Modelling the Atom: Create a timeline
In groups of 4-5 you will need to create a timeline of the model of the atom.
For each model you will need an A4 page profile of the model including:





Who developed the model
When was it developed
A diagram of the model
Explanation of its key features
How the scientists came up with the model
These will be arranged into a timeline of our understanding of the atom.
The five profiles that need to be made are:





John Dalton (Solid sphere or billiard ball model)
J.J. Thomson (Plum pudding model)
Ernest Rutherford (Nuclear model)
Niels Bohr (Planetary model)
Erwin Schrodinger (Electron cloud model)
Example:
Democritus
442BC
Democritus was an ancient
Greek Philosopher
His model of the atom was
that matter was made of
invisible particles called
atoms.
These atoms were solid and
had a uniform structure.
His model was based on
reasoning rather than
science.
