IQWST® (Investigating and Questioning our World through Science and Technology), which transforms adolescents into scientists, was developed over a decade by science education, literacy, and learning science specialists from the University of Michigan, Northwestern University, Michigan State University, and the Weizmann Institute of Science, supported by funding from the National Science Foundation. Students investigate questions relevant to their lives by conducting investigations; collecting and analyzing data; developing and using models to explain phenomena, and engaging in argument from evidence, all in a literacy and discourse-rich environment.
Lessons are organized into thematic units such as Can I Believe My Eyes? (Physical Science) and What's Going on Inside Me? (Life Science), that support students as they build understanding of core ideas in science as well as understanding and use of scientific practices. Students also pursue their own original questions in units that integrate the fundamentals of Physical Sciences, Life Science, and Earth & Space Science.
As research indicates, and the Framework for K-12 Science Education and NGSS describe, students learn best when they use coherent materials that support them in building understanding over time.
- Sixth-graders learn about species interactions in ecosystems by investigating data from real-world examples of invasive species.
- Seventh-graders explore properties, chemical reactions, and the conservation of mass by making their own soap materials they have investigated across multiple lessons.
- Eighth-graders race, jump, and crawl in the classroom to measure properties of motion and create graphs based on physics equations.
- Eighth-graders use a computer program to investigate a drop in the Galapagos Islands’ finch population.
By referencing real-world science with which students are familiar or have personal experience, science learning has value to diverse students who can apply what they are learning to their everyday lives. Our learning-by-doing pedagogical approach — paired with the expertise of our Chief Learning Officer Dr. LeeAnn Sutherland, Michigan State Professor Joe Krajcik, Northwestern University Professor Brian Reiser, and Weizmann Institute Senior Scientist David Fortus — engages students as active learners and makes science come alive in ways that research has shown best support the broad range of learners found in every classroom.
Chemistry 1: How Can I Smell Things from a Distance?
In order to contextualize core ideas about the nature of matter, this unit focuses on the everyday life experience of smelling odors whether close to or far from one’s nose. As students investigate this and other phenomena, they develop models of how people smell odors, and use their models to explain and predict what happens in various scenarios. Rather than simply accepting a particle model (that matter is comprised of molecules, which are comprised of atoms), students come to understand this core science idea over time as the only way to explain that air can be compressed, expanded, added to and subtracted from a container. Students then use the particle model to explain why substances have different properties, and to explain the behavior of particles in each state of matter and at a substance’s melting and boiling points during phase change, including the relationship between the movement of molecules and temperature. Students’ model of matter, which is represented both as a drawing and a written explanation, represents a conceptual understanding that “all matter is made of particles in constant motion,” a concept revisited in future IQWST units in physics, chemistry, life science, and Earth science and central to all future science learning.
*Student Edition is Now Available in Spanish.
Chemistry 2: How Can I Make New Stuff From Old Stuff?
The unit builds understanding of core science ideas including the particle nature of matter, energy, and substances and their properties. In order to contextualize chemistry concepts in real-world experiences, the unit focuses on making new substances, specifically making soap from two unlikely substances: fat and sodium hydroxide. Students complete a number of investigations of soap and fat as they further their understanding of substances and properties, and explain what happens when substances interact (i.e., chemical reactions). In that process, they also explore the core idea of the conservation of mass and the crosscutting concept of systems. Each cycle of investigation begins with macroscopic phenomena and includes the use of molecular models to help explain the phenomena.
Chemistry 3: How Does Food Provide My Body with Energy?
This cross-disciplinary units targets core ideas about food, photosynthesis and cellular respiration in the context of living systems. The unit builds core ideas, crosscutting concepts, and scientific practices addressed in other IQWST units, providing an opportunity to synthesize and to deepen understandings. Students address chemical reactions and the energy transformations associated with them, and address their relevance in their own lives and to their own bodies. Students investigate food at the molecular level and explore how cellular respiration, as a chemical reaction, allows organisms to use the energy in food. They also examine photosynthesis as the chemical reaction in which plants transform light energy into chemical energy to store in food. This unit thus builds understanding of a key crosscutting concept—the flow of matter and energy—as students consider what happens in a system during cellular respiration and photosynthesis.
Earth Science 1: How Does Water Shape Our World?
