Science Standards

The Vision for Science Instruction

Science, engineering, and technology permeates nearly every facet of modern life, and they also hold the key to meeting many of humanity's most pressing current and future challenges. Yet too few US people have a strong background in these fields, and many people lack even fundamental knowledge of them. This national trend has created a widespread call for change in science education, hence the new vision for science instruction.

DoDEA Science Standards

The research-based science standards set the expectations for what students should know and be able to do. These standards give educators the opportunity to provide classroom learning experiences that stimulate students’ interests in science and prepares them for college, careers, and citizenship.

How do I know the FOSS Resources align to the DoDEA's College and Career Ready Standards?

Answer: The FOSS program was designed for the Next Generation Science Standards, which are DoDEA’s College and Career Ready Standards for Science (CCRSS). The three dimensions of the standards are highlighted throughout the Investigation Guide. Science and Engineering Practices are always blue, Crosscutting Concepts are always green, and Disciplinary Core Ideas are always orange. Look at the Framework and NGSS section for more information about instruction and look at the Assessment section for information about how to evaluate student progress on the standards. Each investigation builds upon the previous one and the grade levels build upon one another. It is important to proceed through the investigation as designed to avoid creating any gaps in student knowledge. Any similarities in activities in different grade levels in an intentional part of the program to allow students to utilize prior knowledge as they explore the concepts with greater depth.

Science Standards: Science & Engineering Practices, Crosscutting Concepts, and Disciplinary Core Ideas

Within the Next Generation Science Standards (NGSS), there are three distinct and equally important dimensions to learning science: Science and Engineering Practices, Crosscutting Concepts, and Disciplinary Core Ideas. The first dimension, Science and Engineering Practices, describes what scientists do to investigate the natural world and what engineers do to design and build systems. The second dimension, Crosscutting Concepts, helps students explore connections across the four domains of science, including Physical Science, Life Science, Earth and Space Science, and Engineering Design. The third dimension, Disciplinary Core Ideas, includes the key ideas in science that have broad importance within or across multiple science or engineering disciplines. These dimensions are combined to form each standard—or performance expectation—and each dimension works with the other two to help students build a cohesive understanding of science over time. The Science Standards are not a set of daily standards, but a set of expectations for what students should be able to do by the end of instruction.

Science & Engineering Practices

The practices are what students DO to make sense of phenomena. They are both a set of skills and a set of knowledge to be internalized. The SEPs reflect the major practices that scientists and engineers use to investigate the world and design and build systems.


Science and Engineering Practices are the focus NOT Scientific Method

Crosscutting Concepts in FOSS

Grades K-5

Using Crosscutting Concepts to Prompt Student Responses

Crosscutting concepts are essential tools for teaching and learning science because students can understand the natural world by using crosscutting concepts to make sense of phenomena across the science disciplines.

Prompts that Promote Rigorous Discussions

Examples: What does the pattern of data you see allow you to conclude from the experiment?

What caused the patterns you observed?

What things stay the same in the system presented in the scenario?

Student Performance Expectations

The Performance Expectations set the learning goals for students, but do not describe how students get there. Performance Expectations offer a benchmarked guideline for what a student should know, but they can’t be understood in a vacuum. The Performance Expectations outlined in the standards depend on the three dimensions of the science framework. Understanding how the standards are organized is fundamental to their successful implementation.
