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-
A project the children enjoy is making marshmallow molecules This activity will help your students understand the difference between an atom and a molecule Tell the children that each marshmallow represents an atom Toothpicks are used to join the atoms When atoms are joined they will form a molecule To begin, each child should receive

Atom 3-D Model Project
Build a 3-D Bohr model of an atom using materials of your choice. Your model must be a free-hanging, three-dimensional structure with protons, neutrons, electrons, and electron energy levels clearly visible. Hint: this drawing represents a Bohr diagram of a carbon 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: Summary: When you turn in your atom, it needs to be accompanied by a 75-word summary. Some of the questions that should be answered in your summary are atomic name, symbol, atomic number and atomic weight of your atom. How many electrons, protons and neutrons does your atom have? Where on the periodic table is your atom found (ex. metals, metalloids, non-metals, noble gases). What are the properties of your element? Where can you find it naturally? What products is it in?
Isotopes of your atom? Electron configuration.
Number of valence electrons. Any other relevant
information 30 points
Finished Product: The project demonstrates pride in workmanship. The 10 points Adapted from Physical Science Matter & Motion by Edwar Shevick 1998 individuality of the project is readily apparent. Energy Levels: Correct number of electron energy levels. 10 points Electrons: Correct location and number of electrons are represented. 10 points Protons: Correct number of individual protons are represented. 10 points Neutrons: Correct number of individual neutrons are represented. 10 points 80 Total Points
Other Requirements:
The 3D model needs to hang or stand by itself. Size should not exceed 18 inches wide or high. It is encouraged to use cheap, easy to find materials such as wire, Styrofoam balls, or beads; no perishable food, but candy is acceptable. The protons, neutrons, and electrons should be color coded, and a key should be included on the label.
