**Day and Night:** Earth rotates while Sun stays still. Side facing Sun = day, side away from Sun = night.
**Seasons:** 4 seasons repeat every year — April-June (hot/dry), July-September (rainy), October-December (cool), January-March (mild).
**Globe:** A ball-shaped model of Earth. Blue = oceans and seas (3/4 of Earth). Green/brown = land.
**Observations to Track:** Plant life (blooming, shedding), birds and animals (arrival, departure), air and heat (temperature), water and water bodies (flooding, drying), human activities (farming, festivals).
**Key Fact:** Dong in Arunachal Pradesh sees India's first sunrise each day.
**Diagrams to Remember:** Torch shining on rotating globe showing day-night cycle. Seasons chart showing 4 time periods with changes in nature.
**Don't Confuse:** Sun is NOT moving across the sky — Earth is rotating. All parts of Earth do NOT have same season at same time. Changes happen in patterns that repeat.
