Junior Cycle Science explores how the natural world works, from the smallest particles to the vast universe. Students study key areas including biology, chemistry, physics, and Earth & space, while developing an understanding of scientific ideas, processes, and their impact on everyday life and society.
Students actively work like scientists by:
- Designing and carrying out experiments
- Analysing and interpreting data
- Solving problems and thinking critically
- Communicating scientific ideas clearly
- Working collaboratively in groups
They develop skills such as inquiry, reasoning, creativity, and decision-making, as well as scientific literacy—understanding and evaluating real-world scientific issues.
Assessment in Junior Cycle Science
Classroom-Based Assessments (CBAs) including the Extended Experimental Investigation (2nd Year) and Science in Society Investigation (3rd Year)
There is also an Assessment Task (linked to CBA, worth 10%) and a final written exam at the end of 3rd Year
There is a strong focus on ongoing assessment, feedback, and practical work, not just exams.
Differences Between Junior & Senior Cycle
Broad, integrated science course (biology, chemistry, physics combined)
Focus on skills, inquiry, and understanding
Continuous assessment alongside final exam
Subjects are studied separately (Biology, Chemistry, Physics)
More in-depth and specialised content
Greater emphasis on final exams and academic detail
Assesment of Leaving Certificate science subjects involves a final exam worth 60% and a 40% AAC (Additional Assessment Component) which is an extended practical investigation supporting research, design, practical and evaluation skills.