To contextualize core ideas about the water and rock cycles at the middle school level, this unit focuses on selected national parks in the United States and the study of features common and unique to each. In groups, students take on the task of collaborating to develop a visitors’ guide that explains how water has shaped the landscape of a single park. To complete this task, students must understand how water moves through the park, what types of rock are present, and how the water and rock have interacted to shape the land. Students learn where water can be found on, above, and below the Earth’s surface. They learn how water moves and is transformed in the water cycle by investigating evaporation, precipitation, infiltration, and flow. Students also explore how rocks are formed and the properties of different types of rock. Finally, they examine the effects of water on the land by investigating weathering, erosion and deposition. To do so, students engage in relevant scientific practices, address crosscutting concepts, and build understanding of energy and the particle nature of matter as both apply in the study of Earth science.
Earth Science 2: What Makes the Weather Change?
In this unit, students learn about climate by investigating daily, seasonal and annual weather patterns. The unit is organized around students analyzing and interpreting data on either conditions in various cities around the world. Students develop an understanding of the concepts of climate, weather, pattern, and predictability. They also learn how energy from the sun and the variation in earth surface features create the convection cells in the atmosphere that determine large-scale patterns of temperature, clouds, wind, and precipitation.
Earth Science 3: How Is the Earth Changing?
In this unit, students investigate plate tectonics by investigating how the Earth has changed in the past and continues to change today. The unit begins with a historical perspective as students learn how the theory of plate tectonics was developed through the social processes of evidence gathering and explanation in the scientific community. Students then explore the modern explanation for why plates move on Earth’s surface by applying their understanding of convection, built on previous study of convection in the atmosphere, to the Earth’s mantle. They investigate how these internal earth processes drive plate motion and how that motion leads to events such as earthquakes and eruptions, and shape major surface features on Earth, including volcanoes, mountain ranges, islands, and oceanic trenches. They use this conceptual understanding to explain features and events found in selected case-study sites around the world.
Life Science 1: Where Have All the Creatures Gone?
This ecosystem unit focuses on organisms’ needs for survival and what happens when those needs are not met. Throughout the unit, students investigate a specific population change: the decrease in the trout population in the Great Lakes from 1930 to 1990. Because the sea lamprey, as an invasive species in the Great Lakes, is such a fascinating organism, this particular case of population change engages students in learning core science ideas that they can then apply to changes in their local environments or elsewhere. Over the course of their investigation, students learn why food is important, what structures different organisms have in order to eat and reproduce, what the possible relationships are between organisms (e.g. competition, predator/prey, producer/consumer) and what abiotic factors affect ecosystems. All of these pieces help students to invest in developing an evidence-based scientific explanation and engaging in argumentation about why the trout population decreased so dramatically, employing a key scientific practice as they learn core science ideas.
Life Science 2: What’s Going On Inside of Me?
In this unit students investigate how the human body manages to do the complex activities of everyday life. Students investigate organization in body systems and the role of the body’s cells in these systems. To examine the levels of organization in body systems, students track what happens to food as it goes through the digestive system, to the circulatory system, to be delivered all over the body. The investigation of where food needs to go and where it is processed to release and use energy leads to identifying cells as the location where the major functions of processing food for energy and releasing waste occur. Students build on their understanding of food providing energy and building materials from 6th grade biology and on the role of energy in chemical reactions from 7th grade chemistry, and identify energy-releasing chemical reactions as occurring within cells to release the energy from food. Students investigate the link of increased oxygen intake with increased activity and obtain evidence that oxygen is also used at the cellular level in these reactions. The unit concludes with an investigation of how body systems are coordinated and consequences of disruption to various body systems.
Life Science 3: Why Do Organisms Look The Way They Do?
This unit uses investigations of organisms (including people) to raise questions about how similarities and differences between individuals and populations are influenced by inheritance of traits. Students investigate inheritance in plants they grow in class, and investigate pedigrees that document inheritance of human traits, developing a Mendelian model of inheritance to account for the patterns they uncover. Students use this model to explain the source of variation within a population, and why organisms of the same species exhibit many common characteristics. Students examine how changing environmental conditions can influence variation in a population. Through investigations of several data-rich scenarios of population change, students develop a model of how changing environmental conditions can lead to organisms with some variations of traits being more likely to survive and produce offspring, resulting in shifted distributions of those traits in future generations. Students generalize their explanations to develop a model of natural selection as defined by naturally occurring variation in inherited traits, changing environmental conditions and differential survival, addressing most notably the crosscutting concepts of patterns, and of stability and change in systems.
Physical Science 1: Can I Believe My Eyes?
