Atomic Theory Presentations
We are going to trace the history of atomic theory.
How did scientists discover the properties of the atom when it is so small that it can’t be seen? How did they design experiments to determine what atoms looked like or how they behaved?
What did the results of these experiments tell the scientists?
Where did some scientists go wrong?
How did scientists build on older theories to create newer, more correct theories?
What are the theories that scientists believe today?
Presentations will start on December 6th and finish on December 7th.
They will include:
1. a poster
2. a 4 to 6 minute talk per person
3. a written report to be handed in to me (about 1 page long) on the day of the presentation.
Some of the theories get very complex but you don’t need to go into all of the math & physics. Try to keep it interesting.
Presentations will be given in groups, but each person must contribute equally to the talk.
Each person must make a poster and hand in a written report.
Group 1: The Early Days (2 people)
John Herschel & William Wollaston & line spectra of gases. Jay
What is line spectra?
What is spectrum analysis
Group 2: Dalton Atomic Theory (2 people)
John Dalton – Law of Multiple Proportions & other theories Ryan & George
What other theories did Dalton have?
What was Dalton’s model? The billiard ball model
What were some of the problems with Dalton’s model?
Group 3: Experimental Evidence (2 people)
Michael Faraday – paramagnetism Maria & Clover
William Crookes – cathode ray
Group 4: the periodic table (2 people)
