Atomic Model Project - Eagle Mountain-Saginaw Independent
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
PowerPoint - Models of the Atom - A Historical Perspective
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:
PowerPoint - Models of the Atom - A Historical Perspective
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
The Atom for Middle School - Miss Little's Classroom Website
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
Computational Chemistry in the High School Classroom
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-

More than ____________thousand years ago, A Greek philosopher named____________ led a group of scientiVPV QRR NQRRQ MV ¶MPRPLVPV·B These early Greeks thought that the atom was the ____________ possible piece of matter that could be obtained. They guessed that the atom was a small, ____________particle, and that all the atoms were made of the same material. They also thought that different atoms were different shapes and sizes, that the atoms were infinite in number, always ____________ and capable of joining together. In 1803, ____________ proposed an atomic theory. The theory stated that all elements were made of atoms and that the atoms wereŁŁŁŁŁŁŁŁŁŁŁŁ MQG LQGHVPUXŃPLNOH SMUPLŃOHVB GMOPRQ·V POHRU\ MOVR VMLG POMP
atoms of the same element were the same, while atoms of different elements were ____________. The theory also said that____________ were made by joining the atoms of two or more elements together. In 1897, J.J. Thomson discovered a particle even smaller than the atom. He named it the ____________, but today we call it the ____________. As a result of his discovery, Thomson proposed a new atomic ____________.$ŃŃRUGLQJ PR 7ORPVRQ·V PRGHO POH MPRP RMV OLNH M SOXP ŁŁŁŁŁŁŁŁŁŁŁŁ LP
was mostly a thick, positively charged material, with negative electrons scattered about it like ____________ in a pudding. In 908, Ernest Rutherford took an extremely thin sheet of ____________ and bombarded it with electrons. Much to his surprise, most of the electrons went right through the foil, and the occasional ____________ was seriously deflected. To him, this seemed as likely as a baseball going through a brick wall. He theorized that the gold foil must be mostly empty ____________, or else the electrons would bounce off most of the time. He figured that the atom was made up of a small, dense, positively charged center, called the ____________. RutherIRUG·V POHRU\ OMV POH HOHŃPURQV V F D W W H U H G D U R X Q G W K H D W R P
