Crosscutting Concepts
In the last unit, students explored animal behaviors of parents and offspring that help the offspring survive and then designed a dam to stop the flow of water. In this unit, students explore the science phenomena of how animals communicate with one another using sound.
In the last unit, students explored the relationship between vibrations and sound. In this unit, students continue to explore the phenomena of human senses, focusing on how objects can be seen when they are illuminated by a source of light, and how light passes through opaque, transparent, and translucent materials differently. Students then investigate how a beam of light changes when it hits a mirror.
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 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 this unit, students explore the phenomena of Earth landforms and the water cycle. Once students have modeled landforms and created maps showing the shapes and kinds of land and bodies of water, students analyze how water moves over the land as it flows downhill because of gravity and cycles between solid and liquid depending on the amount of heat present.
In the last unit, students explored how living things are found in different habitats around the planet and depend on both living and nonliving parts of their environment for survival. In this unit, students focus on plants. They begin with an experiment that investigates the science phenomena of how light and water help plants grow from a seed into an adult plant, and then focus on the function of flowers, which produce seeds.
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 stimulate the movement of tectonic plates and analyze maps to observe how plate boundaries create patterns in Earth’s features. In this lesson, they build on that knowledge to observe the science phenomenon of how water erodes sediment. This page highlights key components of this lesson.
In this unit, students study Earth’s systems, analyzing the science phenomena of natural processes that shape Earth’s surface. In this lesson, students analyze clues in Earth’s rock to determine how Earth’s surface has changed over time. This page is a high-level extract of this lesson.
In this unit, students explore the science phenomena of Earth systems by studying aquifers, comparing the ability of different Earth materials to hold water. In this lesson, they build on that knowledge to engineer permeable pavement that can solve the problems of urban flooding and water pollution. This page showcases key components of this lesson.
In this unit, students focus on Earth’s interacting systems, evaluating how the hydrosphere and geosphere are shaped by one another. In this lesson, they analyze how people use dams to harness the energy in water, and how dams impact the environment. This page highlights each element of this lesson.
