Science and Engineering Practices
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 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 focus on phenomena related to Earth’s ice as they model how glaciers shape Earth’s surface, and investigate how scientists use ice cores to reconstruct Earth’s past climates and environments. In this lesson, students analyze how scientists can use the science phenomena of fossils in rock layers as evidence for past changes on Earth.
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 analyze the phenomenon of our sun as the primary source of energy on Earth. In this lesson, students explore how the sun’s uneven heating of the planet drives weather phenomena and climate phenomena, which result from complex interactions within Earth’s systems. This page is an extract from parts of this lesson.
In this unit, students evaluate how Earth is heated unevenly by investigating how the angle that the sun’s rays hit Earth affects temperatures at different locations. In this lesson, students use their scientific knowledge of phenomena related to global warming and climate to engineer a model greenhouse that reaches a specific temperature. This pages provides a snapshot 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.
