Water Planet
Students know most of Earth's water is present as salt water in the oceans, which cover most of Earth's surface.
Students know that the amount of fresh water located in rivers, lakes, underground sources, and glaciers is limited and that its availability can be extended by recycling and decreasing the use of water.

Students know the Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium.
Students know the solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets.

Galileo Galilei (1564-1642)
Students will identify the dependent and controlled variables in an investigation.
Students will identify a single independent variable in a scientific investigation and explain how this variable can be used to collect information to answer a question about the results of the experiment.
Students know when liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled below the freezing point of water.Students know uneven heating of Earth causes air movements (convection currents).
Students know that the Earth's atmosphere exerts a pressure that decreases with distance above Earth's surface and that at any point it exerts this pressure equally in all directions.
Students know water vapor in the air moves from one place to another and can form fog or clouds, which are tiny droplets of water or ice, and can fall to Earth as rain, hail, sleet, or snow.
Students know the influence that the ocean has on the weather and the role that the water cycle plays in weather patterns.
Hurricanes, Thunderstorms, Tornadoes, Tsunamis, Drought, and Floods
Students know the influence that the ocean has on the weather and the role that the water cycle plays in weather patterns.
Students know the causes and effects of different types of severe weather.
Students know how to use weather maps and date to predict local weather and know that weather forecasts depend on many variables.