The unit begins with a contextualizing activity in which students view optical illusions that make them uncertain of what they are seeing. They spend the next several weeks investigating light waves and their interaction with matter. To do so, students engage in several scientific practices, with an emphasis on constructing and using models to explain and predict phenomena. Each new investigation causes students to realize that the model they developed to fit one situation does not fit the new one, requiring revision based on new evidence. This practice enables students to engage in modeling in ways similar to those in which scientists develop, use, and revise models they use to explain and predict real-world phenomena. Students continually delve into core science ideas, gaining a deeper understanding of how light moves through space, what happens when it meets matter, how eyes detect light, how colors of light can be perceived, and that some light is non-visible. A conceptual understanding that “light can make things happen” sets the stage for understanding energy, a crosscutting concept revisited in future IQWST units in physics, chemistry, life science, and Earth science and central to all future science learning.
Physical Science 2: Why Do Some Things Stop While Others Keep Going?
Students begin this unit by watching a video of a large Rube Goldberg machine in action, and then explore several apparatuses up close, some of which stop quickly and others continue moving without showing signs of stopping. As students explore the apparatuses and different types of energy, they gain a deeper understanding of how energy is involved in everything in the world, how it can be transformed from one type to another, and how it is transferred between systems, addressing several core ideas and crosscutting concepts. Students use two types of qualitative diagrams as models, engaging in the scientific practice of modeling to represent and explain energy conversions and energy transfer between systems.
Physical Science 3: How Will It Move?
This unit focuses on forces and motion in a variety of contexts: tug-of-war, baseball, planetary motion, chemical bonds, and others. It begins with a surprising anchoring activity in which a ball speeds up unexpectedly, and revisits this phenomenon several times throughout the unit. Students generalize from specific examples to construct principles commonly known as the core ideas of Newton’s laws of motion. The differences between force and energy are emphasized, with rules-of-thumb being generated to decide which concept is more useful in given situations, and to address crosscutting concepts of system models, and energy and matter. The unit integrates several focal scientific practices: planning and carrying out investigations; data gathering, organization, and analysis; developing and using models; and constructing explanations and engaging in argument from evidence.
Seeing is believing, so, grab the popcorn! The Activate Learning video team has traveled the nation visiting many different schools all engaged with our curricula. Watch to see how ALL of our learners are succeeding in investigation-centered STEM.

- Detailed setup videos providing activity setup instructions for appropriate lessons
- Ability for students to digitally compose and submit answers to teachers
- Ability for teachers to provide written feedback to students
- Aggregated reporting of student and class responses, provides a “macro” view of overall progress
Preparing for lessons is oftentimes an intensive and lengthy experience frequently involving several sets of reference materials. And, as teachers know, there is usually a tremendous and sometimes overwhelming amount of resources and information available to help them prepare. IQWST is no exception. So, how best to access this information? In a book-like format? We think there is a better way.
The Interactive Digital Edition takes a more intelligent layered approach to the organization of the various teacher resources available. Rather than the linear construct forced by the confines of a printed book, the Interactive Digital Edition provides the teacher resources at your fingertips within the context of the main content, as a unified and simple-to-use single tool.
As students progress through each lesson, their written responses are sent to the teacher electronically. Teachers receive real-time formative assessment information, enabling them to monitor progress and modify instruction at the individual, small-group, or whole-class level.
LESSON SETUP VIDEOS
In addition to descriptive material, many lessons include video that demonstrates the procedure for setting up investigation equipment or materials.
Quality professional development is crucial for the success of IQWST® because the program invites teachers to rethink previous practices, construct new expectations for student outcomes, and teach in ways they may not have taught before as classroom discourse and pushing student thinking take center stage.

Teaching science became a passion of Curtis Maine’s the day that he first faced students in his classroom in the mountains of North Carolina. After a number of years in North Carolina and Vermont, where he was honored as Teacher of the Year in the high school in which he taught, Curtis began his graduate work at Michigan State University studying Science Education, and then spent the next 20 years teaching in California. There, Curtis developed science curriculum that engaged students by having them do science as if they were themselves scientists, and eventually integrating iPads into the work of classroom science. When he discovered Activate Learning’s middle school science curricula, the fit was perfect, thus upon retiring, Curtis joined the professional development team in order to support other middle school science teachers in implementing cutting edge, research-based curricula. During his career, Curtis taught both high school and middle school science, spending most of his years in middle school, serving as 8th grade Team Leader and Science Department Chair. He continues to be excited by the opportunity to share outstanding science curriculum with teachers around the country.

