Grade 4 Science Practice

Students analyze evidence of landscape change from water, ice, wind, living things, and sudden events.

Prongo-owned

Students classify rock types, describe the rock cycle, and review weathering, erosion, and deposition.

Prongo-owned

Students explore kinetic and potential energy, relate speed to motion energy, and trace transfer and conversion in everyday systems.

Prongo-owned

Students test prototypes, identify failure points, and optimize solutions through iterative redesign.

Prongo-owned

Students explore reflection, classify materials by how they interact with light, and build a simple model of vision.

Prongo-owned

Students classify natural and energy resources, compare renewable and nonrenewable options, and analyze tradeoffs.

Prongo-owned

Students relate plant and animal structures to growth, survival, behavior, and reproduction.

Prongo-owned

Students develop and revise models, write evidence-based arguments with reasoning, and communicate findings.

Prongo-owned

Students explore waves as repeating patterns, label amplitude and wavelength, and connect waves to energy transfer in water and sound.

Prongo-owned

Students explore how animals use senses to gather information and how signals transfer information for survival, communication, and response.

Prongo-owned

Students review and extend ecosystem ideas—roles, energy flow, and interactions—among living and nonliving parts of environments.

Prongo-owned

Students investigate how kinetic energy transfers when objects collide, relating speed and mass to changes in motion after impact.

Prongo-owned

Students deepen understanding of natural hazards and explore how communities design solutions—engineering, nature-based, and preparedness—to reduce harm.

Prongo-owned

Students review Earth–Moon–Sun patterns, explaining day/night and seasonal sunlight with models and evidence.

Prongo-owned

Students evaluate human impacts on resources and ecosystems and recommend evidence-based stewardship plans.
