Use mathematics and computational thinking to compare the quantity of saltwater and freshwater in various reservoirs to provide evidence for the distribution of water on Earth. Emphasize reservoirs such as oceans, lakes, rivers, glaciers, groundwater, and polar ice caps.
In this unit, students focus on the science phenomena of Earth’s interacting systems, evaluating how the hydrosphere and geosphere are shaped by one another. In the first lesson of the unit, students conduct an experiment to determine how the particle size of an Earth material affects its permeability to water. This page highlights key excerpts from the components of this lesson.
In the last unit, students learned about matter as they explored Earth’s position in the solar system. In this unit, students discuss how the sun provides light and heat to Earth, powering the water cycle, which in turn influences weather and climate. Students analyze the science phenomena of weather patterns in specific regions during a particular season.
In this unit, students analyze the phenomena of Earth’s interacting systems, focusing on how the hydrosphere interacts with and is influenced by the other systems. In this lesson, students graph and model the distribution of fresh water and salt water on Earth and use a physical model to analyze how fresh water moves and becomes salty. This page showcases each section of this lesson.
In this unit, students analyze the science phenomena of the important role that oceans play in regulating Earth’s climate. In this lesson, they focus on how oceans interact with other Earth systems to distribute water and heat around the planet, resulting in various weather patterns, including hurricanes. This page highlights key components of this lesson.
