An Estimation of the Number and Size of Atoms in a Printed Period
Peer reviewed Peer reviewed
Direct linkDirect link
Schaefer, Beth; Collett, Edward; Tabor-Morris, Anne; Croman, Joseph – Physics Teacher, 2011
Elementary school students learn that atoms are very, very small. Students are also taught that atoms (and molecules) are the fundamental constituents of the material world. Numerical values of their size are often given, but, nevertheless, it is difficult to imagine their size relative to one's everyday surroundings. In order for students to…

An Estimate of Avogadro's Number.
Peer reviewed Peer reviewed
Stauffer, Frederic R. – Physics Teacher, 1991
Calculates an approximation to Avagadro's number for one mole of water by assuming the mole to be in cubical form and then halving the cube three times, thereby doubling the surface area of the original cube. The calculations are derived from the work necessary to perform these divisions. Presents calculated values for several liquids. (MDH)

Investigating the Compton Effect with a Spreadsheet.
Peer reviewed Peer reviewed
Kinderman, Jesusa Valdez – Physics Teacher, 1992
Describes a computer simulation of the Compton effect designed to lead students to discover (1) the relationship of the electron's final kinetic energy to its angle of scattering and (2) the relationship between the scattering angles of the outgoing electron and photon. (MDH)
