WG6 – Sixth Form Induction Information and Tasks
SUBJECT
Chemistry
In this subject you will be expected to:
Have an interest in chemistry; appreciate how society makes decisions about scientific issues
and how it contributes to the success of the economy and society. Have an enquiring mind and
be committed to study, meeting deadlines and have good problem solving skills.
You will need to have an interest in:
How chemistry works in the world around us, and questions why is this happening. Excellent
knowledge of Science and Mathematics.
Independent learning in this subject requires: ( include 5hrs of independent study)
Material that reinforces classroom knowledge, practical write ups, occasional pre-learning. Read
newspapers, Chem Guide, Chemistry world, New scientist and other publications. Appropriate
use of internet for further research.

Task 2: Research
Research and produce a scientific report for The New Scientist based on ‘Looking
for Patterns in Chemistry’.
The theories and ideas involved in the development of an atom’s structure would
give a fascinating insight into how science works. The scientific method is often
represented as the sequence of experiments, observation, analysis and
conclusion. The model of the nuclear atom – consisting of protons, neutrons and
electrons – is extremely useful and well accepted by the chemists and is firmly
based on sound experimental evidence. It is amazing to think that these
experiments all began with investigating particles that cannot ever be seen.
However, Science does advance. The nuclear model of the atom has now been
replaced and present models will also be replaced as Science advances further.
We have come a long way from the four elements of the ancient Greeks.
1. Describe how the model of the atom has changed over the years and how it
continues to do so?
2. How is scientific knowledge evolving?
3. Describe how new theories are accepted by the scientists?
Things to include:
Greek philosophers and the first idea of atoms and elements
a) John Dalton
b) Joseph John Thomson
c) Ernest Rutherford
d) Niels Bohr
e) Louis DeBroglie
f) Erwin Schrödinger
g) James Chadwhich
h) Hans Geiger
i) Ernest Marsden
