Project Year 8
Life, Death and Germs (Biological Science)
One of the major challenges facing the human
species is the threat of a global disease outbreak,
such as the most recent Ebola epidemic in Africa.
Microorganisms are becoming increasingly resistant
to the medical treatments we have available. If
humankind is to survive in the long term, we must
come to terms with our relationship with our
microscopic neighbours.
During this action project, students will complete a
substantial investigation by researching a disease that
has had or may have a major effect on the human
species, including how Science has contributed
to protecting people from diseases. Students will
develop research skills by researching a particular
disease, construct a three-dimensional cell model and
produce an information pamphlet.

Project Year 8
Crazy Cool Crystals (Earth and Space Science)
Three hundred metres below the the town of
Chihuahua Mexico is the Naica Cave which has
contains some of the largest natural crystals ever
found. Some measure 12 metres in length and weigh
over 55 tonnes. What conditions are necessary
for optimal crystal growth? In this Action Project
students will initially research crystal formations in
extrusive and intrusive igneous rocks.
Based on their research, students will investigate
factors that affect crystal growth with the aim of
growing the largest crystals. Students will be tasked
with choosing an appropriate solute, mixing supersaturated
solutions and modifying environmental
factors to grow the largest crystals in competition
with their peers.
