WA 3rd Grade Science Curriculum
Give your child the science support they need to succeed. StudyPug covers every 3rd grade topic Washington schools teach, from food chains and adaptations to simple machines and Earth materials.
About 3rd Grade Washington science
Washington State follows the Washington State K-12 Science Learning Standards, which are aligned to the Next Generation Science Standards and organized around phenomena-driven, three-dimensional learning. In 3rd grade, students explore ecosystems and food chains, adaptations, forces and simple machines, thermal energy, landforms, Earth materials, and the solar system. StudyPug provides video lessons, practice problems, and step-by-step solutions for every one of these strands so students can build confidence between school sessions.
- Strands covered: Ecosystems, Adaptations, Food Chains, Energy Pyramids, Forces, Simple Machines, Thermal Energy, Landforms, Earth Materials, Solar System, Human Impact, Climate, and Engineering Process
- Video lessons taught by certified teachers for every 3rd grade science topic
- Practice problems with instant feedback and step-by-step video solutions
- Fully aligned to Washington State K-12 Science Learning Standards (NGSS-adopted)

Washington 3rd Grade Science Topics
- Ecosystems and Food Chains: Students examine how living things interact in ecosystems, trace energy through food chains, and explore energy pyramids to understand feeding relationships.
- Adaptations: Lessons focus on how plant and animal adaptations help organisms survive in their environments.
- Forces and Simple Machines: Students investigate pushes, pulls, and the six simple machines, connecting force concepts to real-world engineering.
- Thermal Energy: Lessons cover how heat moves between objects and how temperature changes affect materials.
- Landforms and Earth Materials: Students identify major landforms and learn how rocks, soil, and other Earth materials are formed and used.
- Solar System: Lessons introduce the planets, the sun, and patterns of day, night, and seasons.
- Human Impact and Climate: Students explore how human activities affect the environment and how climate varies across regions.
- Engineering Process and Traditional Practices: The engineering design process is taught alongside indigenous traditional practices, connecting science to culture and community problem-solving.
How StudyPug Helps Washington 3rd Grade Science Students
When a student gets stuck on a concept like food chains or how simple machines reduce effort, StudyPug provides a short video lesson that breaks the idea down step by step, followed by practice problems with instant feedback. For a full overview of what students cover in this course, visit our grade 3 science help page. Students who want to see where this year fits in the bigger picture can also browse the wa grade 4 science curriculum to understand what comes next.
Parents can monitor progress, assign specific topics, and use parent assignment tools to focus practice on the strands that need the most attention - all without needing a science background themselves.
Aligned to Washington 3rd Grade Science Curriculum
Every lesson and practice problem on StudyPug is built to match the Washington State K-12 Science Learning Standards, which are adopted from the Next Generation Science Standards. That means the vocabulary, the concepts, and the order of topics reflect exactly what Washington 3rd grade classrooms teach - so nothing your child studies here will contradict what they hear in school.
