Superconductivity was discovered one hundred years ago. After a short history of its discovery we discuss the basics of the underlying physics, how it can be explained in school, examples of how it is now used and what might be the future possibilities. […]
In the eighties the author developed an introductory science course for 15 year old students at the beginning of secondary school in Holland. The aim of the course was to show how scientific knowledge, leading to laws and theorization through models, […]
The article describes a simple experiment to illustrate the exponential decay of a water column. The liquid flows through a capillary tube obtained by removing the wire from a thin electric cable. […]
A technique is explained on how to insert tightly and pressure whithstanding a thin poliethilene tube in the closing stopper of a plastic bottle […]
Most introductory physics students spend the majority of their time in passive and often crowded lectures. Studies show that students learn little in such classes. The results of education research have led to the design of active learning environments (often making use of computer-assisted data acquisition tools). […]
