1. Earth and space science: Earth’s orbit direction, elliptical shape, 365-day revolution, atmospheric gases (oxygen, nitrogen)
2. Human biology and health: digestive system parts (mouth, stomach, intestines), balanced diet importance
3. Forces and motion: balanced/unbalanced forces, floating boat dynamics, effect of unequal forces
4. States of matter: particle model for solids/liquids/gases, compression, shape, flow, condensation process
5. Adaptations and environment: structural features (spines, fur, ears, leaves), seasonal effects from axial tilt, seed dispersal by wind, water, animals
6. Practical investigations: magnetic strength (distance measurement), ramp force experiment (independent variable, graph plotting, pattern recognition), dissolving quiz (solvent, solution, mixture), separating dissolved solids, sound pitch analysis, force and loudness of gong
