For all Junior Cert Students!!!!
We will start experiments on the week of the 18th Jan
Chemistry: Investigate quantitatively, at room temperature, the effect of dilution on the pH of (i) vinegar, (ii) a solution containing 5 g washing soda per litre of water, (iii) a solution containing 5 g sucrose per litre of water.
Physics: Using conductors made of children’s play (modelling) dough, investigate quantitatively the effect on resistance, calculated from measurements of voltage across and current through the conductors, of changing the conductor length and obtain data to establish whether dough colour has an effect on its resistance.
