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
