BACKGROUND
TO HELP YOU PIECE TOGETHER THE STORY OF WHAT WE KNOW ABOUT THE “ATOM”, YOU WILL CREATE A TIMELINE DEPICTING THE
DEVELOPMENT OF THE SCIENTIFIC MODEL OF THE ATOM. IT HAS BEEN THROUGH NEW DISCOVERIES BY PHILOSOPHERS, SCIENTISTS AND
MATHEMATICIANS THAT THE MODEL OF THE ATOM HAS EXPANDED AND CHANGED OVER TIME. YOUR ASSIGNMENT IS TO RESEARCH THE MAJOR
CONTRIBUTORS AND SIGNIFICANT DISCOVERIES THAT HAVE IMPACTED THE ATOMIC MODEL AND DEVELOP A TIMELINE.
REQUIREMENTS
YOUR TIMELINE MUST…
 INCLUDE A PICTURE OF THE SCIENTIST
 BE CHRONOLOGICAL IN ITS SEQUENCE, WITH THE DATES CLEARLY SHOWN AND A MINIMUM OF 1 KEY CONTRIBUTION
(BULLET POINTS) TO THE MODEL OF THE ATOM FOR EACH SCIENTIST
 INCLUDE THE FOLLOWING PICTORIAL MODELS OF THE ATOM FOR EACH SCIENTIST/PHILOSOPHER, CLEARLY LABELING KEY
CHARACTERISTICS OF THESE MODELS (PROTONS, NEUTRONS, ELECTRONS, NUCLEUS, ETC…):
THE ORIGIN OF ATOMIC THEORY (ATOMA)
SOLID SPHERE MODEL (BILLIARD BALL)
MODERN MODEL
PLANETARY MODEL
PLUM PUDDING MODEL
NUCLEAR MODEL
QUANTUM MECHANICAL MODEL
 DISPLAY THROUGH PICTURES AND/OR DIAGRAMS THE SIGNIFICANT CONTRIBUTIONS AND EXPERIMENTS OF THOSE SCIENTISTS
AND ATOMIC MODELS EXAMINED IN THIS PROJECT. FOR EXAMPLE, WHERE AN EXPERIMENT OR MODEL IS LISTED AS A
CONTRIBUTION, A PICTURE/MODEL WITH LABELS WOULD BE APPROPRIATE. A MINIMUM OF 1 PICTURE/DIAGRAM (OF THEIR
CONTRIBUTION/EXPERIMENT) PER SCIENTIST IS REQUIRED.
 YOU MUST CREATE A DIGITAL TIMELINE USING POWERPOINT, PREZI (www.prezi.com), TIKI-TOKI (www.tiki-toki.com),
DIPITY (www.dipity.com), etc. YOU MUST EMAIL ME YOUR TIMELINE, or THE LINK TO YOUR DIGITAL TIMELINE
(SNOWT@HUDSON.EDU) BY THE DUE DATE.
GUIDELINES
 USE YOUR TEXTBOOK AND THE INTERNET AS RESOURCES
 YOU DO NOT HAVE TO FOLLOW THE TYPICAL HORIZONTAL TIMELINE FORMAT; YOU MAY BE CREATIVE AND USE ANY FORMAT YOU WISH
AS LONG AS IT IS LOGICAL.
