NGSS Active Physics Alignment

NGSS “Next Generation Science Standards (NGSS) identifies the science all K-12 students should know. These new standards are based on the National Research Council’s A Framework for K-12 Science Education. The National Research Council, the National Science Teachers Association, the American Association for the Advancement of Science, and Achieve have partnered to create the standards through a collaborative state-led process. The standards are rich in content and practice and arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education.”1

“The National Research Council's (NRC) Framework describes a vision of what it means to be proficient in science; it rests on a view of science as both a body of knowledge and an evidence-based, model and theory building enterprise that continually extends, refines, and revises knowledge. It presents three dimensions that will be combined to form each standard:

Dimension 1: Practices

The practices describe behaviors that scientists engage in as they investigate and build models and theories about the natural world and the key set of engineering practices that engineers use as they design and build models and systems. The NRC uses the term practices instead of a term like “skills” to emphasize that engaging in scientific investigation requires not only skill but also knowledge that is specific to each practice. Part of the NRC’s intent is to better explain and extend what is meant by “inquiry” in science and the range of cognitive, social, and physical practices that it requires.

Although engineering design is similar to scientific inquiry, there are significant differences. For example, scientific inquiry involves the formulation of a question that can be answered through investigation, while engineering design involves the formulation of a problem that can be solved through design. Strengthening the engineering aspects of the Next Generation Science Standards will clarify for students the relevance of science, technology, engineering and mathematics (the four STEM fields) to everyday life.

Dimension 2: Crosscutting Concepts

Crosscutting concepts have application across all domains of science. As such, they are a way of linking the different domains of science. They include: Patterns, similarity, and diversity; Cause and effect; Scale, proportion and quantity; Systems and system models; Energy and matter; Structure and function; Stability and change. The Framework emphasizes that these concepts need to be made explicit for students because they provide an organizational schema for interrelating knowledge from various science fields into a coherent and scientifically-based view of the world.

Dimension 3: Disciplinary Core Ideas

Disciplinary core ideas have the power to focus K–12 science curriculum, instruction and assessments on the most important aspects of science. To be considered core, the ideas should meet at least two of the following criteria and ideally all four:

1http://www.nap.edu/catalog/18290/next-generation-science-standards-for-states-by-states


• Have broad importance across multiple sciences or engineering disciplines or be a key organizing concept of a single discipline;

• Provide a key tool for understanding or investigating more complex ideas and solving problems;

• Relate to the interests and life experiences of students or be connected to societal or personal concerns that require scientific or technological knowledge;

• Be teachable and learnable over multiple grades at increasing levels of depth and sophistication.”2

Alignment between Active Physics and Next Generation Science Standards (NGSS) Reminder: NGSS is not a curriculum. It is up to curriculum developers to create engaging, pedagogically sound means of approaching physics using research and strong instructional models which will guide students to an understanding of physics. The students should then have the knowledge and context to meet the Performance Expectations of the NGSS as well as have a sense of physics as a coherent discipline and a way of viewing the world.

“Active Physics® is a curriculum based on the research on how students learn—encapsulated in the 7E Instructional Model (elicit, engage, explore, explain, elaborate, extend, evaluate). As a result, Active Physics provides ALL students with a deep and memorable learning experience.”3

This document shows the alignment between Active Physics and the Next Generation Science Standards to help teachers get a better understanding of the relationship between them.

The NGSS are typically organized by Disciplinary Core Idea (DCI), and each DCI contains several Performance Expectations, or things students should know or be able to do after their science courses. Each Performance Expectation has an identifying code that includes the grade and strand (Earth Science, Life Science, Physical Science, or Engineering), such as HS-PS3-1.

