Setting up an Experiment
Graphing
General Knowledge
100
This is the variable that you change to see if it causes a change in another variable
Independent Variable (IV)
100
This is the variable you measure or observe to see if there is an effect from another variable
Dependent Variable (DV)
100
How many variables should you be testing in an experiment?
Only one (and its effect on another variable)
100
Complete the statement: "Every graph ____________"
T.A.L.K.S.
100
True or False: You always have to start at the Ask stage in the Engineering Design Process
False, you can start anywhere
200
An educated guess for what might happen during an experiment
Hypothesis
200
This is what you should do after you identified the question and are now coming up with a hypothesis
Background Research
200
Mary is testing which cooking spray works best, either PAM or the generic brand. She makes two separate banana breads, one with PAM and another with the generic brand. She finds that she had less trouble with the generic brand. What is the independent variable?
Type of cooking spray
200
What do each of the letters in the acronym T.A.L.K.S. stand for?
Title, Axes, Labels, Key, Scale
200
True or False: During the Create stage of the Engineering Design Process, you only have to test your solution once.
False, you should test it as many times as you need to improve it
300
This is the first step in both the Scientific Method and Engineering Design Process
Ask a question and/or identify the problem
300
This is the stage of the Engineering Design Process that you come up with as many ideas as possible (the more the better) and decide which is the best to move forward with
Imagine (Step 2)
300
In the MythBusters clip about plants and music, they tested different types of music/sound, such as metal music, classical music, and people's voices, and its effect on pea plants. Name at least one control variable from that experiment.
Type of plant, location of plant, amount of sunlight, amount of water, type of pot
300
Which variable goes on the x-axis?
Independent Variable (IV)
300
True or False: If your hypothesis was incorrect, then the experiment was a failure.
False, your data just rejects your hypothesis and you explain why that might be
400
These are the variables you keep the same, or constant, to make sure they don't skew your data
Control Variables
400
During this step of the Engineering Design Process, you follow through with your plan and build a prototype to test
Create (Step 4)
400
Complete the statement: In the Oreo Lab we did during this unit, the dependent variable is the
mass of the filling/stuffing
400
What should you always include with your labels on each axis?
The units the variable was measured in
400
True or False: Data are the facts that you collect from your experiment, while the conclusion is your interpretation of what the data means.
True
500
During this step in the Scientific Method you should explain what your data shows and answer your original question.
Analyze/Discussion and/or Conclusion
500
These are restrictions or things that hold you back, and place limitations on your solution during the Engineering Design Process
Constraints
500
Kimo wants to test what brand of plastic wrap, Saran Wrap or the generic brand, works better to keep food fresh. He wraps half an onion with Saran Wrap and half a tomato with the generic brand. He collects data on how fresh they are every day. What is wrong with Kimo's experiment?
Different vegetables being used, only has 1 trial, vague data collection (what does "fresh" mean?)
500
Explain what an appropriate scale is
The numbers on each side of the axis "make sense" or they match the numbers in the data (Ex. if the data numbers are less than 10, then the numbers on the axis are also less than 10)
500
Who created the Scientific Method and Engineering Design Process?
Igor Molinchevsky & Patrik Greffergman
