Learners examine the history of equal temperament, the modern standard of tuning a piano. Proportion calculations of octaves and perfect fifths are utilized to calculate the frequency of each note in a major scale.

Learners gain a perspective in the development of chemistry. They understand some of the topics in their text and the ongoing nature of research. They then will be able to see the trends of the periodic table first hand through their own...

Students prepare an ad for an element, including properties and uses, in an attention getting format such as that used in the advertising business.

Young scholars intergrate science, technology and society into exploring the periodic table. They investigate one element of their choice and write a one page paper on the elements discovery, properties, uses, and the effect on society.

Students read an article that introduces them to the science and applications of nanotechnology. They discuss the the everyday examples of how nanotechnology is and can be used. In small groups, they observe and make inferences about...

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Pupils research animal characteristics including information about mammals, reptiles, birds, and fish. They place the information into a database and then, create playing cards using the information.

Students categorize items into one of the three states of matter. They participate in a demonstration in which they represent particles of matter. Finally, they complete an experiment in which they "race" top see who can make acetone...

Students relate to the idea of periodicity & give example of other periodic events and identify and use the periodic table as a useful resource. They also identify the relationship of elements to certain groups & periods &...

Lund University's on atomic physics. The site is quite comprehensive with information on projects, research, publications, reports, external sites, etc.

The FOM Institute for Atomic and Molecular Physics (AMOLF) is one of the five national research institutes of the Foundation for Fundamental Research on Matter (FOM). The research at AMOLF is focused on selected areas of atomic,...

This is a chart of the elements including the atomic mass, atomic number, symbol, half-life, and more.

[Free Registration/Login may be required to access all resource tools.] Students explain the workings of a mass spectrometer, and describe how this device is used to determine average atomic mass.

Students investigate the structure and parts of the atom, and learn about atomic mass and atomic number. They also explore the differences among solids, liquids, gases, and plasma.

This resource provides data about the physical destruction of Nagasaki, the medical aspect, and survivor stories.

Looking for more insight into particle physics? Search among several general particle physics resources. Or locate a specific particle physics institute in your area of the world.

What is a cyclotron and what does it have to do with atomic physics. Go to this site and find the answers to all your questions.

Several pages with an interesting discussion of the visible light spectrum and atomic absorption and emission line spectrum. Features excellent graphics, thorough and understandable discussion, and many interactive Java applets.

[Free Registration/Login Required] Uncover the relationship between pressure, force, and contact area in the context of a fire truck. Play with vehicle mass, number of tires, and guage pressure with this simulation to see what...

Several pages from an excellent site which describe the science of spectroscopy. The unique atomic emission (and absorption) line spectrum of elements are illustrated and explained. Includes a Java applet depicting the quantum energy...

At this site from The Nobel Foundation, read about the life and scientific discoveries of physicist Enrico Fermi (1901-1954), whose work with radiation and "discovery of nuclear reactions brought about by slow neutrons" earned him the...

An online course designed for the adult learner. "The 11 units, accompanied by videos, interactive simulations, and a comprehensive Facilitator's Guide, work together to present an overview of key areas of rapidly-advancing knowledge in...

From the Physics 2000 site, this page exemplifies their usual superb discussion of the concepts of heat, temperature, and absolute zero. Using an entertaining series of cartoon characters, the page gives a very understandable discussion...

[Free Registration/Login may be required to access all resource tools.] Rutherford's model of the atom was better than earlier models. But it wasn't the last word. Danish physicist Niels Bohr created a more accurate and useful model....
