After a rainstorm, a group of students notices puddles on the sidewalk. Later that afternoon the students observe a change in the puddles. What caused the water in the puddle to disappear?

• Shadows covered the sidewalk.

• The Sun’s heat evaporated the water.

• The rainstorms continued all day.

• The water changed into ice.

• become heavier.

• turn into ice.

A science teacher placed a beaker of water in a windowsill. Students measured the volume of water in the beaker for four weeks. What might have caused the change in volume?

• Ice was added to the water.

• The water was observed every day.

• Chemicals were stored near the water.

• The water was heated by the sun.

Students created a model of the water cycle by heating a beaker of water on a hot plate until it boiled. They carefully held a metal pan of ice cubes where water vapor was rising from the beaker and water drops began to form on the bottom of the metal pan. The water drops formed on the bottom of the pan because –

• the pan was made of metal.

• the water vapor cooled.

• the ice was a solid.

• the hot plate uses electricity

Sometimes a burning candle will have wax dripping down the side. This happens because the heat of the flame –

• turns the wax of the candle to a liquid.

• causes water to collect on the candle.

• creates tiny air currents around the candle.

• uses some of the gases in the air.

What causes water to freeze solid when placed in a freezer? The freezer -

• adds heat to the water.

• puts electricity into the water.

• takes heat away from the water.

• does not let light shine on the water.