Claim, Evidence & Reasoning (CER)
Every science teacher understands the value of students being able to explain phenomena, not simply to define vocabulary words or to answer questions that require them to show what they have memorized. But teaching students to construct explanations is challenging.
IQWST® makes the process easier by supporting teachers and students with a systematic approach that includes the now well-known CER framework. The framework divides explanations into three logical, manageable, and teachable components for middle school students: Claim, Evidence, and Reasoning.
We developed the CER framework alongside teachers who were frustrated by their students’ responses to oral and written questions—typically responding in such brief ways that teachers could not adequately assess their students’ understanding. The CER framework was born and developed in IQWST as a result of teachers’ desire to better support their students as scientific thinkers and writers.
To begin, students must be asked questions that require them to think deeply about what they have observed, read, and experienced and to integrate that information as they explain the how or why of phenomena for a specific purpose and audience. Although an explanation must function as a whole, teachers often find it easier to teach the components separately and explicitly.
A claim is a statement of a student’s understanding about a phenomenon or about the results of an investigation; it answers the original question by expressing what he or she is trying to help an audience understand and believe. In practice, teachers often teach that a claim cannot begin with “yes" or “no," and is typically the first sentence of an explanation.
Although a claim does not need to be the first sentence in an explanation, it is helpful for students to learn to construct explanations with specific guidelines that can be varied later. The claim is typically the part of an explanation that students find easiest to include and to identify as they critique others’ explanations. Claims may be made about data that students have been given or that they have gathered themselves. If an investigation has independent and dependent variables, the claim describes the relationship between them. The quality of an explanation is largely dependent on a good question to begin with, so consider first the question. After an investigation, have students return to that question, and their response, in a sentence, is typically a claim.
While data can refer to all the observations that students have collected or analyzed, data become evidence when used to support a claim. A claim is convincing to someone else only when there is strong evidence to support it.
The evidence for explanations can come from investigations students conduct, from observations they make, or from reports of empirical research others have done. In complex situations, more than one claim might be made about a single data set thus having accurate, appropriate, and sufficient evidence is what makes a claim convincing. The idea that multiple claims might be made using the same data develops across the IQWST curriculum as the inquiry activities become more complex, and students’ options for research questions (and resulting claims and evidence) become increasingly open ended. One challenge of the evidence component is that students assume they do not need to describe the data because their teacher and classmates already know what happened! Thus, helping students to decide which data to choose and how to present those data as evidence is a key step in the process of learning to construct an explanation. Significant time must be devoted to helping students understand what counts as good evidence in science, drawn from qualitative and/or quantitative data, and what it means for evidence to be both appropriate and sufficient.
Reasoning is the most challenging for both students and teachers. Reasoning illustrates why particular evidence is the correct evidence to use in support of a particular claim. Reasoning typically includes describing the scientific knowledge or theory, or what IQWST refers to as the Scientific Principle, that applies to a particular claim and evidence. The principles are not given to students, but are “figured out” through their own investigations and in the context of whole-class discussions.
Reasoning requires students to make explicit the steps of their thinking, showing the logic that leads from the evidence to the claim. Critiquing examples of explanations helps students recognize the components and the need for them. They quickly learn to determine what is missing or inadequately expressed—and because they find this easier than constructing their own explanations, it is often a good starting point. Sharing an anonymous example from 3rd period with students from 1st period enables students to learn what to look for without feeling criticized early in the learning process. IQWST provides systematic scaffolding to guide students in constructing explanations of scientific phenomena, and to support teachers in facilitating this process. Using evidence and reasoning to construct explanations is one of the most important practices students can learn, with application beyond science class to high school, college, career, and citizenship readiness in all areas!

This document charts the alignment between IQWST® lessons and the Next Generation Science Standards' (NGSS) performance expectations with which they most highly correlate.
It is important to note that no single activity should be thought of as meeting an NGSS performance expectation (PE). Meeting a PE requires carefully sequenced activities, investigations, readings, discussions, and lessons that support students in building understanding of a disciplinary core idea, crosscutting concept, and the multiple scientific practices involved in “making sense” of complex ideas.
In contrast to the old practice of checking off a standard as “met” because it was taught on a given day, new standards demand a very different approach.

These assessments integrate into IQWST classrooms, and are appropriate for use with all students, using engaging multi-media content to greatly reduce accessibility-barriers for English learners and other students who struggle with language-heavy traditional tests. ONPAR is designed using the latest college and career readiness standards, including the Common Core State Standards for Mathematics, Next Generation Science Standards, and Framework for K-12 Science Education.
