JUNIOR SCIENCE COURSE WORK B 2014
Students as you are aware you are about to carry out 2 Investigations worth 25% of your Junior Cert Science marks.
Careful preparation is essential to achieve high marks.
Investigation Titles 2014
Biology
Investigation and compare the effects of pH on the catalytic effect of the enzyme catalase, found in (a) celery and (b) animal liver, on the rate
of breakdown of hydrogen peroxide.
Chemistry
Investigation 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.
Below are some documents to help you with your project.
