Practical Endorsement

The new Chemistry specification has changed (for the better) the way in which practical work is conducted at A Level. Through a minimum of twelve practical investigations (in practice there are more), students accumulate the scientific skills and laboratory techniques that will result in a smooth transition to degree‑level study. We have dedicated 2‑hour slots timetabled for practical work and these enable a proper learning experience for students. There is no graded assessment, although the end-of-course examinations will test students’ understanding of the experimental techniques they have employed.

Course outline:

The two-year A Level is made up of six units which are assessed in three written papers taken at the end of the second year. These papers test both the students’ theoretical knowledge and their understanding of, and application of, the practical chemistry skills that they have accumulated over the two years. The Practical Endorsement is a skills-based certification that runs the length of the course and which prepares students for successful progress in practical sciences at degree level.

Students have 10 lessons over a fortnight covering the content of the OCR course. Teaching is provided two Chemistry teachers, one Organic Chemistry specialist, the other a specialist in Inorganic/Physical Chemistry.

			Content Overview
A level (2 year)	Year 1	Autumn	Module 1 – Development of practical skills in chemistry	• Atoms and compounds • Electrons, bonding and structure • The periodic table and periodicity	• Molecules and equations • Amount of substance • Acid–base and redox reactions • Organic chemistry basic concepts
		Spring		• Group 2 and the halogens • Qualitative analysis • Enthalpy changes	• Hydrocarbons • Alcohols and haloalkanes • Organic synthesis
		Summer		• Reaction rates and equilibrium (Year 12 and 13 content)	• Analytical techniques (IR and MS)
	Year 2	Autumn		• Acids, pH and buffers • Enthalpy, entropy and free energy	• Aromatic compounds • Carbonyl compounds • Carboxylic acids and esters
	Year 2	Spring		• Redox and electrode potentials • Transition elements	• Nitrogen compounds • Polymers • Organic synthesis

Skills required:

Students should show strong deductive reasoning and problem solving skills, supported by solid numeracy. They should be able to assimilate new concepts and principles and apply them to novel situations; Chemistry is not a subject for those that learn by rote. They need to be well-organised both in the laboratory and in their studies outside of class. This should be reflected in their clear written communication of ideas and concepts. They need to be cooperative and demonstrate good interpersonal skills to enable efficient and precise practical work.
