Key Stage 3 Chemistry
Chemistry is “the study of of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy”. Chemistry is one of the physical sciences that help us to describe and explain our world. Chemistry is involved in everything we do, from growing and cooking food to cleaning our homes and bodies to launching a space shuttle. Chemistry is taught as a separate subject and is divided into topics with students encouraged to make links between their learning in different topics.

How is This Subject Assessed?

The students take a test at the end of each topic. These are designed not only to enable students to be given a forecast grade but most importantly to identify any areas that students need to revisit. In addition to these tests, students will also plan and carry out investigations. Students will be assessed on their ability to design investigations, to set up and use apparatus, and to collect, record and analyse their results. They will also be expected to evaluate the quality of the data they have collected and their experimental methods.  Assessment will be a mixture of self, peer and teacher assessment.
