Techniques for Teachers Section
Peer reviewed Peer reviewed
Tait, A., Ed. – Australian Science Teachers Journal, 1973
Includes a simple technique to demonstrate Millikan's oil drop experiment, an environmental studies experiment to measure dissolved oxygen in water samples, and a technique to demonstrate action-reaction. Science materials described are the Pol-A-Star Tomiscope, Nuffield chemistry film loops, air pucks and pH meters. (JR)

The Continuous Variation Technique and Its Use in Schools
Peer reviewed Peer reviewed
Pendlebury, J. N. – Australian Science Teachers Journal, 1973
Describes how the continuous variation method may be used in senior chemistry classes at the secondary level. This technique allows for the detection of the one or more reactions that may occur in a system over a wide range of composition. (JR)

To Determine the Percentage of Copper in a Brass Screw Using a Computer Interface with a Colorimeter.
Peer reviewed Peer reviewed
Horgan, Joan; Hedge, Robyn – Australian Science Teachers Journal, 1997
Year 11 students investigated the real-world problem of whether screws are really brass. It allowed them to use the colorimeter and computer interface in a way that was easily understood and models normal practice in testing laboratories. Screws were dissolved in nitric acid and their absorbance of red light was compared with a standard curve.…

School Labs as Sites for Fraudulent Practice: How Can Students Be Dissuaded from Fudging?
Peer reviewed Peer reviewed
Ritchie, Stephen M.; Rigano, Donna L. – Australian Science Teachers Journal, 1996
Describes research that documents the falsification of laboratory results by chemistry and physics students. Discusses some factors that encourage students to fabricate results and why some students do not feel the need to falsify data. Contains 16 references. (DDR)
