Ecosystems: Interactions Energy and Dynamics 10

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 are introduced to the interdependence of living things and their environment as they analyze how individual organisms are suited to their particular environment, but all organisms require energy and nutrients to survive.

In this unit, students figure out connections between genes and heredity to evolution, focusing on figuring out the phenomena of how both genetic information and the environment influence how a population develops over time. Students investigate different kinds of evidence for life’s shared ancestry and then experiment with how adaptations help some organisms survive. Students end with an investigation into artificial selection.

In this unit, students figure out the interconnectedness of genetics, heredity, and evolution. For this lesson, students create an experiment to observe the phenomenon of natural selection determining which organisms are most likely to survive and pass on their traits. This page showcases parts of key components of the lesson.

In this unit, students apply what they know about genes and heredity to evolution, focusing on how both genetic information and the environment influence the phenomena of how a population develops over time. In this lesson, students explore the phenomena of how adaptations help some organisms survive. Students also investigate artificial selection. This page showcases key parts of this lesson.

In this unit, students focus on the relationship between an organism’s cellular structure and the ability of the organism to access energy to carry out essential life functions. Students begin by examining prokaryotic and eukaryotic cells under the microscope and then compare organelles in plant and animal cells in this lesson. This page is a high-level extract of this lesson.

In this unit, students explore the organisms that live on Earth’s surface, analyzing how living things are made of cells, which have certain requirements for survival, including food, water, and energy. In this lesson, students figure out the phenomena of energy transfer in living systems with a focus on how energy and matter flow through organisms. This page showcases excerpts from components of this lesson.

In this unit, students analyze phenomena of inheritance in how living things pass along their genes to offspring. Students evaluate the role of DNA and chromosomes in heredity in this lesson. This page is a high-level extract of this lesson.

In this unit, students discover how life reproduces at the cellular level, analyzing the science phenomena of how genetic information is stored in chromosomes. In this lesson, students observe mitosis in plants and animals. This page shows key components of this lesson.

IIn this unit, students analyze the science phenomena of inheritance, how living things pass along their genes to offspring. Students evaluate the role of DNA and chromosomes in heredity, and compare the two forms of cell division: the phenomena mitosis and phenomena meiosis. This page shows key components of this lesson on reproduction.

In this unit, students focus on the phenomena of rocky shore ecosystems and the science phenomena of how organisms interact. For this lesson, students analyze how adaptations allow for the survival of different organisms, specifically sea star structures. This 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 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 explore the phenomena of diversity of life on Earth and consider how living things pass on traits to their offspring while also adapting to meet the needs of the environment. In this lesson, students figure out how scientists use the fossil record for clues to how life has evolved over time. This page highlights key parts of this lesson.
