Coursework B - Student Investigations

Each student is required to undertake two specified investigations in their third year and to submit a pro forma report on these for assessment. These additional investigations, based on the topics and learning outcomes in the syllabus, will be set by the examining body and will vary from year to year. These investigations account for 25% of the students final Junior Certificate grade and will require substantial time investment, by the student, during the year. Students will be notified of the investigation titles well in advance of the laboratory time they will be allocated to conduct the investigations, and this laboratory time-slot cannot be altered (In Loreto Balbriggan, this takes place typically after the Mock examinations - 2017 dates to be finalised yet).

DES deadlines for submission by the students of their report must be adhered to, and, in order to prevent missed deadlines, students are expected to demonstrate initiative and exercise due diligence in the preparation, planning and conduct of their chosen investigations. Students who fail to do so will not be given additional time, and reports still incomplete come deadline, will be submitted as is.

Each candidate is responsible for her own individual work and this work may be invalidated on the grounds that it cannot be verified as being the candidate's own individual work. See circular S68/08 below for more details.

 

Investigation Titles 2017

Biology

Investigate quantitatively, to determine the impact of each additive, the effects on samples of a garden soil of adding 20% by mass of (a) sand, (b) potting compost, and (c) clay* on

(i) the soil's ability to retain water,

(ii) the rate of drainage of water through the soil.

* Some readily available cat litter is composed of dry clay.

 

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 effect on its resistance.

Glossary for science investigations

Make sure you understand these words before you begin your investigation

Preparation and planning - Student guidelines

These guidelines give some pointers to students about how they should approach the investigations.

Investigation overview

This chart outlines investigation at each step along the way

Preparation and planning - Student worksheet

Use this for roughwork when researching/conducting the investigation - it is a sample pro forma booklet from the Department of Education. (basic version)

Sample Write up

Students might find this sample write up helpful, of an investigation from another year, as they prepare for their own investigations.

Suggested Marking Scheme

This page gives an idea of how marks are typically awarded. However, it should be noted that there may be slight variations from year to year, and from investigation to investigation. Students should consider this page in advance of preparing their investigations
