Coherent Students build understanding by connecting ideas from lesson to lesson. At its core, IQWST engages students in scientific practices as they experience, investigate, model, and explain phenomena while learning core ideas and engaging in concepts that cross disciplinary boundaries. Students build understanding by connecting ideas from lesson to lesson, from module to module, and across the middle grades. The curriculum is: Phenomena driven: Students experience phenomena firsthand where possible, secondhand where not possible, but always so that the goal of science learning is to be able to explain phenomena—to explain how and why things in the natural world happen as they do.
Coherent: Students build understanding through a progression within each grade level and across grade levels, learning critical Disciplinary Core Ideas, Crosscutting Concepts, and Science and Engineering Practices across content areas and grades. Curricular coherence—revising and building on ideas across time—provides students with opportunities to develop, reinforce, and apply their understandings on an ongoing basis throughout their middle school years. Three dimensional: Every lesson engages students in one or more Practices and one or more Crosscutting Concepts, as student understanding of core ideas builds so that they are poised to meet every CA NGSS standard over time. Disciplinary Core Ideas are typically addressed in multiple lessons, with the aim of developing depth of understanding rather than simply achieving coverage.
Scientific practices are used singly or in combination, so that students engage meaningfully in the work of scientists as they explore and learn core ideas. Crosscutting Concepts thread throughout the curriculum, repeatedly revisited so that students construct deep understanding of the ideas as they apply to each science discipline. Discourse centered: Combining small-group and whole-group discussion in every lesson, with talk supported by tools such as a Driving Question Board, a Word Wall, and others, students have multiple opportunities to hear and to use the language of science. Talk is used as a way to share ideas, to think together, to problem solve, and to make sense of in-class science, everyday experiences, and the larger world.
For all: IQWST engages all students with shared phenomena, common investigations, and opportunities to draw upon and connect their everyday life experiences with science content. As students read, write, and talk about their experiences in a language-rich environment, every student has the opportunity to achieve success in STEM. Modules 6. 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. Pursuing their questions avoids the traditional treatment of body systems in which systems are presented one after another, with the details of 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. 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 what causes variations in local weather events and global climate patterns. Students investigate the flow of matter and energy throughout the atmosphere and between them and the air around them, and they develop models of processes such as conduction and convection. The module focuses on the movement of matter air and water , and the role that energy plays in that movement. Students create models of what causes weather to change. By looking at weather as yet another complex system made up of sub-systems, students are able to construct an explanation for why predicting the weather is challenging.
This module focuses on heredity, and how traits pass from one generation to the next in both plants and animals, including humans. The organizing theme is comparing organisms; students investigate what makes them similar or different, and develop a model of inheritance to help them understand heredity. They then use the model of inheritance to explain and predict phenomena. Given that organisms need to reproduce in order to pass on their traits, the module also explores structures and behaviors of some organisms that enable them to reproduce. This module builds foundational knowledge and explores underlying mechanisms for inherited traits that is built on when investigating populations and change over time in 8th grade.
This module focuses on energy transfer as a mechanism for understanding issues related to global warming and climate change and the effects that humans have on both. Using land, water, air, and organisms as focal points, the module investigates how humans have impacted those components of the Earth system. Students analyze a human-impact problem and design solutions to minimize its effects, and they consider the consequences of those designs for Earth and its inhabitants.
Once encountered here, climate change is able to be addressed in future modules, including its importance in sustainability, addressed in 8th 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 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 air, and then generalize their models to all gases. In an engineering-focused lesson, students investigate fossil fuels derived from those resources.
The foundational understanding of the particle nature of all matter is built upon in all modules that follow this one. This module is a project-based module that builds on core science concepts such as the particle nature of matter, and substances and their properties, with emphasis on students designing investigations and figuring out and explaining phenomena.
Students investigate what it means to make new substances products from old substances reactants via chemical reactions. Students make soap from fat, make a bioplastic from cornstarch, and engage in several investigations that include molecular modeling experiences that support them in developing a deeper, molecular understanding of phase changes, mixtures, and chemical reactions. The core science concepts explored in the module—especially those related to matter and its interactions and to energy—are instrumental in modules that follow, and for future science learning. This module explores aspects of the human system the body and Earth systems large-scale changes on Earth in a manner that enables students to ultimately determine that these two seemingly unrelated entities have important things in common, especially that both are dynamic changing systems through which matter cycles and energy flows.
