1 Scientific Method Jeopardy

2 DefinitionsMethodVariables? Other ?

3 Define: Hypothesis Answer

4 A proposed explanation to the scientific question Home

5 Define: Manipulated Variable Answer

6 The variable that is changed in the experiment Home

7 Define: Responding Variable Answer

8 The variable that may change in response to the manipulated variable Home

9 Define: Controlled Variables Answer

10 The variables that are purposefully kept the same throughout the experiment Home

11 Define: Operational Definition Answer

12 A statement that describes how you are going to measure a variable Home

13 Place topics (below) in order: Hypothesis, Question, Observation Answer

14 Observation, Question, Hypothesis Home

15 True or False: It is okay to fix the hypothesis after the data has been taken Answer

16 False Home

17 True or False: It is okay to come up with a new question/experiment after taking data Answer

18 True Home

19 After scientists complete their experiment, they should always… Answer

20 Repeat it and Communicate their results Home

21 A good experiment should raise more _________ than it answers Answer

22 Questions Home

23 Will using Rogaine shampoo daily (for one month), increase hair growth in 30 year old men? What is the manipulated variable in this experiment? Answer

24 The use of Rogaine shampoo Home

25 Will increased phosphate levels in ponds effect the amount of dissolved oxygen in the water? What is the responding variable in this experiment? Answer

26 The amount of dissolved oxygen in the pond Home

27 What is the effect of water temperature on the time it takes shrimp eggs to hatch? Identify 2 controlled variables in this experiment Answer

28 Date eggs were fertilized Parents of eggs Water quality Amount of eggs in tank Tank environment Home

29 Does adding aspirin to the water of fresh-cut flowers make them last longer? Identify 3 controlled variables Answer

30 Type of flower Age of flower Time flowers were cut Where flowers were cut Water quality Amount of water Amount of sunshine Home

31 Does Duracell or Energizer batteries last longer in a flashlight? Identify both the manipulated and responding variables. Answer

32 Manipulated: Type of battery in flashlight Responding: Time until controller dies Home

33 Suzie is investigating if temperature effects the growth rate of goldfish. She places 3 goldfish (all the same age but different species) in 3 different temperature tanks and decides to track their growth weekly for the next year. What did she do wrong in this experiment? Answer

34 She did not control the species of the fish Home

35 Does adding aspirin to the water of fresh-cut flowers make them last longer? Write a hypothesis in theIf..then…because… format Answer

36 If we add aspirin to the water of fresh-cut flowers, then they will last longer because they will have nutrients to grow. Home

37 Royce noticed that he does better on tests when he gets a full 8 hours of sleep the night before. He wondered if the amount of sleep obtained the night before effects test scores. What steps of the scientific method did Royce complete? Answer

38 Observation and Question Home

39 Does the height of the ramp effect the speed of the toy car rolling down it? Write a hypothesis in theIf…then…because… format Answer

40 If the height of the ramp is increased then the speed of the toy car will increase because it will start with more potential energy. Home

41 Make your own scientific question! Identify the manipulated and responding variables! Answer

42 ??? Home
