- Water Unit
• The water cycle is ongoing and is powered by the sun. Water circulates through the Earth's crust and
atmosphere as part of the water cycle.
• Water can exist in three states of matter: solid, liquid, gas.
• Clouds are formed when condensation occurs in the atmosphere.
• When liquid water evaporates, it turns into a gas in the air and if cooled can reappear as a liquid or a solid. Demonstrate how water changes states from solid (ice) to liquid (water) to gas (water vapor/steam) and changes from gas to liquid to solid.
• Identify the temperatures at which water becomes a solid and at which water becomes a gas.
• Investigate how clouds are formed.
• Explain the water cycle (evaporation, condensation, and precipitation).
Investigate different forms of precipitation and sky conditions (rain, snow, sleet, hail, clouds, and fog).
- Weather Unit
How does the weather reporter know what the weather will be tomorrow?
• Identify weather instruments and explain how each is used in gathering weather data and making forecasts
(thermometer, rain gauge, barometer, wind vane, anemometer).
• Using a weather map, identify the fronts, temperature, and precipitation and use the information to interpret the weather conditions.
• Use observations and records of weather conditions to predict weather patterns throughout the year.
• Differentiate Between Weather and Climate
