The Atomic Congress The evolution of atomic models

This game explores the meeting of five famous scientists from the past. During the meeting, the panel members will be asked to present, in chronological order, their model of the atomic structure and how it relates to others.

Students should be told to register for the game a week in advance, so that they can prepare a presentation for their character.

Students should review the power point presentation on evaluating reliable sources (in the game's resources).

Students should bring headphones so that they can watch the videos.

Get to know the characters


Democritus (Greek meaning "chosen of the people"), (c. 460 – c. 370 BC) was an influential Ancient Greek pre-Socratic philosopher primarily remembered today for his formulation of an atomic theory of the universe.

His exact contributions are difficult to disentangle from those of his mentor Leucippus, as they are often mentioned together in texts. Their speculation on atoms, taken from Leucippus, bears a passing and partial resemblance to the nineteenth-century understanding of atomic structure that has led some to regard Democritus as more of a scientist than other Greek philosophers; however, their ideas rested on very different bases. Largely ignored in ancient Athens, Democritus was nevertheless well known to his fellow northern-born philosopher Aristotle. Plato is said to have disliked him so much that he wished all his books burned. Many consider Democritus to be the "father of modern science".

John Dalton

John Dalton (6 September 1766 – 27 July 1844) was an English chemist, physicist, and meteorologist. He is best known for his pioneering work in the development of modern atomic theory; and his research into colour blindness, sometimes referred to as Daltonism, in his honour.

J.J Thompson

Sir Joseph John "J. J." Thomson (18 December 1856 – 30 August 1940) was an English physicist. He was elected as a fellow of the Royal Society of London and appointed to the Cavendish Professorship of Experimental Physics at the Cambridge University's Cavendish Laboratory in 1884.

Ernest Rutherford

Ernest Rutherford, 1st Baron Rutherford of Nelson (30 August 1871 – 19 October 1937) was a New Zealand-born British physicist who became known as the father of nuclear physics. 

Niels Bohr

Niels Henrik David Bohr (Danish: [nels ˈb̥oɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.[1]
