This publication presents a science activity and instructional information on the mechanics of granular materials, interparticle friction and geometric interlocking between particles which is a fundamental concept in many fields like in the study of earthquakes. This document describes the Mechanics of Granular Materials (MGM) experiments which…

Presents an application of the formulas of kinematics to the real driving situation, involving motion at constant speed and deceleration. Suggests the problem be used as an example in class, a homework assignment, or a test item. (CC)

Results of two multiple choice tests on mechanics administered to eighth grade students are discussed and reported by their respective teachers. (JH)

Discusses how difficult the various problems of pressure, partial pressure, gas laws, and vapor pressure are for students. Outlines the evolution of the concept of pressure, the gas equation for a perfect gas, partial pressures, saturated vapor pressure, Avogadro's hypothesis, Raoult's law, and the vapor pressure of ideal solutions.

Recent models of stellar nucleosynthesis can be effectively used to provide a unifying theme for the teaching of nuclear phenomena to chemistry students. (Author/DF)

Describes how four independent puzzles in nuclear physics converge in a single, unifying explanation--some nuclei can exist in two different shapes." (Author/TS)

The approach generally used in writing undergraduate textbooks on Atomic and Nuclear Physics presents this branch as historical in nature. Describes the concepts of astrophysics, plasma physics and spectroscopy as contemporary and intriguing for modern scientists. (PS)

Capillary and gravity water waves are related to the position, wavelength, and velocity of an object in flowing water. Water patterns are presented for ships and the whirling beetle with an explanation of how the design affects the objects velocity and the observed water wavelengths. (DS)
