Predict and investigate that water can change from a liquid to a solid (freeze),and back again (melt), or from a liquid to a gas (evaporation), and back again (condensation) as the result of temperature changes.
In 3rd grade, students ask questions and conduct experiments to explore the world around them. In this unit, students unpack the phenomena of tiny particles called atoms that make up all matter in the universe. This page showcases key parts of the first lesson in this unit.
In this unit, students use the scientific process to analyze Earth’s place in the solar system. They begin by modeling how matter is made up of tiny particles called atoms, and changes state when heat is added or removed. This page provides an overview of lesson 1B in which students explore the science phenomena of how heat affects matter.
In this unit, students stimulate the movement of tectonic plates and analyze maps to observe how plate boundaries create patterns in Earth’s features. In this lesson, they build on that knowledge to observe the science phenomenon of how water erodes sediment. This page highlights key 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 discuss the science phenomena of how matter has different properties depending on the number and kind of atoms that make it up. In this lesson, they observe how forces act on matter, focusing on how unbalanced forces cause objects to move. This page provides a high-level extract of this lesson.
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.
