1. Biology—plant reproduction (pollination, fertilisation, seed dispersal), classification of organisms, vertebrate/invertebrate traits, food chains and energy flow, adaptation for survival 2. Chemistry—states of matter, melting/boiling points, particle models, diffusion, mixtures vs compounds, reversible and irreversible changes, heating curves 3. Physics—forces (balanced/unbalanced), friction, speed = distance/time, Newton meter usage, light behavior (reflection, shadows), sound travel and hearing ranges, basic circuits 4. Earth Science—rock types (igneous, sedimentary), fossil formation, acid rain effect, bioindicators (lichens), weathering and erosion, fossil fuel alternatives 5. Scientific method—experiment design, variable identification, safe procedure, equipment reading (thermometer, ammeter), fair testing, pattern recognition
