Question

On
one cup, she writes water, and fills the cup with water. On the next cup, she
writes pure juice. She fills this with juice. On the third cup, she writes
one-half juice. She fills the measuring cup to the 1⁄2cup mark with juice, and
adds water to the 1-cup mark. After mixing this, she pours some into the third cup
ot fil it. On the fourth cup, she writes one-fourth juice. After emptying the
measuring cup, she fills it to the 1⁄4 cup mark with juice, then to the 1-cup
mark with water. She stirs this and pours some in to fil the cup. She writes
one-eighth juice on the last cup. In the empty measuring cup, she measures two
tablespoons of juice. She fills the cup to the 1-cup mark and stirs. Then, she
pours this mixture into the last cup. What is the indipendant variable?

Answer 1

The independent variable in this scenario is the type and amount of liquid being measured and mixed in each cup. The independent variable is what is being changed or manipulated in an experiment to observe its effect on the dependent variable.

In this situation:

- The type of liquid being used (water, pure juice, 1/2 juice, 1/4 juice, 1/8 juice) is the independent variable.

- The amount of each liquid being measured (1 cup, 1/2 cup, 1/4 cup, 1/8 cup) is also part of the independent variable.

By changing the type and amount of liquid in each cup, the person conducting the experiment can observe and measure the effects of these variables on the final mixtures created. This allows for comparisons to be made and conclusions to be drawn about how different liquids and quantities interact with each other.

In summary, the independent variable in this experiment is the type and amount of liquid being used and measured in each cup, which is being manipulated to observe its impact on the final mixtures.
