7.PS.3

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 several phenomena that relate to cooking. In this lesson, students evaluate chemical reactions, and use that knowledge to engineer a prototype that transfers energy by chemical processes. This page showcases key components 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 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. This page showcases all the components of this lesson.

In this unit, students explore the organisms that live on Earth’s surface, analyzing how living things are made of cells, which have certain requirements for survival, including food, water, and energy. In this lesson, students figure out the phenomena of energy transfer in living systems with a focus on how energy and matter flow through organisms. This page showcases excerpts from components of this lesson.

In this unit, students explore phenomena related to the relationship between forces and motion and how energy is converted from one form to another in an energy system. This page is a high-level extract of the first lesson from this unit which has students investigating the connection between an object’s mass and the force needed to change its motion.

In this unit, students analyze the science phenomena of connections between energy, forces, and motion. In this lesson, students use data to construct an explanation about phenomena that occur because of the relationships between an object’s kinetic energy, its mass, and its speed. This page provides an overview of this lesson.

In this unit, students explore the relationship between the phenomena of forces and motion and how energy is converted from one form to another in an energy system. In this lesson, students design a vehicle that can travel over a surface on a cushion of air. This page highlights key parts of this lesson.

In this unit, students connect their explorations of Earth and life sciences with physical sciences with an exploration into the relationship between magnetism and electricity. In this lesson, they explore the interactions between magnets and electricity. This page is a high-level extract of this lesson.

In this unit, students are introduced to the phenomena of magnetic and electric fields as they explore how objects can interact with other objects without coming into contact with them. For this lesson, students apply scientific concepts to engineer wind turbines that use a generator to produce electricity. This page provides an overview of this lesson.

In this unit, students explore the science phenomena of interactions between energy and matter, analyzing how matter can only change when enough energy is present. In this lesson, they investigate the structure of molecules, relating this structure to the matter’s properties. This page is a high-level extract 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. 

In this unit, students focus on the Earth-Sun-moon system to explore how gravity pulls objects including satellites into orbit. In this lesson, students engineer an insulating solution for a prototype satellite that minimizes the amount of thermal energy transferred into or out of it.

In this unit, students investigate the relationship between gravity, motion, and energy. Students begin by questioning how the amount of potential energy stored in an energy system changes when objects are different heights above the ground.
