Obtain, evaluate, and communicate information about the roles of organisms and the flow of energy within an ecosystem.
In this unit, students focus on the biosphere and how living things depend on their environment and one another for survival. In this first lesson of the unit, they explore the science phenomena of the flow of energy through a food web. This page outlines key parts of the lesson.
In this lesson, students evaluate the science phenomena of how organisms are affected when the environment changes. Students carry out an experiment to analyze two possible solutions that could be used to help a population of harpy eagles recover from the impacts of deforestation over time. This is a high-level extract of this lesson.
In this unit, students explore how living things depend on their environment and one another for survival. In this lesson, students discover phenomena surrounding how frogs have different internal and external structures throughout their life cycle that enable them to survive in their environments. This page highlights components of this lesson.
In this unit, students analyze how living things have specific structures that allow them to function in different environments. They trace how energy flows through a tropical wetland food web, and then test how temperature affects a plant’s ability to transpire through its leaves, affecting its ability to grow. This page is a high-level extract of this lesson on plant structures.
In this unit, students explore the science phenomena of the interdependence of living things and their environment as they analyze how individual organisms are suited to their particular environment. In this lesson, students evaluate how Earth’s biomes have changed over geologic time, studying fossils for clues of the past.
In this unit, students focus on individual organisms, analyzing the science phenomena of life cycles and the inheritance of traits. This lesson has students observing the patterns caused by the changes an organism goes through as it moves through its life cycle. This page is a high-level extract from the first lesson in this unit.
In this unit, students analyze how matter cycles between the living and nonliving parts of an ecosystem. They compare plant and animal cells, figuring out how internal structures help an organism get energy. Then, in this lesson, students figure out how energy flows and matter cycles through a food web, and investigate the phenomena of how plants convert non-food sources, such as light, air, and water, into food sources. This page showcases key elements of this lesson.
In this unit, students focus on the biosphere, analyzing the science phenomena of how living things interact with one another and their environment for survival. In this lesson, students focus on the role of decomposition as they design a compositing solution. This page is a high-level extract of this lesson.
In this unit, students focus on how environmental changes impact the ability of organisms to survive, grow, and reproduce, passing their traits on to future generations. In this lesson, students continue their analysis of how a plant’s structures allow it to grow and develop, focusing on how a change in the environment such as pollution can impact a plant’s ability to complete its life cycle. Specifically, students investigate how acid rain affects the external structures of aquatic plants. This page provides an overview of this lesson.
In this unit, students evaluate the science phenomena of how a change to an ecosystem can impact the living things that make it up. In this lesson, students explore how a change to the kind of plants in an environment results in a ripple effect phenomena on predation in the area. This page is a high-level extract of this lesson.
