Global Studies Seminar Series | Professor Robyn Eckersley and Dr Martin Mulligan
The new politics of climate change: building political momentum and community support for adequate action on climate change. In regard to responding to the enormous challenges of climate change, the public debate in Australia has been frustratingly narrow and yet polarising. The Rudd/Gillard governments have put nearly all their emphasis on the twice-defeated Emissions Trading Scheme (ETS) and an increased roll-out renewable energy alternatives, while the Abbott-led opposition has given new oxy

Guitar Building
In this class, students learn about physics principles by examining the physics responsible for producing music with electronic stringed instruments, while building, testing, and playing their own electric guitar. Students will design their own Guitar bodies, construct their own pick-ups, assemble their own guitars, tune them using a chromatic tuner, and use them to play a simple song. While the instructions here give enough detail that an independent learner could construct their own guitar, pl

Speed
The concept of speed is introduced to the inertia-mass relationship. Concept: Force varies with mass and rate of change of speed. Eureka was a series of short cartoons on physics that ran on public television in the 1980's.  The video explains the concept in simple and well illustrated way.  Good for students of any elementary school level.

Vectors
Physics must explain not only why and how much, but also where and which way. Physicists and mathematicians invented a way of describing quantities that have direction as well as magnitude. Laws that deal with such phenomena as distance and speed are universal. And vectors, which describe quantities such as displacement and velocity, universally express the law of physics in a way that
