Nuclear Reactions - Rutherford's Alpha Scattering Experiment
Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...
Curated OER
Atomic Structure
The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...
Curated OER
Modern Physics, Old QT
In this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.
Curated OER
Atoms, Molecules and Ions
Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

Defining the Atom
Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...
Mr. E. Science
Atoms and Bonding
I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms in an equation,...

Physicists or Philosophers?
Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...
Curated OER
Inside an Atom
In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.
Curated OER
Periodic Table Basics Review Sheet
For this periodic table worksheet, students complete a chart with the appropriate element symbol, the atomic mass and the atomic number. They classify elements by their groups and as metals, nonmetals or semi-metals. They also answer two...
