Atomic Theory Jigsaw
Student Instructions
Students will be split into groups of six, with any remainders joining groups larger than six. These are your “Jigsaw Groups.” Within your groups, number off one through six. Next, groups will split up and each member will become an expert in one aspect of the topic. For this activity, each member will become an expert on one atomic model from history. After numbering off one through five, find all other students in the classroom who share that number. These will be your “Expert Groups.” In your Expert Group, research the assigned topic and answer the following questions:
Use the following questions and directives as guidelines to gather information. Do not limit information to just these questions. TAKE NOTES ON THIS MATERIAL
At the end of your allotted time, return to your base group and use your expertise to teacher the development of your model of the atom to your group members. In addition with your group (and as your HW), draw a timeline of the history of the development of the atom. EACH STUDENT WILL HAVE A TIMELINE FOR THEIR OWN NOTES. Be certain that your timeline includes what discovery or technology facilitated the development of each of the 6 models and why each of the models has changed.
TIMELINE REQUIREMENTS-DUE THURSDAY SEPT 24th
a. Timeline must be on the given paper.
b. Picture(s) of the person(s) – this is the only computer image allowed on the poster.
c. Date of the scientific contribution
d. Hand-drawn image of any equipment or apparatus used/invented
e. hand-drawn model of the atom, based on the scientist/philosopher’s theory
f. Description of the experiment – how it worked, and how the results contributed to the current theory of the atom.
g. What was the ultimate result of the experiment?

- What time period does your topic cover
- What special equipment did the scientists use to develop and support their model
- What was the major discovery that led to the development of this model.
- Draw an illustration of the model of that atom
