Biology Project

Biology

Investigate and compare the quantitative effects of changing,

  • the duration of light physical exercise and
  • the time elapsed since the exercise stopped

on the pulse rate of a person.

Chemistry Project

Chemistry

Investigate and compare the quantitative effects of changing

  • the rhubarb surface area and
  • the temperature of solution

on the rate of reaction (measured by noting time for decolorisation of solution) between the oxalic acid in rhubarb and dilute potassium permanganate solution (acidified with sulfuric acid).

Physics Project

Physics

Investigate and compare the quantitative effects of changing

  • the pendulum length and
  • the mass of the pendulum bob

on the period (time of oscillation) of a simple pendulum oscillating through a small angle.
