Developing and using models

In this unit, students explore science phenomena including reproduction, DNA, and inherited traits. In this lesson, students investigate how mutations are a phenomena caused by structural changes to the DNA. This page highlights key components of this lesson.

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 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 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 analyze the phenomena that have shaped Earth’s surface, analyzing how gravitational energy moves glaciers, which have sculpted the land over time. This page showcases elements of the first lesson which focuses on glacier motion.

In this unit, students are introduced to the dynamic nature of ecosystems and how disturbances affect them. In this lesson, students observe the effects of an oil spill on the ability of plants to photosynthesize, which can harm an entire ecosystem. This page is a high-level extract of this lesson.

In this unit, students focus on the phenomena of Earth’s ice as they model how glaciers shape Earth’s surface. In this lesson, they investigate how scientists use ice cores to reconstruct Earth’s past climates and environments. This page is a high-level extract of this lesson.

In this unit, students focus on phenomena related to Earth’s ice as they model how glaciers shape Earth’s surface, and investigate how scientists use ice cores to reconstruct Earth’s past climates and environments. In this lesson, students analyze how scientists can use the science phenomena of fossils in rock layers as evidence for past changes on Earth. This page showcases all the components 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 focus on 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 they explore the phenomena of cellular membranes. This page highlights key parts 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.
