Larkhall Academy

National 4 Chemistry

Chemical Changes and Structure

In this Unit, learners will develop scientific skills and knowledge of the chemical reactions in our world. Through practical experience learners will investigate rates of reaction, energy changes of chemical reaction, and the reactions of acids and bases and their impact on the environment. Focusing on these reactions, learners will work towards the concept of chemical equations. Learners will research atomic structure and bonding related to properties of materials.

Nature’s Chemistry

In this Unit, learners will research the Earth’s rich supply of natural resources which are used by each and every one of us. Learners will investigate how fossil fuels are extracted and processed for use. They will investigate: the chemistry of using fuels, their effect on the environment and the impact that renewable energy sources can have on this; plants as a source of fuels, carbohydrates and consumer products; and how chemists use plants in the development of products associated with everyday life.

Chemistry in Society

In this Unit, learners will focus on the chemical reactions, properties and applications of metal and alloys. The chemistry of metals in chemical cells is explored. Through research, learners will compare and contrast the properties and applications of plastics and new materials. Learners will investigate the use of fertilisers, the formation of elements, and the presence of background radiation, and will research the use of chemical analysis for monitoring the environment.

Added Value Unit: Chemistry Assignment

In this Unit, learners will draw on and extend the skills they have learned from across the other Units, and demonstrate the breadth of knowledge and skills acquired, in unfamiliar contexts and/or integrated ways.

Skills, knowledge and understanding

♦ demonstrating knowledge and understanding by making statements, describing information, providing explanations

♦ applying knowledge of chemistry to familiar situations, interpreting information and solving problems

♦ planning experiments to illustrate a particular effect, applying safety measures

♦ carrying out experimental procedures, safely, recording general observations and collecting data

♦ using information handling skills by selecting, presenting and processing information

♦ making generalisations based on evidence/information

♦ drawing valid conclusions and giving explanations supported by evidence

♦ suggesting improvements to experiments

♦ communicating findings/information
