We describe four classical undergraduate physics experiments that were done with everyday objects and low-cost sensors: mechanical oscillations, transmittance of light through a slab of matter, beam deformation under load, and thermal relaxation due to heat loss. We used these experiments to train students for experimental homework projects but…

The application of the Reaction Monte Carlo (RxMC) algorithm to standard textbook problems in chemical reaction equilibria is discussed. The RxMC method is a molecular simulation algorithm for studying the equilibrium properties of reactive systems, and therefore provides the opportunity to develop computer-based "experiments" for the…

This paper describes investigative homework with apples, aiming to contribute to the primary-school students' understanding of density and conditions leading to floating and sinking. The assignment represents an opportunity for individual autonomous learning of physics and adoption of established scientific concepts through practical activities…

This article reports a set of two homework assignments that can be used in a second-year undergraduate organic chemistry class. These assignments were designed to help reinforce concepts of molecular geometry and to give students the opportunity to use a technological database and data mining to analyze experimentally determined chemical…

Discusses the use of two television sets with UHF coverage and a window screen or aluminum foil reflector to conduct a take-home experiment in physics. (CC)
