This website from Kathleen Cummings Dominguez at the Illinois Institute of Technology provides a lesson plan on the concepts of friction. It describes a lesson plan which will engage students in active classroom...

Created by David P. Stern this is the first of three linked web pages. The one listed introduces the concept of mass and the question of how it may be measured without recourse to gravity, e.g. in the weightless...

This two-part activity provides an introduction to the basics of measurement (linear, mass, volume, density) and discusses the role of inferential statistics in comparing any two measurements. The concept of random...

Created by David P. Stern this site consists of algebra-based material at the high-school level, oriented towards astronomy and spaceflight, which explores Newton's Laws and their application. Concepts are stressed such...

This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic...
