GOLD
Compare and evaluate the health benefits of cooking
crisps in hard fat or vegetable oil
SILVER
Explain why vegetable oils are considered to be
healthier
BRONZE
Describe what is meant by saturated and unsaturated
fats and give an example of each
GOLD
Analyse how sedimentary rocks and the fossil record
can provide evidence for the age and history of the
Earth

Explain Wegener’s theory of continental drift, detailing
some of the evidence which supports his theory
BRONZE
Research and make a poster describing Hutton’s and
Wegener’s theories about how the Earth has formed
GOLD
Design a revision resource covering all aspects of the
C1 and annotate with balanced symbol equations and
key vocabulary where necessary
SILVER
Produce a spider diagram for chemistry and annotate
with explanations of key ideas

Review and make a key word list for the C1 topic from
the revision sheets provided
GOLD
Using the sheet of common ions provided, write the ionic
formula for potassium iodide, copper sulphate, magnesium
oxide and lithium nitrate
SILVER
Explain how sodium and chlorine form positively and
negatively-charged ions and why the ionic formula of
sodium chloride is NaCl

GOLD
Compare the bonding in diamond and graphite with
silicon dioxide, showing similarities and differences
SILVER
Explain why graphite unexpectedly conducts heat and
electricity
BRONZE
Describe the bonding in diamond, with a diagram,
explaining why this makes it the hardest natural
substance
GOLD
Compare the electrical conductivity of ionic, covalent
and metallic substances. Under what conditions will
ionic substances conduct electricity. Explain
