1.       A student takes a bottle of cold water from the refrigerator and leaves it on the counter. Ten minutes later, the student noticed there is now water droplets on the outside of the bottle. Which scientific phenomenon explains the water on the outside of the bottle?

• A.    Condensation because the temperature of the air nearest the bottle increased causing water droplets to form.
• B.    Condensation, because the temperature of the air nearest the bottle decreased causing the water droplets to form.
• C.    Evaporation, because the temperature of the air nearest the bottle increased causing the water droplets to form.
• D.   Evaporation, because the temperature of the air nearest the bottle decreased causing the water droplets to form.

1.       In science class, lab partners are designing an experiment that shows the important steps of the water cycle. For their experimental design, which of the following procedures could BEST be used to demonstrate the difference between condensation and evaporation?

• A.    To show condensation, the lab partners must increase the temperature within the cycle; to show evaporation, they must decrease the temperature.
• B.    To show condensation, the lab partners must decrease the temperature within the cycle; to show evaporation, they must increase the temperature.
• C.    To show condensation, the lab partners must maintain a constant temperature within the cycle; to show evaporation, they must increase the temperature.
• D.   To show condensation, the lab partners must maintain a constant temperature within the cycle; to show evaporation, they must decrease the temperature.

The picture shows a student’s lab setup of a model of the water cycle. In this experiment, the total amount of water inside the container is measured at the beginning, and then again after a full cycle has occurred. Which of the following BEST predicts the outcome of the experiment and explains why?

• A.    The beginning amount of water in the container would be less than the ending amount of water in the container because the water evaporated, decreasing the water level.

• B.    The beginning amount of water in the container would be more than the ending amount of water in the container because the process of condensation increases the water level.

• C.    The beginning and ending amounts of water in the container would be equal because the water that was evaporated increased the water level but then came back as precipitation which decreased the water level again.

• D.   The beginning and ending amounts of water in the container would be equal because the water that was evaporated decreased the water level but then came back as precipitation which increased the water level again.

1.       Why did the egg sink in the freshwater (lake), but floats in the saltwater (ocean)?

• A.  The egg will sink in freshwater because the density of the egg is greater than the density of water.
• B.  The egg will sink in freshwater because the density of the egg is less than the density of water.
• C.  The egg will sink in freshwater because the density of the egg is equal to the density of water.
