Disciplinary Core Ideas
In this unit, students use what they know about the relationship between energy and matter to investigate phenomena of how energy powers the cycling of Earth materials. They begin with this lesson on modeling the Earth processes that form different kinds of rock. This page provides an overview of this lesson.
In this unit, students are introduced to matter and energy as they learn about how scientists and engineers design materials with specific properties to address a wide range of societal needs. They focus on the basic structure of matter, and how energy changes matter in physical and chemical changes. In this lesson, students focus on the role of energy in changing matter during a chemical reaction phenomena between two substances. This page provides an overview extract of this lesson.
In this unit, students use the phenomenon of why certain materials (such as the materials that make up a baseball) are useful for a particular function to explore the relationship between matter and energy phenomena. In this lesson students manipulate the properties of a polymer bouncy ball by changing the amounts of reactants in a chemical reaction. This page highlights key parts of this lesson.
In this unit, students explore phenomena on the relationship between matter’s structure and its function, and how people can use this knowledge to manufacture new materials and products with specific purposes. Students begin by investigating how matter is changed, but always conserved, in both endothermic and exothermic reactions. In this lesson, students use a manufacturing process to turn raw materials into a finished product. This page showcases key components of this lesson.
In this unit, students explore the natural processes that cause Earth’s surface to change over time, analyzing how energy causes Earth’s matter to transform and cycle from one form to another. In this lesson, they trace phenomena of how energy is transferred in chemical reactions, which allows scientists to produce ethanol to use as an alternative energy source. This page showcases each component of this lesson.
