This module focuses on the body as a system made up of subsystems, with all parts working together to perform various functions and interacting with the environment. Students’ individual questions about what happens inside their bodies to enable them to do the many types of activities that they enjoy motivate the investigation of various body systems and the role each plays in overall body function. Pursuing their questions avoids the traditional treatment of body systems in which systems are presented one after another, with the details of the structure and function the highlight rather than how systems work, work together, how matter and energy flow through the body, and between the body and the environment around us (i.e., how the outside temperatures make our bodies feel hot or cold). The module focuses on what happens to food and oxygen that enables the body to meet its energy needs as food is eaten and ultimately transported to cells throughout the body. Exploration begins, then, with cells. Tracing the transformation of food to usable energy at the cellular level raises questions about how this happens. By the end of the module, students are able to construct a detailed, evidence-based, grade-level appropriate explanation of what goes on in their bodies to enable them to do an activity they enjoy. The specifics of cellular respiration are in 7th grade.

This module focuses on two overarching ideas: 1) Planet Earth is made up of natural resources that humans rely on and use in a variety of ways, and 2) Each of these resources, regardless of the state of matter, is made up of atoms, joined together in particular configurations called molecules. Students explore key concepts, especially the particle nature of matter, in the context of both physical and Earth sciences. Students first investigate air, modeling odors traveling in the air, and then generalize their models to all gases. Over time and through investigations, they revise and generalize their model to include liquids and solids, all of Earth’s natural resources, and all matter. In an engineering-focused lesson, students investigate fossil fuels derived from those resources. While students come to this module with a general, macro-level understanding of air as made up of molecules (from 6th grade), they learn what it means to be “made up of” molecules, and for molecules to be made up of atoms. The foundational understanding of the particle nature of all matter is built upon in all modules that follow this one.

This module begins with a focus on the forces that formed the universe, and Earth’s solar system, from chaos. Students explore the big bang theory, and the role of gravity as the major force that continues to operate and maintain order in the universe, enabling us to observe predictable patterns in the Earth-sun-moon system. Students then investigate the role that light, in particular, plays in how we observe objects in our solar system, and then shift to the many other important roles that light plays in life on Earth. The scientific principles that explain the behavior of light are the principles that govern much of the behavior of cellular phones, computers, MRI scanners, microwave ovens, nuclear power plants, televisions, satellite communication, GPS, and many other systems. Nearly all the major scientific discoveries and major technological advances made in the last 100 years are based, directly or indirectly, on principles underlying the behavior of light. It is impossible to make sense—scientifically—of the world in which we live without understanding how light propagates and how it interacts with matter. Students are introduced to the electromagnetic spectrum and exploration of the role of visible light in allowing them to examine the universe, and to the role of nonvisible light that has advanced technology. Some students are likely to address technological advances in their Module 8.4 projects.
