Review Weather-10

When water freezes, it:

  1. Condenses

    No. Condensation happens when water vapor changes from a gas to a liquid.
  2. Contracts

    No. Water does not take up less space when it freezes.
  3. Expands

    Yes! Unlike most substances, water expands to take up more space when it freezes.
  4. Gains mass.

    No. Changing from one state to another does not cause a change in mass.

SC.3.P.9.1 Describe the changes water undergoes when it changes state through heating and cooling by using familiar scientific terms such as melting, freezing, boiling, evaporation, and condensation.

SC.4.P.8.2 Identify properties and common uses of water in each of its states.

SC.5.E.7.1 Create a model to explain the parts of the water cycle. Water can be a gas, a liquid, or a solid and can go back and forth from one state to another.

SC.5.P.8.1 Compare and contrast the basic properties of solids, liquids, and gases, such as mass, volume, color, texture, and temperature.

SC.6.E.7.2 Investigate and apply how the cycling of water between the atmosphere and hydrosphere has an effect on weather patterns and climate.


UT.4.I.2.b Describe the processes of evaporation, condensation, and precipitation as they relate to the water cycle.

UT.4.I.2.c Identify locations that hold water as it passes through the water cycle (e.g., oceans, atmosphere, fresh surface water, snow, ice, and ground water).


MS-ESS2-4 Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity.
