Combined Science - CCEA Single Award

What can we learn about cells and their structure from examining them in very fine detail?

Food provides energy and nutrients. Why do the different components of our diet have various sources and functions?

Green plants absorb light in their leaves and convert it to energy by photosynthesis.

A communicable disease (usually caused by a microorganism such as bacteria, virus or fungus) can be passed from one organism to another.

Learn about how many chemicals are acidic, neutral or alkaline and how we can distinguish one from another using indicators.

Learn about the three main ways atoms and ions bond with each other (ionic, covalent and metallic) and how these types of bonding can be shown using dot and cross diagrams.

Learn how materials can have many different physical properties which make them suitable for a range of purposes.

Learn how symbols, formulae and equations help chemists explain chemical reactions in detail.

Learn about a range of chemical tests that can be carried out to identify a substance.

Learn how to measure rates of reaction and how to impact the rate by changing the temperature and concentration or by using a catalyst.

Learn how an organic chemical contains the element carbon and how there are many different homologous series of organic compounds such as alkanes and alkenes.

Plan, observe and evaluate experiments with a hypothesis, variables and conclusions, using scientific equipment like a measuring cylinder or a burette.

Scientific investigations have several stages - planning, collecting data, analysing data and evaluation. It is important to understand how to carry out each stage of the investigation.
