1. Biology—plant reproduction (pollination, fertilisation), seed dispersal mechanisms, food chains, adaptations for survival, vertebrates vs invertebrates, classification criteria
2. Chemistry—states of matter, particle arrangement, changes of state (melting, evaporation), mixtures vs compounds, diffusion, reversible/irreversible changes, boiling point comparison
3. Physics—forces and motion, Newton meter readings, friction and air resistance, speed calculation, shadow formation and light travel, simple electric circuits
4. Earth Science—rock types (sedimentary, igneous), fossil formation process, erosion and weathering, fossil fuel use vs renewables, bioindicators (lichens)
5. Scientific method—safe experimental setup, variable identification, thermometer usage, circuit diagram interpretation, pattern analysis
