Science and Engineering Practices
In this unit, students investigate what makes an object float or sink, exploring the science phenomena of properties of objects that float and sink. This page is a high-level extract of the last lesson in 2nd grade that has students applying their knowledge about the relationship between an object’s properties and its ability to float.
In this unit, students explore the science phenomena of Earth’s weather system and analyze how heat from the sun warms Earth’s surface unevenly, powering the water cycle, which in turn drives weather and climate on the planet. Students create weather instruments to collect and analyze daily weather data.
In this unit, students discover the life cycles of different organisms, tracing how individuals move from birth to growth, reproduction, and death. In this lesson, students analyze the science phenomena of how traits are passed down from parent to offspring. This page provides an overview of all the parts of this lesson.
In this unit, students bring together what they have learned about the interactions of energy and matter to explore the science phenomena of relationships between energy, force, and motion. In this lesson, they investigate how windmills transfer the kinetic energy in wind so that it can be used to do work, and then use that knowledge to analyze balanced and unbalanced forces.
In this unit, students first use windmills to analyze how wind energy provides a force that causes windmills to turn. Then, in this lesson, they explore the science phenomenon of how patterns in motion can be used to predict future movements. This page provides a snapshot of key components of the lesson.
In this unit, students continue to explore the science phenomenon of forces, analyzing how structures have to be able to withstand all of the forces that act on them. Students begin by testing different materials and shapes to see how they respond to different types of forces.
In this unit, students begin an exploration of life sciences. Once students have described the differences between living and nonliving things and analyzed what all living things need to survive, they focus on the parts of plants that help them get what they need to survive.
In this unit, students discuss the science phenomena of how matter has different properties depending on the number and kind of atoms that make it up. In this lesson, they observe how forces act on matter, focusing on how unbalanced forces cause objects to move. This page provides a high-level extract of this lesson.
In this unit, students explore the science phenomena of how all matter in the universe is made up of different combinations of atoms formed from chemical reactions. In this lesson, students use scale models to compare properties of the Sun, Moon, and Earth. This page is a high-level extract of this lesson.
In this unit, students discuss how all matter in the universe is made up of different combinations of atoms formed from chemical reactions. They use scale models to compare properties of the sun, moon, and Earth, and then use that knowledge to analyze the science phenomena of how patterns are formed by the relative positions and movements of the sun, moon, and Earth. This page highlights key components of this lesson on patterns.
In this unit, students analyze the science phenomena of how elements make up minerals, which make up rocks. In this lesson, they explore geologic phenomena that cause Earth’s surface to change over time in predictable patterns. This page is an overview of this lesson.
In this unit, students analyze the phenomena of Earth’s interacting systems, focusing on how the hydrosphere interacts with and is influenced by the other systems. In this lesson, students graph and model the distribution of fresh water and salt water on Earth and use a physical model to analyze how fresh water moves and becomes salty. This page showcases each section of this lesson.
In this unit, students analyze the science phenomena of the important role that oceans play in regulating Earth’s climate. In this lesson, they focus on how oceans interact with other Earth systems to distribute water and heat around the planet, resulting in various weather patterns, including hurricanes. This page highlights key components of this lesson.
