In St. Mac Dara’s all students take science to 3rd Year. Junior Certificate Science is made up of the following components:

  1. Course work A- worth 10% of final mark.
  2. Course work B- worth 25% of final mark.
  3. Written exam- worth 65% of final mark.

During the course of the 3rd year, students are required to undertake two out of three investigations set by the Department of Education and Science (DES). The title of the investigations vary each year. These titles will be given to the students well in advance of the laboratory time they will be allocated in order to carry out the investigation so as to allow for individual background research and reading into the area.   These time allocations cannot be altered and no additional time will be given beyond the DES set deadline. In order to meet this deadline, students will be expected to exercise care in planning, preparing, organising and carrying their investigations. Students who fail to have reports completed by this time will have to submit report as they are ie, incomplete.

It is the responsibility of each candidate in the group to ensure that his/her work is clearly presented. Direct copying of material from secondary sources – other than essential references, e.g. definitions – is not permitted. All secondary sources used (books, journals, websites etc.) must be duly acknowledged.

Senior Chemistry

The subject has 80 practical activities, which are examined in the Leaving Certificate exam paper. Safety and laboratory skills are emphasised.

Senior Biology

Students follow a syllabus which covers a great variety of topics including food, ecology, enzymes, photosynthesis, respiration, genetics, evolution, microbiology, and plant structure and function. We all study human biology including reference to health and medical issues. The course has a large practical aspect to it and the students do many experiments, including an off-site ecology field trip.
