1.

Maria and Elena are preparing for a party. Maria realizes she forgot to fill the ice cube trays in order to have ice for the punch. Elena says that she remembers reading somewhere that hot water freezes faster than cold water. Maria is skeptical. She learned in her physics class that the hotter the liquid, the faster the molecules are moving. Since hot water molecules have to slow down more than cold water molecules to become ice, Maria thinks that it will take hot water longer to freeze than cold water. The girls decide to conduct a scientific experiment to determine whether it is faster to make ice cubes with hot water or cold water.

What is Maria's hypothesis?

a)

It will take hot water longer to freeze than cold water.

b)

Hot water molecules move faster than cold water molecules.

c)

Elena is crazy.

d)

The temperature of the water does not change the time it takes to make ice.

What are the independent and dependent variables?

a)

The independent variable is the temperature of the water, and the dependent variable is the time it takes for the water to freeze.

b)

The independent variable is the freezer you are freezing the water in, and the dependent variable is the time it takes the water to freeze.

c)

The independent variable is the type of ice tray you are using, and the dependent variable is the temperature of the freezer.

d)

The independent variable is the cost of ice at the gas station, and the dependent variable is the amount of ice you need.
