In this unit, students focus on interactions between matter and energy. In this lesson, students figure out the endothermic and exothermic phenomenon of chemical hot and cold packs to analyze matter and energy in different kinds of chemical reactions. This page is a high-level extract of this lesson.

In this unit, students explore phenomena of 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, students investigate how Earth materials are continually being reshaped and reformed by multiple processes that are powered by energy from Earth’s hot interior and the sun. This page is a high-level extract of this lesson.
In this unit, students explore the relationship between matter and energy using the phenomenon of material properties to discover why certain materials are useful for a particular function. For this lesson, they focus on the role of energy in changing matter during a chemical reaction phenomena between two substances. This page is a high-level 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 parts of this lesson.
In this unit, students build on their knowledge of energy by exploring the relationship between energy and matter. In this lesson students conduct an investigation into the science phenomenon of how energy is transferred in an endothermic reaction. This page provides an overview of this lesson.
