The JC science investigations for 2016 are out.

Investigate and compare the quantitative effects of changing
(a) the duration of light physical exercise and
(b) the time elapsed since the exercise stopped on the pulse rate of a person.

Investigate and compare the quantitative effects of changing
(a) the rhubarb surface area and
(b) 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).

Investigate and compare the quantitative effects of changing
(a) the pendulum length and
(b) the mass of the pendulum bob on the period (time of oscillation) of a simple pendulum oscillating through a small angle.

Looks like most students will be choosing the biology and physics investigations. The chemistry investigation, however, is easier that it initially seems. It is a type of colorimetric test that is used a lot by chemists. It has many applications and is a good opportunity for students to learn about the commonly used colorimetric test and the chemistry of oxalic acid - in particular, its poisonous effects on the human body.
The biology and physics investigations are definitely much easier to carry out and require a lot less equipment. However, when it comes to completing the coursework B booklet, there will be no difference between the three investigations when compiling, graphing and analysing the data.
Best of luck to all students!
There will be a review of the 2015 Leaving Cert Biology Marking Scheme this evening Thursday 15th October 2015 from 7.30 - 9pm in the new Education building beside The Bish
