Grade 2 Science Practice

Students explore biodiversity in different habitats, match species to environments, and discuss why protecting habitats matters.

Prongo-owned

Students investigate how wind and water erode and weather land, sorting fast events like floods from slow changes like river canyons.

Prongo-owned

Students follow the engineering design cycle — define, design, test, and improve — on classroom challenges with criteria and constraints.

Prongo-owned

Students explore pushes, pulls, friction, gravity, and magnetic forces through rolling, sliding, and magnet tests.

Prongo-owned

Students compare plant and animal life cycles, learn metamorphosis through butterflies and frogs, and sequence stages from egg or seed to adult.

Prongo-owned

Students classify and test material properties like flexibility, absorbency, and strength, then match materials to purposes in simple design tasks.

Prongo-owned

Students plan simple investigations, make testable predictions, collect and chart data, and share evidence-based conclusions.

Prongo-owned

Students learn the water cycle stages — evaporation, condensation, precipitation, and collection — and connect them to weather and everyday observations.

Prongo-owned

Students explore how heating and cooling change materials through melting, freezing, evaporating, and condensing, including reversible and hard-to-reverse examples.

Prongo-owned

Students explore how people affect environments, practice conservation ideas including the three Rs, and plan positive actions for habitats and resources.

Prongo-owned

Students learn how pollinators help flowers make seeds and how seeds travel to new places by wind, water, and animals.

Prongo-owned

Students explore sound as vibration and light as energy for seeing, including shadows, reflection, transparent vs opaque materials, and safety.

Prongo-owned

Students distinguish everyday weather from long-term climate patterns, practice sorting examples, and use journals and forecasts.

Prongo-owned

Students learn how bones and muscles support movement, meet the heart at intro level, and practice inclusive healthy habits.

Prongo-owned

Students observe sun/moon patterns, day/night cycles, seasonal daylight awareness, and safe sky study habits.
