This activity is more concerned with illustrating the process of scientific discovery than with astronomy. Students are involved in observing the Moon and noting the simultaneous location of the Sun. A manual with observation log and diagrams is provided. Requires no special equipment and takes a discovery learning approach. (LZ)

Activities involving concave rubber disks are utilized to illustrate the scientific principles of kinetic and potential energy. Provides teacher instructions and questions related to the activity. (MDH)

Considers the ways in which students' activities during project work are influenced by their images of science. Finds that the concept of "epistemic demand" may help in anticipating difficulties students might have during science project work, and that students' images of science are developed as a result of implicit and explicit…

In September 2002, Salter's Nuffield Advanced Biology ("SNAB") began a three year pilot phase in schools, representing the first major innovation in UK biology education since the 1970s. One part of the AS level coursework was a report on an "Issue of Biological Interest". This could be based on an actual visit outside school…

Offers suggestions for activities that demonstrate the principles of osmosis. Explains how decalcified chicken eggs can be used to give students practice with measurement, experimental procedures, and science principles. (ML)

Discusses the use of a modified electron spin resonance apparatus to demonstrate some features of the expression for the transition probability per second between two energy levels. Applications to the third year laboratory program are suggested. (CC)

Introduces a method for two-dimensional kinematics measurements by hanging marbles with long strings. Describes experimental procedures for conservation of momentum and obtaining the coefficient of restitution. Provides diagrams and mathematical expressions for the activities. (YP)
