National 4 Chemistry Assignment 2

The Chemistry Added Value Unit assessment is an assignment. While describing what candidates must do, the published assessment offers considerable flexibility in the choice of a context for the assessment.

In the assessment, candidates apply skills, knowledge and understanding to investigate a topical issue in chemistry and its impact on the environment and/or society. The issue should draw on one or more of the key areas of the Course, and should be chosen with guidance from the assessor.

Centres can access the assessment through their SQA Co-ordinator.

Information on suggested topical issues can be found in the National 4 Chemistry Course and Unit Support Notes. It is not mandatory to use any of the topical issues suggested. A resource pack for one possible context for this assignment is also included in the National 4 Chemistry Course and Unit Support Notes.

As with all SQA Unit assessments, Added Value Unit assessments must be internally verified by centres.

These documents contain details of Unit assessment task(s), show approaches to gathering evidence and how the evidence can be judged against the Outcomes and Assessment Standards. Teachers/lecturers can arrange access to these confidential documents through their SQA Co-ordinator.

We are publishing examples of candidate evidence with commentaries as part of our Understanding Standards programme. These materials are for teachers and lecturers to help them develop their understanding of the standards required for assessment. As these materials become available, they are being published in the following locations:

  • Available from our secure website Materials relating to Unit assessment, internally assessed components of Course assessment, and externally assessed components of Course assessment which are subject to visiting assessment. Teachers and lecturers can arrange access to these materials through their SQA Co-ordinator.
  • Available from our Understanding Standards website Materials relating to externally assessed components of Course assessment, with the exception of those subject to visiting assessment.

More information on our Understanding Standards programme, can be found on our Understanding Standards page.

There was no verification activity at this level in 2017.

Pupils complete a series of three units of work - based upon the National 4 and 5 Chemistry Outcomes.

To assist with revision and consolidation, copeis of the current teaching materials are available below for consultation at home. Copies of the summary and homework booklets are also shown below for download / printing should you have lost your own copy.

All pupils have been issued with a Data Booklet. If a pupil should lose their copy, they should download and print one from the following link.

Unit 1: Chemical Changes and Structure

Unit 2: Nature's Chemistry

Unit 3: Chemistry In Society

Assessment Strategy

Before they may be presented at a National level, each pupil must sit and pass a written assessment for each key area of the syllabus. Each pupil must gain 50% or more of the available marks from the key area to be deemed to have passed that key area.

Assessments at National 3, National 4 and National 5 levels are available.

For National 5 Chemistry, in addition to the written assessments throughout the course and the end of year examination, pupils are required to complete and submitt a written assessed assignment. The assignment will follow an initial practical investigation with pupils then expected to go on and research the social, economic and environmental issues surrounding it. Pupils then, whilst under exam conditions, write up their report of between 500 and 800 words excluding charts and diagrams. It is anticipated pupils will be given an opportunity in Unit 1 to complete this area of assessment.

Pupils are reminded that their jotters form an important part of their assessment throughout S4 Chemistry, it is vital that work is completed legibly and to the highest possible standard during each and every lesson.

Attached are copies of revision worksheets, produced by the department to improve basic skills in Chemistry. Answers are available from your teacher.
