Obtain, evaluate, and communicate information to explain the differences between a physical change and a chemical change.
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 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 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 study the processes that shape Earth’s surface, focusing on the formation of minerals (such as diamonds) and rocks. In this lesson, they explore the phenomena exhibited in the properties of rocks and minerals to figure out how the properties of different minerals are a tool to identify them. This page is a high-level overview of this lesson.
In this unit, students use sleds and roller coasters to explore the relationship between energy, forces, and motion. In this lesson, students apply what they know about energy and forces to engineer a roller coaster. This page is a high-level extract of this lesson.
In this unit, students continue to explore forces and energy, focusing on the science phenomenon of how electrical energy can be transferred from one place to another to do work. In this lesson, students build series and parallel circuits, measuring the amount of current that moves through each circuit with one and two light bulbs. This page highlights some components of that lesson.
In this unit, students explore the science phenomenon of electric currents and electrical energy. In this lesson, students figure out energy transfers, electricity, and circuits in the context of an electromagnetic motor system. This page showcases each key section of this lesson.