There are nine parts to this document, one for each Chapter of Active Physics. Each part contains a Lead Page for the chapter with a table showing the alignment between those sections of Active Physics and the NGSS. This alignment was determined by Professor Arthur Eisenkraft, Active Physics author and former NSTA president. Within each part, you will find tables for the alignment of the sections and NGSS. After the Lead Page for that chapter, you will find a series of tables that describe the activity and then show which Crosscutting Concepts and Science and Engineering Practices are utilized in that activity, listed numerically.

A second document contains the alignment listed by Disciplinary Core Idea/Performance Expectation, rather than by chapter.

An example lead page

After that “Lead Page”, there is a page for each section listed in the table.

Each page has a table that includes the Crosscutting Concepts and Science and Engineering Practices relevant to that section marked in red. On the left of those tables, there is a box listing the Performance Expectation it aligns to. When a section aligns with two different Performance Expectations, this is noted in red at the top of the page.


An example section page

Essential Questions in Active Physics The Essential Questions are included on this page because they are one way to assess the Performance Expectations.

What does it mean? NGSS: This most closely aligns with the Disciplinary Core Ideas in NGSS. The first essential question, “What does it mean?” requires students to describe the content of the section based on what they have learned in their investigation and reading. How do you know? NGSS: The question asks students to draw the connection between the Disciplinary Core Idea and the Science and Engineering Practices. The second essential question, “How do you know?” is answered by a description of the experimental evidence that students discovered during the Investigate. Students “know” because they have done an experiment. These experiments utilize the Science and Engineering Practices highlighted in red in the Section Charts.


Why do you believe? NGSS: This question asks students to draw connections between the content of the Section and the larger Disciplinary Core Idea. [i.e. Connects with Other Physics Content] It then draws connections between the Disciplinary Core Ideas and the Crosscutting Concepts. [i.e. Fits with Big Ideas in Science] It finally connects the Disciplinary Core Idea, the Science and Engineering Practice and the Crosscutting Concept (three-dimensional learning) in exploring the “nature of science.” [i.e. Meets Physics Requirements.] The third essential question, “Why do you believe?” emphasizes one of three ideas (“Connects with Other Physics Content”, “Fits with Big Ideas in Science,” or “Meetings Physics Requirements”) to help students understand physics as it relates to the world outside the classroom. Why should you care? NGSS: This question is a response to students about relevance and students’ very common and appropriate question, “Why are we learning this?” It focuses on the engineering applications of the physics content. The NRC Framework (from which the NGSS was drawn) states: “Specifically, a core idea for K-12 science instruction should

1. Have broad importance across multiple sciences or engineering disciplines or be a key organizing principle of a single discipline.

2. Provide a key tool for understanding or investigating more complex ideas and solving problems.

3. Relate to the interests and life experiences of students or be connected to societal or personal concerns that require scientific or technological knowledge.

4. Be teachable and learnable over multiple grades at increasing levels of depth and sophistication. That is, the idea can be made accessible to younger students but is broad enough to sustain continued investigation over years. “4

Why should you care deals specifically with #3 and indirectly with #1 and #2. The last question, “Why Should You Care?” requires students to make a direct line from the section to the Chapter Challenge. This serves three purposes: the students have an immediate need to know this information, they are required to transfer their new knowledge and also to begin planning a response to the Chapter Challenge. Since the Chapter Challenges all deal with engineering, the “Why do you care” essential questions also links Engineering Practices required for the chapter completion to each individual Section of the chapter.

You will find tables at the end of the document that show the alignment by Performance Expectation and by Active Physics Chapter.

Chapter 1: Driving the Roads Lead Page

Chapter 1 does not directly address any of the Performance Expectations in the Next Generation Science Standards. However, it is still a valuable (and vital) chapter to complete with your students because it helps to build a foundation for more complex physics content. Asking why you should teach a chapter (or section) when the content is not in the NGSS is akin to your students asking if they need to know something even though it won’t be on the test. (For example, the concept of velocity is not included as a Performance Expectation in the high school Next Generation Science Standards, but there are very few, if any, physics teachers who would say that you shouldn’t teach velocity.)
