An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

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...

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...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

This wonderful recap of powerful figures in scientific history includes pictures, important dates, and the information about their inventions or impact. Atomic structure and the photoelectric effect are introduced. The first slide gives...

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...

Atomic theory as a philosophical study was explored even by the Ancient Greeks. The knowledge of atoms was developed in the 17th century.  This PowerPoint explains how by the 1940's, splitting of the atom was discovered and since...

Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

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...

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

Brilliant graphics depict a variety of allotropes, especially the allotropes of carbon. Some notes are available to help make these useful for teaching your young chemists, but not for every slide. With some additional preparation on...

Good for setting the context for 20th century foreign policy issues, these slides describe key points in Latin America, the Middle East, the Far East, and Europe. US or World History classes will appreciate the concise list on each...

This guided lesson summarizes the historical development of atomic theory.

A slideshow looking at the contributions of scientists over time to our understanding of atomic theory. Looks at models of the atom developed by Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and James Chadwick, as...

A detailed slideshow for Grade 8 students that looks at the history of our understanding of atoms. Looks at the ideas presented by Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr, and the modern-day wave model. A...

Slideshow looking at the history of models of the atom, including those proposed by John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and James Chadwick. Discusses subatomic particles, including the numbers of protons, neutrons,...

This lesson reviews Dalton's Atomic Theory and explains each of the points.. It is 2 of 3 in the series titled "John Dalton."

Short slideshow looking at the history of models of the atom, including the contributions of Aristotle, Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr.

A guided lesson explaining Democritus' description of matter as discontinuous.

After an introduction, this site breaks down into sections discussion quantum theory, including A Quantum Theory for Energy, A Quantum Theory for Atomic Structures, Waves or Particles, Quantum Mechanics, and Interpreting the Quantum World.

This lesson explains Rutherford's gold foil experiment and the discovery of the nucleus. It is 2 of 3 in the series titled "Ernest Rutherford."
