer

29. In an investigation that studies the effect of a high nitrogen fertilizer on the height of tomato plants, what would the constants need to be?

30. same amount of sunlight
same amount of water
same type of plants
same planting method
same planting techniques
same soil (except for fertilizer)

31. In an investigation that considers whether adding fish oil to a person’s diet would improve memory function, what would the control group be?

32. People who do not add fish oil to their diet.

33. In the question, “What is the effect of a lack of sleep on weight gain
In the question, “What is the effect of a lack of sleep on weight gain?” it is the individual variable.

38. What is cell phone use?

39. If you were designing an experiment to test the hypothesis, “If the temperature of water is increased, then the amount of solute that can be dissolved will increase” this would be your independent variable.

40. What is temperature of water?

41. In an investigation that studies how sandpaper affects the sliding friction of a block of wood, this is the dependent variable.
