2nd Year Science Experiments:
The following pictures show students from 2A class investigating the force of FRICTION.
They used wooden blocks, Newton Spring Balances, sandpaper and oil. Aftertheir investigation students write up their results in their experiment copies. Over the 3 years of Junior Cycle S cience , students carry out 47 mandatory experiments.The write up of all of these experiments contributes to 10% of their Junior Cert science grade.