They especially focus on molecular aspects of how food provides organisms with energy and building blocks for growth and repair; the chemical reactions and energy transformations that occur during photosynthesis and cellular respiration; the biological processes that support these processes; the interdependence of organisms and organisms and their environment; and the changing around us including plate tectonics. The module culminates in students being able to answer the Driving Question with a complete, evidence-based explanation that draws connections among Earth and human systems as dynamic and always interrelated, a big idea that informs future learning.
In this module, they continue investigating the biosphere, building understanding of how organisms depend on each other as well as how they can be affected by events that disrupt ecosystem function. Over the course of the module, students will learn more about why food is important building on what they learned about the body in 6th grade and about food at the molecular level in the previous module , investigate why different structures are needed and how they are used by organisms to eat and reproduce, and investigate relationships between organisms e. As they work to solve a mystery in which they investigate an invasive species, students will also investigate abiotic factors that affect ecosystems.
The module concludes with two engineering-themed activities in which students explore ways that humans can participate in solving ecosystem problems. Students engage in a group or independent research project in which they apply everything they have learned either to problems caused by a local invasive species or to another local environmental problem, and consider how it might be solved.
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 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 addresses technological advances in their Module 8. Four interesting devices provide a common experience for all students to begin investigation of force and motion in the larger universe and in the world at their fingertips, and later lessons circle back to making sense of the anchoring phenomenon. This practice of exploring, asking questions, and then continuing to revisit—each time knowing a little more of the science of what is happening—enables students to learn core ideas that explain a range of phenomena in the real world about how things start, continue, and stop moving.
An engineering design activity provides an opportunity to apply and to develop deeper conceptual understanding of particular types of force. These important ideas, from different fields of science, provide data that scientists have assembled as evidence of how change over time has occurred. The module focuses on developing models in both life and Earth sciences, and applying them consistently. The application of these models, throughout history, elucidates the story of evolution. The module concludes with a look at human intervention in population change in the form of selective breeding and genetic modification of plants and animals, which some students will likely choose to carry over into Module 8. In 6th and 7th grades, students investigated Earth and human systems as they continuously, and over time, impact one another. In 8th grade, students have learned about how the Earth and biosystems began, and the processes that enable these systems to continue to operate, and how they may be considered a basis for predicting future events.
The goal for this end-of-middle-school module is for students to develop an evidence-based argument to explain how direct and indirect changes to natural systems, due to issues related to human interaction including population growth and increased consumption , influences those natural systems, and how they can be an agent for change. That is, students build understanding of DCIs, CCCs, and SEPs in a coherent manner from one lesson to the next, with each activity ending with a new question or a not-yet-solved problem that is addressed in the following activity. Hence, from a student perspective, a story is built from lesson to lesson within each module, with the aim of answering the Driving Question as a complete, evidence-based explanation.
The unique opportunity that the integrated version provides is for implementation of a yearlong storyline that enables students at each grade level to connect one module to another across the school year. Addressing Storylines with Students The storylines described below are written from a student perspective. The broad storylines provide shape for each school year and, along with the transition ideas, help illuminate the rationale and vision for the curriculum sequence in the IQWST Integrated Edition. The transition statements provide language you may use with students altered as you wish to build a story from module to module within each grade level and from one year to the next. This kind of connection, and the coherence already built into the modules, helps students maintain a conceptual thread over time.
That way, each module is seen not as a separate topic, distinct from those before and after it, but as part of an entire middle school learning experience in which building understanding and connecting ideas is at the foundation of the science curriculum. Grade-Level Storylines Grade 6 Broad storyline: All organisms including me are systems that are part of even larger systems; these systems all interact with and affect each other in important ways.
Module 6. Transitions: From Module 6. For example, we are directly affected by the system all around us that creates the weather. How does weather affect us? What makes different kinds of weather happen? From Module 6. What factors that are inside us affect each of us? For example, what factors affect who you are and what you look like? Do you think that the environmental affects who you are and what you look like? Module 7. Transitions: From 6th grade to 7th grade: In 6th grade, you investigated what makes the human body a system, and you spent the year looking at humans as part of many nesting systems that all interact with each other. From Module 7.
