Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

Young scientists learn how to select a scale factor for a large scale model. Then they figure the scale for each of the planets and the distance between them. Finally, they construct a giant scale model of the solar system and answer...

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...

How do we know so much about the atom? Explore the evolution of the atomic model through a video from an informative chemistry lessons playlist. The narrator describes how our view of atoms and subatomic particles has changed from...

Examine the experiment that led to the present-day atomic model. The video experiment shows the stream of electrons that travel through a vacuum between an anode and cathode. J.J. Thompson's model of an atom provides the explanation for...

Atoms may make up everything, but what are they made of? The narrator asks patrons at a local park what atoms are in an interview-style video. He then creates an atomic model and adds a neutron to it, opening the discussion to isotopes.

Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains multiple...

Students research the element of carbon, its composition, and the importance of carbon to life on earth. Then they design model mobiles of carbon atoms to demonstrate their understanding of the configuration of protons, neutrons, and...
