Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
In 2nd grade, students conduct investigations, carry out experiments, and apply their scientific knowledge to engineer prototype solutions. In this unit, students investigate the science phenomenon of properties of different kinds of matter, connecting a material’s properties with the functions for which it is used.
In this unit, students are introduced to scientific exploration as they observe and test the properties of different kinds of matter. For this lesson, students continue their exploration of properties of matter by classifying different kinds of objects according to observable properties.
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 lesson, students model the solar system and analyze Earth’s place in the system as well as how the force of gravity causes the planets to move around the sun in predictable, regular paths. This page serves to highlight the key components of this lesson.
In the last unit, students observed butterflies moving through their life cycle, explored how butterflies are pollinators, and then designed a hand pollinator. In this unit, students explore the science phenomena of how shelters help animals survive in their environment and then design a prototype burrow-like structure to keep a burrowing owl cool in hot temperatures.
In this unit, students analyze the phenomena of matter, forces, and energy. In this lesson, they compare the effects of unbalanced versus balanced forces on objects. They then evaluate how matter interacts with and is changed by energy, which transfers from one object or system to another. This page showcases key components of this lesson.
In this unit, students explore matter, forces, and energy. In this lesson, students evaluate the science phenomena of how matter interacts with and is changed by energy, which transfers from one object or system to another. This page is a high-level extract of the components of this lesson.
In this unit, students are introduced to the scientific process as they analyze matter in the universe and Earth’s place in the solar system. For the first lesson in this unit, they conduct an experiment to compare the masses of two different substances, analyzing how matter is never created or destroyed. Students also discuss how all matter in the universe is made up of different combinations of atoms formed from chemical reactions. This page highlights key parts of this lesson.
In this unit, students continue to explore science phenomena related to energy, focusing on how energy is transferred in circuits and can do work, such as spinning a motor. Students begin with this lesson on exploring the basic phenomena of direct current energy flowing through parts of a simple and series circuit.
In this unit, students explore the science phenomena of how energy is transferred in a circuit to do work. In this lesson, students figure out the phenomena affecting the left and right movement of an electric car. This page is a high-level extract of this lesson.

In this unit, students explore science phenomena of the life forms that live on Earth, analyzing the cellular structures that make up complex organisms and figuring out how different groups of cells work together to keep the organism functioning properly. This page shows extracts from each part of this lesson.
