Obtaining, evaluating, and communicating information

In this unit, students explore science phenomena of the life forms that live on Earth, analyzing the cellular structures that make up complex organisms and figuring out how different groups of cells work together to keep the organism functioning properly. This page shows extracts from each part of this lesson.

In this unit, students compare the science phenomena of bacterial, plant, and animal cells, figuring out similarities among them all as well as differences. Students then conduct an experiment into how yeast cells extract energy from food molecules. This page highlights components of this lesson. 

In this unit, students explore science phenomena related to life forms that live on Earth, analyzing the cellular structures that make up complex organisms and how different groups of cells work together to keep the organism functioning properly. In this lesson, students test the effect of sucrose concentration on the heart rate of daphnia, observing how different organ systems work together. This page provides a high-level extract of this lesson.

In this unit, students investigate phenomena related to how organisms pass on traits to their offspring. Students begin, in this lesson, with an investigation into how DNA codes for proteins, which determine an organism’s traits. This page provides a high level overview of this lesson. 

In this unit, students continue their exploration of the cell with a focus on the phenomenon of DNA. Students use models to compare and contrast asexual and sexual reproduction and to investigate how traits are passed down from parents to offspring. This page is a high-level extract of this lesson.

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.
