  1. Bernie puts some ice in a cup and poured somecold tea over the ice. He set the filled cup on the kitchen table. In a few minutes he noticed that there were drops of water all over the outside of the cup. Where did the drops of water most likely come from?
  1. They evaporated out of the air above the cold liquid.
  2. They condensed out of the air surrounding the cold cup.
  3. They dripped off the ice cubes as he put them into the cup.
  4. They came off his hands after holding the melting ice cubes.

Explanation:
Water drops are liquid. When water vapor condenses, it changes from a gas back to a liquid. The water drops on the outside of the glass cannot come from the ice cubes inside the glass or from his hands.
  1. Water runs down creeks and rivers until it flows into the ocean. At what stage in the water cycle does the water return to the creeks and rivers?
  1. condensation
  2. evaporation
  3. precipitation
  4. vapor formation

Explanation:
During the water cycle, precipitation returns water to creeks and rivers.
  1. Padma took a bottle of water with her when she went to play soccer. She wanted to make sure none of it evaporated from the bottle while she was playing. What should she do to keep the water from evaporating?
  1. Screw the top on loosely and set it in the Sun.
  2. Put the top on tightly and leave it in the shade.
  3. Leave the top off the bottle and set it in the Sun.
  4. Screw the top on loosely and keep it in the shade.

Explanation:
Keeping a lid on a bottle prevents the water from evaporating. Keeping it in the shade will slow down the evaporation.
  1. On a cold day in winter, Jasmine breathed on the cold car window. The window fogged up enough so that she could write her name on the glass with her finger. Why did the fog form on the window?
  1. Her warm breath caused precipitation when it hit the cold air.
  2. The moisture in her breath condensed when it hit the cold glass.
  3. The warmth of her breath melted the clear layer of ice on the window.
  4. Her breath contained moisture droplets that evaporated against the window.

Explanation:
When water vapor condenses, it changes from a gas back to a liquid. Jasmine’s warm breath is a gas that touches the cold window and causes the moist vapor to turn back to a liquid.
  1. If Walter puts a bucket of water out in the Sun on a hot, windy day, what will happen to the water level in the bucket?
  1. The water level will go down as the water evaporates from the bucket.
  2. The water level will rise as water condenses from the air above the bucket.
  3. The water level will stay the same since the water is protected from the wind.
  4. The water level will only go down if the wind makes water splash out of the bucket.

Explanation:
On a sunny, hot and windy day the water in the bucket will increase in temperature. That will make it evaporate, and the water level in the bucket will go down.
