Chemistry
Investigate and compare how the solubilities, in water, of (a) potassium chloride and (b) sodium carbonate (anhydrous) change with temperature.
Physics
Investigate and compare how the rates of flow of powdered or granulated solids through a funnel are affected by (a) the size of the solid particles and (b) any one of the funnel dimensions.

Biology
Compare by means of investigation the vitamin C content of a number of commercial and fresh fruit juices.
Chemistry
Compare by means of investigation methanol, propan-1-ol and candle wax in terms of their effectiveness as fuels.
Physics
Investigate any two factors that affect the output from a solar cell when light is shone on it.

Biology
Investigate named seeds, chosen by you, to examine the effects of (a) placing the seeds in a fridge for a few days before sowing, (b) placing the seeds in a hot press for a few days before sowing on (i) the percentage of seeds that germinate, (ii) the speed of germination of the seeds.
Chemistry
Investigate the effects on the amount of carbon dioxide dissolved in a fizzy drink when it is stored in (a) an open container (b) a closed container, at different conditions of (i) temperature (ii) stirring or shaking (iii) time elapsed.
Physics
Investigate the factors that determine the rate at which heat is lost from different types of drinking cups that contain hot liquid.
2011
Biology
Carry out an investigation to study the anaerobic respiration of yeast with particular reference to (i) the change of temperature with time, (ii) the evolution of carbon dioxide with time and (iii) the change in density with time.
Chemistry
Carry out an investigation to study the pH changes that take place when neutralisation reactions occur between two named acids and a named base
