We understand that working with state standards can be a detailed process. Our goal is to provide clear, practical resources to support you in your planning and instruction. Here, we will look at what education standards are and how they function in the classroom, using a specific set of science standards as an example.
Education standards are learning goals that outline what students should know by the end of a grade level. For teachers, they provide a framework for instruction without dictating specific teaching methods. For example, the Grade 8 Science Standards in California specify that students should be able to apply Newton’s Third Law, but you decide on the best activities and lessons to teach that concept.
What Are Grade 8 Science Standards in California?
The Grade 8 Science Standards for California are built on the California Next Generation Science Standards (CA NGSS). They are organized into four key areas of study to give you a clear roadmap for instruction.
Here are the key areas and standards for Grade 8 Science:
1. Physical Science (PS): Forces, Motion, and Energy
PS2: Motion and Stability
Key Standard (MS-PS2-1): Apply Newton’s Third Law to design solutions to a problem involving the motion of colliding objects.
Key Standard (MS-PS2-2): Plan and conduct investigations to provide evidence of the effects of forces, including gravity, on the motion of objects.
Key Standard (MS-PS2-4): Construct and present arguments using evidence to explain how gravitational interactions depend on the mass of objects and the distance between them.
PS3: Energy
Key Standard (MS-PS3-5): Construct, use, and present arguments to support the claim that when the motion energy of an object changes, energy is transferred to or from the object.
2. Life Science (LS): Natural Selection and Adaptations
LS4: Biological Evolution: Unity and Diversity
Key Standard (MS-LS4-1): Analyze and interpret data for patterns in the fossil record to document the existence, diversity, and extinction of life forms throughout Earth’s history.
Key Standard (MS-LS4-2): Construct an explanation based on evidence that anatomical similarities and differences among organisms can indicate evolutionary relationships.
Key Standard (MS-LS4-4): Construct an argument using evidence to explain how changes in the environment affect the survival of organisms.
3. Earth Science (ESS): Space, History of Earth, and Human Impact
ESS1: Earth’s Place in the Universe
Key Standard (MS-ESS1-1): Develop and use a model of the Earth-Sun-Moon system to describe lunar phases, eclipses, and seasons.
Key Standard (MS-ESS1-2): Develop and use a model to explain the role of gravity in the motions within galaxies and the solar system.
ESS3: Earth and Human Activity
Key Standard (MS-ESS3-3): Design a method for monitoring and minimizing human impact on the environment.
Key Standard (MS-ESS3-4): Construct an argument supported by evidence for how increases in human population and consumption of natural resources impact Earth’s systems.
4. Engineering, Technology, and Applications of Science (ETS): Problem Solving
ETS1: Engineering Design
Key Standard (MS-ETS1-1): Define criteria and constraints of a design problem related to minimizing environmental impact and evaluate competing solutions.
Key Standard (MS-ETS1-4): Develop and test models to optimize a design solution to a problem (e.g., renewable energy projects).
The framework for these standards is guided by the Next Generation Science Standards and resources from the California Department of Education.

Key Crosscutting Concepts (CCCs):
Cause and Effect: Understanding how forces or environmental changes cause observable effects
Systems and Models: Exploring systems like the solar system, ecosystems, or forces and motion
Energy and Matter: Analyzing how energy is transferred in systems, such as collisions or energy transformations
Why These Standards Are Key for Testing:
Students are assessed on their ability to:
Develop and Use Models: For example, modeling the Earth-Sun-Moon system or forces acting on objects.
Conduct Investigations: For example, testing Newton’s Laws or energy transfer in motion.
Analyze and Interpret Data: For example, analyzing fossil records or force and motion data.
Construct Evidence-Based Explanations: For example, explaining evolutionary relationships or the environmental impact of human activities.

Example Learning Objectives for Unit Planning
Learning objectives break down broad standards into specific, student-centered goals. They clarify what students should be able to do after a lesson, guiding both your instruction and their learning path. Here are examples for two Grade 8 Science standards, written in student-friendly language to align with the NGSS three-dimensional learning approach.
Standard: MS-PS2-2
Plan and conduct an investigation to provide evidence that balanced and unbalanced forces affect the motion of an object.
Learning Objectives:
I can explain the difference between balanced and unbalanced forces and how they affect an object’s motion.
I can design and carry out an experiment to test how different forces (e.g., pushes, pulls, friction) affect the movement of an object.
I can record data about how an object’s speed or direction changes when forces act on it.
I can use my experimental results to explain how balanced forces keep an object steady and unbalanced forces cause movement.
Standard: MS-LS4-1
Analyze and interpret data for patterns in the fossil record to document the existence, diversity, extinction, and change of life forms throughout Earth’s history.
Learning Objectives:
I can explain what a fossil record is and how scientists use it to study life on Earth.
I can analyze fossil data to identify patterns, such as when organisms appeared, evolved, or went extinct.
I can describe how the fossil record shows that Earth’s environments and life forms have changed over time.
I can use evidence from fossils to explain how life on Earth has become more diverse over millions of years.
Key Changes & Updates
The Grade 8 Science Standards saw a significant update with the 2013 adoption of the California Next Generation Science Standards (CA NGSS). This change moved instruction away from fact memorization and toward a more active, three-dimensional learning model. The approach combines what students do (Science and Engineering Practices), how they think across disciplines (Crosscutting Concepts), and what they know (Disciplinary Core Ideas). The goal is to help students build a deeper understanding of science through hands-on exploration and inquiry.
In practice, these updates mean your lessons can be built around real-world phenomena, making science more relatable for students. There is a greater focus on integrating engineering design, which encourages problem-solving and creative thinking. Instead of just learning facts, students are now expected to conduct investigations, analyze data, and construct evidence-based arguments. This shift helps build critical thinking skills and prepares students for future studies and careers in science and technology fields.
