1. Life processes and reproduction: seeds for reproduction, other processes include movement, nutrition, respiration 2. Mixtures and solutions: sugar dissolves in water to form a solution, total mass = 110 g, mass measured using a balance 3. Forces and friction: identifying friction force direction, material with longest slide time has most friction, friction slows movement 4. Classification of materials and animals: iron as metal, rocks provide materials like gold and copper, animal grouping by feathers, fur, legs 5. Separation methods: filtering sea water separates sand, evaporation for salt, sand is insoluble, magnetic separation for steel–copper mixture 6. Light and shadows: sorting objects by transparency using light passage, shadows longest early/late in day due to Sun’s angle, length measured in cm
