Grade 9 Science Standards in Arkansas, Simplified

We understand that academic standards form the foundation of your curriculum. These guidelines define student learning objectives, and translating them into daily instruction is a significant part of your work. Our goal is to provide resources that make this process clearer and more manageable, supporting your expertise in the classroom.

Academic standards are learning goals that outline what students are expected to know and be able to do in each subject by the end of a grade level. For teachers, they provide a consistent framework for instruction without dictating specific teaching methods or materials. For example, Arkansas's Grade 9 Physical Science standards require students to learn about matter and its interactions, motion, and energy, giving educators clear targets for their lesson plans.

What Are Grade 9 Science Standards in Arkansas?

In Grade 9, Arkansas uses the K-12 Science Standards, which are aligned with the Next Generation Science Standards (NGSS). Most students take Physical Science, which integrates concepts from multiple scientific fields to provide a comprehensive foundation.

The Grade 9 standards for Physical Science are organized into the following domains:

• Physical Science (PS):
  • HS-PS1: Matter and Its Interactions
    • Atomic structure, periodic table, chemical bonding, chemical reactions, conservation of mass
  • HS-PS2: Motion and Stability: Forces and Interactions
    • Newton’s laws, gravitational and electromagnetic forces, relationships between force, mass, and acceleration
  • HS-PS3: Energy
    • Energy transfer, conservation of energy, kinetic/potential energy relationships, and energy in systems
  • HS-PS4: Waves and Their Applications
    • Wave properties, electromagnetic waves, and how waves transfer energy and information
• Earth and Space Science (ESS):
  • HS-ESS1: Earth’s Place in the Universe
    • Solar system scale, formation of the universe, and star life cycles
  • HS-ESS2: Earth’s Systems
    • Plate tectonics, the rock cycle, and the water cycle
• Engineering Design (ETS):
  • HS-ETS1: Engineering Design
    • Define problems, design solutions, and evaluate designs based on constraints (cost, safety, impact)

The framework for these standards is guided by the Next Generation Science Standards and the Arkansas Division of Elementary and Secondary Education.

Key Tested Standards

For Grade 9 Science in Arkansas, assessments typically focus on foundational concepts in Physical Science, Life Science, and Earth and Space Science. These standards are designed to build critical skills for upper-level coursework, and the likely tested standards include:

Physical Science (PS)

• HS-PS1-1: Use models to explain the structure of atoms and how particles interact.
• HS-PS1-4: Conduct experiments to show how energy is absorbed or released during chemical reactions.
• HS-PS2-1: Analyze data to explain how forces influence the motion of objects and systems.
• HS-PS3-1: Develop models to demonstrate energy transfer and conservation.

Life Science (LS)

• HS-LS1-1: Explain how cellular systems work together to perform life processes.
• HS-LS2-1: Use models to describe how energy flows and matter cycles in ecosystems.
• HS-LS3-1: Explain how DNA and genetic variations influence inheritance.
• HS-LS4-4: Construct explanations for how natural selection results in species adaptations.

Earth and Space Science (ESS)

• HS-ESS1-3: Analyze and interpret data to determine the scale properties of objects in the solar system.
• HS-ESS2-1: Model how Earth's internal and surface processes interact (e.g., plate tectonics).
• HS-ESS3-1: Assess solutions for managing natural resources and minimizing environmental impacts.

These standards focus on modeling, analyzing data, conducting investigations, and solving real-world problems, all of which are critical for assessments. This information is based on guidance from the Next Generation Science Standards and the Arkansas Division of Elementary and Secondary Education.

Example Learning Objectives for Unit Planning

Learning objectives translate broad standards into clear, student-focused goals for each lesson. They define what students should be able to do by the end of a class, making progress measurable for both you and them. To illustrate, here are examples of learning objectives for two Grade 9 Science standards:

HS-PS1-4 (Energy in chemical reactions)

1. I can conduct experiments to observe whether energy is absorbed (endothermic) or released (exothermic) during chemical reactions.
2. I can use data from experiments to determine whether a reaction involves a change in energy.
3. I can explain how energy changes in a chemical reaction are related to the breaking and forming of chemical bonds.

HS-LS2-1 (Energy flow and matter cycling in ecosystems)

1. I can identify the roles of producers, consumers, and decomposers in the flow of energy in an ecosystem.
2. I can use a model (e.g., food web or energy pyramid) to describe how energy flows and matter cycles through an ecosystem.
3. I can explain how changes in one part of an ecosystem affect the energy and matter in other parts of the system.

Key Changes & Updates

The Grade 9 Science Standards were updated in 2015 to align with the Next Generation Science Standards (NGSS). This update introduced a more hands-on, inquiry-based approach to science education, focusing on three-dimensional learning. The goal is to help you engage students with real-world applications and phenomena, moving instruction from abstract concepts to practical problem-solving.

This framework integrates Science and Engineering Practices (what students do), Crosscutting Concepts (themes like cause and effect), and Disciplinary Core Ideas (content knowledge). As a result, performance expectations are more hands-on. Students are now asked to demonstrate understanding by conducting investigations, building models, and analyzing data. The standards also incorporate engineering design principles and place a greater emphasis on systems thinking to better prepare students for future challenges.
