Practical support to help you deliver this Edexcel specification
Scheme of work
This scheme of work has been produced to
help you implement this Edexcel specification. It is offered as an example of
one possible model that you should feel free to adapt to meet your needs and is
not intended to be in any way prescriptive. It is in editable Word format to
make adaptation as easy as possible. (Please note: the single science specifications
comprise two papers: Paper 1 assesses only content which is not in bold, and Paper 2 assesses all
content including content in bold.)
Other course planning support
You will find other support for planning
the course in the Teacher Support Materials. This is a free downloadable
resource that you can access at www.edexcel.com/igcse2009
Teaching resource exemplars
The scheme of work contains suggestions
for resources that you can use to support your teaching. These are suggestions
only of material you may find useful and you are encouraged to use a wide range
of resources that suit the needs of your students.
Other Edexcel teaching resources
·
Student Books – full colour textbooks matched to
the specification.
·
ActiveBook – a digital copy of the Student Book
in the back of every copy.
·
Double Award Student Guide – provides a complete guide to
using the Edexcel IGCSE Biology, Chemistry and Physics Student Books to teach
or study Science Double Award.
·

Edexcel Subject Advisors
Edexcel has a team of specialist subject
advisors available to help you with implementation of this specification. You
can contact them by email or phone.
Telephone: 0844 576 0037
Edexcel additional support
Ask the Expert – puts you in direct email
contact with over 200 of our senior subject experts.
Edexcel’s community forum – these message
boards are designed to enable you to access peer-to-peer support from fellow
Edexcel teaching and delivery staff in schools and colleges.
Health and safety
The
practicals and experiments suggested within the Scheme of Work are those which
we believe are not banned or restricted in any way and are still currently used
in most schools and colleges.
The
IGCSE encourages experimental work with the assessment of investigative skills
being made in the written examinations.
We
advise teachers and technicians to discuss the merits of the suggested
practicals when deciding which to carry out and how they will be carried out.
For example, will it be demonstrated by the teacher or technician, or conducted
by students themselves either individually or in small groups, under the
guidance and direction of the teacher.
You
may have ideas for practical work which we have not suggested but would work
equally well.
As in all practical work, a risk
assessment is expected as part of good health and safety practice in all
centres and we understand that many schools and colleges refer to the CLEAPSS
service: http://www.cleapss.org.uk/
for guidance and support in conducting science practical work.
Websites
There are links to relevant websites in this scheme
of work. In order to ensure that the links are up-to-date, that the links work,
and that the sites are not inadvertently linked to sites that could be
considered offensive, we also have made the links available on our website at www.pearsonhotlinks.co.uk. If you find
that a link from the scheme of work no longer works, please go to the
pearsonhotlinks site, where you can also report if a link needs fixing.

The number of guided
learning hours required for this Double Award qualification is 240–280 for all
three sciences (80–100 hours for each individual science). This equates to
approximately 1.5 hours per week over 60 weeks (for each science) and reflects
how centres will use time for practical activities differently. Guided Learning
Hours are all the times when a teacher is present to give guidance.

results of Geiger and Marsden’s experiments with gold foil and alpha
particles
7.16 describe
Rutherford’s nuclear model of the atom and how it accounts for the results of
Geiger and Marsden’s experiment and understand the factors (charge and speed)
which affect the deflection of alpha particles by a nucleus
|
Activities:
●
Complete examples on
Rutherford scattering, including past IGCSE questions.
Demonstration:
●
Watch applet showing
Rutherford scattering.

Students will be assessed on their ability to:
7.17 understand that
a nucleus of U-235 can be split (the process of fission) by collision with a
neutron, and that this process releases energy in the form of kinetic energy
of the fission products
7.18 recall that the fission of U-235 produces two daughter nuclei and a small number of neutrons
7.19 understand that
a chain reaction can be set up if the neutrons produced by one fission strike
other U-235 nuclei
7.20 understand the
role played by the control rods and moderator when the fission process is
used as an energy source to generate electricity
|
Activities:
●
Balance fission equations.
Demonstration:
●
Watch applet showing nuclear
fission.
