1. Biology: blood cell function and infection indicators (WBC increase), plasma transport and role, respiration organ system analogy (lungs/diaphragm model), nutrient energy sources (fat), ecosystems and habitat identification, squirrel competition and area changes. 2. Chemistry: chromatography (separation, color analysis), exothermic reactions, purity calculation (mass percentage), solubility-temperature relation, metal reactions (observations, word equations), metal reactivity and salt production. 3. Physics: reflection and refraction (ray identification), law of reflection, light dispersion through glass (wavelength/speed), distance-time graph interpretation (speed, acceleration, stationary), electromagnetic field direction and Earth’s magnetism. 4. Energy and environment: electricity generation pie chart analysis, fossil fuel identification, renewable resource listing (e.g., solar, wind), galaxy structure (stars, planets), telescope usage in astronomy. 5. Experimental science: fair testing (mass control, same conditions), electromagnetic coil strength factors (turns, prediction validation), magnetic pole interactions, pressure explanation via particle motion, solubility graph plotting and trend description.
