1. Human digestion: organ identification (mouth, oesophagus, stomach, intestines), stomach function, food breakdown
2. Dissolving: balance and measuring cylinder use, solute vs. solvent, solution definition, salt recovery by evaporation
3. Forces on ship: applied force, gravity, water resistance, air resistance, friction, upthrust identification
4. Water properties and evaporation: boiling/melting point mismatch, evaporation speed vs. temperature, control variables, data table interpretation
5. Magnetism: magnetic materials, bar chart of paperclip count, experimental limitation due to tie in results, suggestion to repeat for accuracy
6. Earth and space: seasonal change by Earth tilt, orbit direction = anticlockwise, orbit time = 365 days, orbit shape = ellipse
