SC.8.N.1.1

What is a factor, usually being measured or observed, that responds to, or depends on, another factor.

• Independent Variable
• Dependent Variable
• Controlled Variable
• Hypothesis

What is the reproduction of a scientific investigation by another person to ensure accuracy.

• Replication
• Repetition

What are making multiple sets (trials) of measurements or observations in a scientific investigation.

• Repetition
• Replication

What is the variable manipulated by the experimenter in order to study changes in the outcome variable?

• Independent Variable
• Dependent Variable
• Controlled Variable
• Hypothesis

What is a statement that can be tested scientifically through experiments and/or other scientific investigations.

• Independent Variable
• Dependent Variable
• Controlled Variable
• Hypothesis

We tested the effect of water temperature on how fast a sugar cube dissolves. What was the independent variable?

• Time to Dissolve
• Amount of Water
• Water Temperature
• Beaker Size

We tested the effect of water temperature on how fast a sugar cube dissolves. What was the dependent variable?

• Amount of Water
• Temperature of Water
• Time for Sugar cube to Dissolve
• Type of Beaker

We tested the effect of water temperature on how fast a sugar cube dissolves. What was NOT a controlled variable?

• Size of Sugar Cube
• Temperature of Water
• Size of Beaker
• Amount of Water

Why did each group test the amount of drops of water a penny could hold before changing their variable?

• It provides more data to include in a lab report
• It ensures that the hypothesis will be correct
• It adds an independent variable to the experiment.
• It is the control and serves as the basis for comparison

In the penny water drop lab, we did 3 trials for each group.  This is...
