Atomic Model Project 1st six weeks PROJECT 5 – ATOMIC MODELS BACKGROUND: We have learned about atomic structure, what atoms are made of and how they look Now it is time to build a model of an atom ASSIGNMENT You will be assigned an element You will build a 3-D representation of one atom of that element, no “flat” models will be allowed
atom This is an individual project - each student will build their own atom model outside of class using scrap material available at home Materials must be non-perishable (if it is edible, DO NOT use it) and APPROPRIATE for classroom display Project Deadline: Monday, October 27, 2014 Scoring Rubric: Your project will be scored as follows:
HISTORY OF THE ATOM 1856 -1940 Joseph John Thompson In 1904, Thompson develops the idea that an atom was made up of electrons scattered unevenly within an elastic sphere surrounded by a soup of positive charge to balance the electron's charge It is called the plums pudding model He was awarded a Nobel Prize in 1906 for discovering the Electron
atom: the smallest particle of an element that has all the properties of that element The atom has nocharge The 3 main subatomic particles that make up the atom are the proton, neutron and electron nucleus: small, dense positively charged center of an atom protons and neutrons are found in the nucleus
As technology continues to improve, it is the hope of this project group that stu-dents can now benefit from such programs as well Research was done to determine con-tent areas high school chemistry students typically struggle with that fall under the State of Massachusetts chemistry educational standards A teaching module consisting of a se-

1st six weeks
PROJECT 5 ATOMIC MODELS
BACKGROUND:
We have learned about atomic structure, what atoms are made of and how they look. Now it is time to build a model of an atom.
ASSIGNMENT
You will be assigned an element. You will build a 3-D representation of one atom of that element, than paper (Styrofoam balls, wood, balloons, food, pipe cleaners). Separate colors must be used for each part of the atom. A color key must accompany your project. Also a 2 paragraph essay must accompany your project. Your essay should include a detailed description about the element that was assigned to you.
Your essay should include the following:
o The name of the element o How the electrons are arranged around the nucleus o Interesting properties that the element contains. o Who discovered the element o Where the element can be found o What the element is used for o DO NOT cut and paste information from websites! The atomic model must be scientifically accurate! * The model should have the proper number of protons, neutrons and electrons.
The atomic model must be properly labeled
ASSESSMENT
Your model will be graded on the following criteria: Y creativity, imagination and scientific accuracy.
Y Your model will be a major exam grade.
Y 25 points essay
Y 75 points model
DUE DATES:
Project is due on October 27th but can be turned in any day before that. Y
Y Use your imagination and creativity!
Y You DO NOT have to go out and buy anything! Use supplies around your house.

ACCURACY
TIMELINESS ESSAY
20: The
number of protons, neutrons and electrons are correct.
20: Well constructed,
demonstrates creative use of materials, and is a reasonable size.
20: The color key
is easy to read, clearly identified, and all parts are present and correct.
20: The student
completed and submitted the project on or before the required date.
20: The
student effectively discussed the element in detail and included all required information.
15: There is an
error in ONE of the atom particle totals.
15: Generally well
constructed, creative use of materials, and is reasonable size.
15: Key is easy to
read, clearly identified, with 1-2 errors in the required information.
15: The student
submits the assignment 1 day late.
15: The
student discussed the element and included all required information.
10: There is an
error in TWO of the atom particle totals.
10: Construction, OR
use of materials, OR size does not meet expectations.
10: Key generally
easy to read, clearly identified with 3-4 errors in the required information.
10: The student
submits the assignment 2 days late.
10: The
student discussed the element but did not include all the required information.
5: All three
atom particle totals are incorrect.
5: Overall failure to
meet expectations; haphazard material use and lack of effort is evident

difficult to read, is not clearly identified, or contains 5 or more information errors.
5: The student
submits the assignment 3 days (or more) late.
