healthy water balance
Material choices
- How we measure the
properties of a material
and why this is useful

gain from it
- Why the molecular
structure of materials is
useful
- Nanotechnology
Radiation and life
- What are the types of
electromagnetic radiation
- Which of these harm

- Where does salt come
from and why is it so
important
- Why we need alkalis
and chlorine
- How do we make these
resources
- How can we make our
use of these sustainable
and safe
Sustainable energy
- How much energy do
we use
- How can we generate
electricity
- What energy sources
should we use
Sources of revision:
 Exercise books
 Text book
 Tests and targeted areas from lessons
 Revision guides available from the Science department. £7 for the course. These
contain not only revision information but also exam questions.
 BBC bitesize: http://www.bbc.co.uk/education/subjects/zrkw2hv
 Class tasks.
 Home revision: individual and group.
 Tuesday revision sessions after-school in the Science pod.
 OCR website for past papers: http://www.ocr.org.uk/qualifications/gcse-twenty-firstcentury-science-suite-science-a-j241-from-2012/
 Doddle learn has a large amount of resources which the class teacher will assign but
there are also power points that the students can access.
Pupils need to focus chiefly on four areas:
 Subject knowledge and understanding of topics listed above – they may need to apply
their knowledge to new situations or circumstances.
 Key words and definitions – make a glossary of key words on flash cards to learn them
 Literacy - students need to answer longer response questions e.g. Quality of Written
Communication questions are worth 6 marks. The students need to plan this in the
same way as they would plan an English answer.
 Numeracy – students will need to be able to interpret data from tables and graphs as
well as drawing their own. They will also need to carry out some calculations in each
paper.
Equipment – in order to be fully prepared for their lessons and exams students will need:
 Stationery – pens (black ink), pencil, eraser, sharpener and ruler.
 Calculator.
All of the above are covered in lessons BUT they need to be reinforced independently by
pupils, ideally with your support.
Should you have any questions then please contact your child’s relevant teacher.
