Grade 3 Science Practice

Students explore how physical and behavioral adaptations help organisms survive in deserts, Arctic, oceans, and other habitats.

Prongo-owned

Students build food webs, classify organism roles, and trace energy flow from the sun through ecosystems.

Prongo-owned

Students apply the engineering design cycle with clear criteria and constraints, testing and improving prototypes.

Prongo-owned

Students investigate balanced and unbalanced forces, predict motion changes, and explore friction, gravity, and magnetism.

Prongo-owned

Students compare life cycles, distinguish inherited from acquired traits, and explore variation and metamorphosis.

Prongo-owned

Students explore how environmental changes affect organisms, predict impacts, and consider conservation solutions.

Prongo-owned

Students build claim-evidence-reasoning arguments, evaluate evidence quality, and communicate findings clearly.

Prongo-owned

Students differentiate daily weather from long-term climate, explore climate zones, and use data to describe regional patterns.

Prongo-owned

Students study where Earth's water is found, how the water cycle works, and how water shapes landforms through weathering, erosion, and deposition.

Prongo-owned

Students learn what fossils are, how they form, and how body and trace fossils provide evidence about organisms and environments from long ago.

Prongo-owned

Students explore magnetic poles, materials, simple circuits, electromagnets, and static electricity with a focus on safe hands-on investigation.

Prongo-owned

Students review and extend ideas about matter, properties, states, and physical changes with measurement and classification practice.

Prongo-owned

Students learn about natural hazards, how communities prepare and respond, and solutions that reduce harm through planning, engineering, and nature-based ideas.

Prongo-owned

Students build an introductory concept of energy using everyday examples of heat, light, sound, and motion.

Prongo-owned

Students evaluate human impacts and recommend age-safe stewardship actions supported by reasons and simple evidence.
