Key Stage 3

Key Stage 3 Chemistry

By its very nature everything around us is chemistry in motion and KS3 pupils begin their journey into chemistry by exploring the reactivity of elements and how they change to form new substances. The business of chemistry transforms the natural raw materials of the earth, sea and air into all of the products that we use in modern life and our KS3 chemists consider the principles of green chemistry that allow economic and environmental progress to proceed in harmony. This includes some important ideas on recycling and pollution. There are frequent practical lessons to investigate the wonder of chemistry first hand as well as a bank of interactive WebQuest activities which pupils can access in school and at home.

Practical work forms an integral part of the Chemistry course at BHS and all experiments, whether class practical or teacher demonstration, are carried out in accordance with the policies stated in the Department Health & Safety Policy herein. An analysis of the hazards associated with each practical and demonstration has been carried out in accordance with information supplied by CLEAPSS.

The Chemistry course for the first three years is delivered as part of the schools Junior Science scheme in accordance with the NI Revised Curriculum at Key Stage 3. All Chemistry staff teach some Junior Science classes. At the end of Year 10, many pupils choose to study GCSE Chemistry.

 

 

Year 8 Chemistry (3 periods per week)

The year begins with a study of safe practice and associated hazards in the laboratory which leads into investigations of the effect of heating substances. As the year progresses the concepts of Atoms, Elements and Compounds are explored. This topic includes a Cross Curricular Assessment Task on Using Mathematics. The final chemistry topic is about mixtures and includes some introductory work on separating techniques.  There are two examinations in this year. The first is at the start of the Spring term in January and the second is towards the end of the Summer Term. These examinations will begin the collection of information used in part to inform pupils on the choice of GCSE courses. There are tests at the end of each topic.

 

 

Year 9 Chemistry (3 periods per week)

 The initial topic will look at air as a mixture of gases which leads into the biology topic of breathing and respiration. The next chemistry section is called Metals and Reactivity Series and explores the reactivity series of metals through experiment and develops the Year 8 work on acids and bases. Pupils consider Chemical Reactions as a source of chemical resources in the final chemistry topic of the year. This topic includes some important ideas on recycling and pollution. There are two examinations in this year. The first is at the start of the Spring term in January and the second is towards the end of the Summer Term. These examinations will continue the collection of information used in part to inform pupils on the choice of GCSE courses. There are tests at the end of each topic as well as a bank of WebQuest activities which can be placed on VLE for pupil access in school and at home.

 

Year 10 Chemistry (3 periods per week)

 The year begins with a study of the ways in which chemists study the speed of chemical reactions. It is a measuring activity where pupils plan and carry out a rates experiment on marble chips with acid. The structure of the atom is introduced next followed by a topic concerning typical reactions of acids in the formation of salts.  Then the central position that the Periodic Table holds in chemistry and its usefulness in identifying patterns and trends is introduced. The year concludes with topics on Useful Reactions and a study of the chemistry important non-metals and gases. There are two examinations in this year. The first is at the start of the Spring term in January and the second is towards the end of the Summer Term. These examinations will continue the collection of information used in part to inform pupils on the choice of GCSE courses. There are tests at the end of each topic.
