1. Life processes and human biology: chimpanzee respiratory system, gas exchange (oxygen), food safety, human immune system, infectious diseases, bacteria growth and spread, heart rate investigation

2. Physical changes and states of matter: melting, boiling point (100°C), dissolving solids in liquids, particle models of solids/liquids/gases, compression of gases, diffusion

3. Energy and physical sciences: thermal conductivity comparison, light refraction using angles, angle prediction via interpolation, electric circuits (parallel vs series), heat conduction, force and motion (baseball collision effects)

4. Earth and space sciences: rock cycle processes (sedimentation, erosion, pressure, metamorphism), solar system model distances, Earth-Moon scale, rotation/orbit implications

5. Scientific skills and data handling: line graph plotting, reading measuring scale (height), interpreting tables (bacteria growth, conductivity, planet distances), classification and enquiry types (observation, research, pattern seeking), circuit drawing, experimental variables
