1. Circulatory system—structure of heart and blood vessels (arteries, veins), function of blood (oxygen transport), double circulation explanation
2. Physical properties—melting/boiling points, electrical conductivity, state changes (e.g. oxygen boiling), temperature comparisons to determine state
3. Light and reflection—ray diagrams using mirrors in a periscope, understanding and naming the reflection process
4. Rock cycle—identifying processes (e.g. erosion, melting, heat/pressure), transformation between rock types: sedimentary, metamorphic, igneous
5. Microorganisms and disease—disease prevention in rainforest (e.g. insect bites), types of infectious organisms (e.g. viruses, fungi)
6. Dissolving investigation—effect of temperature on solubility, prediction based on particle model, equipment use, dependent variable identification
