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...

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...

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 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...

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...

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...

"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....

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,...

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...

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 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...
