OCR GCSE 21st Century Additional Science
This course is taken after Science A (core science). There are three written papers, each one on a different science.
B4 – The processes of Life
~ How do chemical reactions take place in living things?
~ How do plants make food?
~ How do living organisms obtain energy?
C4 – Chemical patters
~ What are the patterns in the properties of elements?
~ How do chemists explain the patterns in the properties of elements?
~ How do chemists explain the properties of compounds of Group 1 and Group 7 elements?
P4 – Explaining motion
~ How can we describe motion?
~ What are forces?
~ What is the connection between forces and motion?
B5 – Growth and development
~ How do organisms develop?
~ How does an organism produce new cells?
~ How do genes control growth and development within the cell?
C5 – Chemicals of the natural environment
~ What types of chemicals make up the atmosphere?
~ What reactions happen in the hydrosphere?
~ What types of chemicals make up the Earth’s Lithosphere?
~ How can we extract useful metals from minerals?
P5 – Electric circuits
~ Electric current – a flow of what?
~ What determines the size of the current in an electric circuit and the energy it transfers?
~ How do parallel and series circuits work?
~ How is mains electricity produced? How are voltages and currents induced?
~ How do electric motors work?
B6 – Brain and mind
~ How do animals respond to changes in their environment?
~ How is information passed through the nervous system?
~ can reflex responses be learned?
~ How do humans develop more complex behaviours?
C6 – Chemical systems
~ Chemicals and why we need them
~ Planning, carrying out and controlling a chemical synthesis
P6 – Radioactive materials
~ Why are some materials radioactive?
~ How can radioactive materials be used and handled safely, including wastes?
