Planning and carrying out investigations

In this unit, students focus on science phenomena related to the diversity of life, analyzing how scientists use the fossil record to tell of how life has evolved over time. In this lesson, students then compare the phenomena of cellular diversity in fungi, plant, and animal cells, exploring how similarities can be used to support evolutionary relationships. This page is a high-level extract of this lesson.

In this lesson, students figure out similarities among the phenomena of cells, specifically the phenomena of inheritance and variation of traits. This page shows key components of this lesson.

In this unit, students explore how life has changed and become more diverse over time. In this lesson, students dissect fungi to figure out how they reproduce. This page highlights components of this lesson. 

In this unit, students focus on the structure and function of specialized cells, tissues, and organs in the phenomena of complex multicellular organisms, and they explore how the body processes information gathered by sensory receptors. In this lesson, they develop a model for a human organ system and then observe different human cells to understand how structure influences function. This page highlights each part of this lesson.

In this unit, students explore the structure and function of the human body by developing models of the interactions within and between systems. In this lesson, they investigate the science phenomena of cellular hierarchy in multicellular organisms, including major organ systems and their functions.

In this unit, students discover the structure and function of specialized cells, tissues, and organs in complex multicellular organisms, and they explore the phenomena of how the body processes information gathered by sensory receptors. This page is a high-level lesson extract. 

In this unit, students explore the phenomena of forest ecosystems, studying the science phenomena of interactions between living things and the environment. In this lesson, students investigate how plants carry out photosynthesis to convert the sun’s energy into a form of energy they can use to grow and develop. This page highlights key parts of this lesson. 

In this unit, students explore forest ecosystems, studying the science phenomena of interactions between living things and the environment. In this lesson, students build on their understanding of how energy affects the growth of organisms by exploring the phenomena of forest food webs, and analyzing how the phenomena of drought can have a ripple effect through the ecosystem. This page showcases all components of this lesson.

In this unit, students explore how engineers and architects design structures that help human populations survive and thrive in their environment. Students take on the challenges of civil engineers as they design different types of bridges to discover a design that can carry the maximum load. This page highlights the components of this lesson.

In this lesson students focus on phenomena created by levers, exploring how the structure of the lever determines how much force it can produce to do work. This page is a high-level extract showcasing various parts of the lesson. 

In this lesson, students focus on figuring out the phenomena that is the pitch of a sound and the various factors that determine pitch. This page is a high-level extract of this lesson. 

In this unit, students investigate the relationship between gravity, motion, and energy. Students begin by questioning how the amount of potential energy stored in an energy system changes when objects are different heights above the ground. 

In this unit, students explore phenomena that change Earth’s surface over time, analyzing how weathering, erosion, and convection in the mantle are three phenomena that help to cycle Earth materials.
