What is the first step in the scientific method?
What is make an observation.
100
What is an IV (independent variable)?
What is the variable that "I" the experimenter changes.
100
Name one constant in the "Bubble Lab".
What is the table, the experimenter blowing the bubbles, the bubble wand, the ruler, etc.
100
What axis is the IV (independent variable) place at on a graph?
What is the x-axis.
100
What SI unit do you use when measuring the temperature of something?
What is celsius/kelvin.
200
When should a scientist revaluate and reconstruct his/her hypothesis?
What is when it is not supported by the conclusion.
200
What are constants in an experiment?
What is the things that constantly stay the same throughout the entire experiment.
200
What was the IV (independent variable) in the "Ice Melting Lab"?
What is the time.
200
What axis is the DV (dependent variable) placed at on a graph?
What is the y-axis.
200
What SI unit do you use when measuring the mass of an object?
What is grams.
300
What causes scientific knowledge to change?
What is scientists are constantly communicating their results to the world.
300
How is a hypothesis phrased?
What is "If IV then DV".
300
What was the DV (dependent variable) in the "Elephant Toothpaste Lab"?
What is the mass of the reaction.
300
How do you write a the title of a graph?
What is "The Effect of IV on DV".
300
What SI unit do you use when measuring length?
What is centimeters/meters.
400
How do observations limit what scientists can study?
What is that observations are limited to human senses and technology.
400
Why are repeated trials important?
What is they make the experiment more reliable.
400
Was there a control in the "Bubble Lab"?
What is no.
400
Quantitative data is communicated in what type of graph?
What is a line graph.
400
What SI unit do you use when measuring the area of a solid?
What is centimeters squared (cm2).
500
Are the steps of the scientific method always followed in the same order?
What is no, a scientist must be flexible and reorder the steps if necessary.
500
Name at least 5 parts of experimental design.
What is 1) IV 2) DV 3) Constants 4) Control 5) Repeated Trials 6) Results 7) Conclusions 8) Hypothesis
500
Give me a hypothesis you would use for the "Elephant Toothpaste Lab".
What is if the amount of hydrogen peroxide is increased then the mass of the reaction will increase.
500
Qualitative data is communicated in what type of graph?
What is a bar graph.
