Composting can provide both a means of managing organic waste, and a vehicle to teach Science at all levels of schooling. In response to a local organic waste issue a process has been developed to compost waste from an olive oil press and analyse the resultant compost. In this article, the composting process is described in a manner that can be…

Newton's experiments into the resistance which fluids offer to moving bodies provide some insight into the way he related theory and experiment. His theory demonstrates a way of thought typical of 17th century physics and his experiments are simple enough to be replicated by present day students. Newton's investigations using pendulums were…

The ubiquitous change jar (or any other container) is the focus of this investigation. Using random pocket change, a distribution is determined and statistical tools are employed to calculate the value of given volumes of coins. This brief investigation begins by considering money, which piques the interest of most students, and uses this…

Detection of biologically active compounds is one of the most important topics in molecular biology and biochemistry. One of the most promising detection methods is based on the application of surface plasmon resonance for label-free detection of biologically active compounds. This method allows one to monitor binding events in real time without…

High-ability students in grades 3-8 received lessons in organizing a creative investigation and were then compared to control students not receiving the lessons. The most important variables predicting whether the student initiated a creative investigation were membership in the experimental group and pretreatment self-efficacy scores for creative…

Describes the process of problem identification, data collection, and generalization in a mathematical experiment to find the speed at which a bug travels at the end of a fan blade. Presents the learning outcomes of the experiment and possible implications of using this teaching method. (MDH)

Discusses a teaching method using investigational skills for Nuffield A-level Physics including assessment technique, change of the assessment criteria, advice for choosing the topic, and future development. (YP)

This sourcebook for chemical activities is designed to be used as a student laboratory book for both junior and senior high school students. The student's role as a knowledgeable consumer and informed citizen is stressed. Each activity includes a list of needed materials, procedures, reactions, questions, and notes for the teacher which include…
