Chemistry

Acid-base and redox titrations to determine unknown concentration or molar mass.

Identifying cations and anions using reagents such as sodium hydroxide and aqueous ammonia.

Using bromine water and acidified potassium manganate(VII) to distinguish saturated from unsaturated hydrocarbons.

Measuring enthalpy changes (heat of solution) and tracking reaction rate via the "disappearing cross" method (sodium thiosulphate and acid).

Wiring circuits with cells, voltmeters and ammeters to determine EMF and internal resistance.

Using an illuminated object, convex lens and screen to determine focal length.

Timing oscillations to calculate acceleration due to gravity.

Investigating spring extension under varying slotted masses.

Using Benedict's, Iodine and Biuret reagents to test for reducing sugars, starch and proteins.

Investigating how temperature and pH affect enzyme reaction rate, e.g. amylase breaking down starch.

Observing weight/volume changes in potato cylinders or Visking tubing across sucrose concentration gradients.

Examining structural adaptations of leaves and flowers to identify them using a key.
