An astronomy "experiment" composed of three parts is described in the article. Being given necessary data a simple model of inner planets of the solar system is made in the first part with planets' circular orbits using appropriate scale. In the second part revolution of the figurines used as model representations of the planets along…

Experiments are described on collisions between two billiard balls and between a bat and a ball. The experiments are designed to extend a student's understanding of collision events and could be used either as a classroom demonstration or for a student project.

Research globally has shown that many children lose interest in science towards the end of primary school and throughout the post-primary phase. This article explores children's experience and views in Irish schools that have adopted innovative practices that aim to empower, excite and inspire children in science. One of these focuses on explicit…

The measurement of the force acting between two parallel, current-carrying wires is known as Ampère's experiment. A mechanical balance was historically employed to measure that force. We report a simple experiment based on an electronic precision balance that is useful in clearly showing students the existence of this interaction and how to…

Many students probably know something about space from playing computer games or watching movies and TV shows. Teachers can expose them to the real thing by launching their experiments into near space on a weather balloon. This article describes how to use high-altitude ballooning (HAB) as a culminating project to a chemistry unit on experimental…
