I've got the Power!
Playing around with aspects of electricity never ceases to be something students love doing in the classroom. I think that in such a technologically enhanced society, we can overlook the simple brilliance, pleasure and awe that can come from looking at the basic components and principles of electrical circuits.
The potential for great tinkering, creation and exploration with electronic materials is limitless. In the mid-1990s, I remember the joy and fascination of the experimenting with the Dick Smith 'Fun Play' electronic kits. These kits provided a detailed way for children to develop an understanding of how circuits worked. There is now an abundance of similar kits to be found in stores like JayCar for students to tinker and play with, but they just don't have the same appealing simplicity of those kits from yesteryear.
