Grade 3 Science: Forces, Life, Weather & Earth

This complete Grade 3 science course guides learners through physical, life, and Earth science in 24 interactive, teacher-led lessons. Students explore forces and motion, including pushes and pulls, balanced and unbalanced forces, friction, gravity, magnetic forces, and patterns used to predict movement. Life science units cover plant and animal life cycles, inherited traits, variation within species, structural and behavioral adaptations, habitats, group behavior, and how environmental change affects survival. Learners investigate fossils to understand how fossil evidence reveals past organisms and environments. Earth science units introduce weather elements, measurement tools, weather patterns and forecasting, climate regions, natural hazards, and ways communities reduce the effects of hazardous events. Lessons use visuals, guided discussion, experiments, simulations, games, and hands-on activities to build observation, prediction, and critical thinking skills. Activities are designed to make scientific ideas accessible and engaging for third graders while encouraging curiosity, explanation, and evidence-based reasoning. The course follows a logical Grade 3 progression and aligns with commonly taught U.S. Grade 3 science concepts and NGSS-connected topics. This curriculum works well for homeschooling families or small-group classrooms seeking a structured, standards-aligned online science program.
