Support an argument that plants get the materials (i.e. carbon dioxide, water, sunlight) they need for growth chiefly from air and water.
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 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 focus on the biosphere, analyzing how living things interact with one another and their environment for survival. In this lesson, students figure out the science phenomenon of how plants gather energy and nutrients. This page is a high-level extract of this lesson.
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 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.
