The Pond
Ponds offer a unique opportunity for scientific study. If you think of any key biological concept there’s a good chance you’ll find it illustrated in, or around a pond. They are fine examples of the biosphere in action. “The Pond” examines: community ecology, the importance of biological communities and how scientists work to understand complex scientific concepts by breaking things down into communities; food chains and food webs, including the complexities and problems of examining a food web; key biological process including photosynthesis, the oxygen/carbon cycle and energy transfer along a food chain; the importance of the detritus pathway; adaptations of and interactions between living organisms.

Properties of Waves
IIf the movement of a particle causes delayed movement in its neighbor we have a wave. Incorporating new graphics this updated video shows: transverse waves, tension waves such as ripples, gravity waves, longitudinal or push waves, shear and torsional waves; characteristics, amplitude, freq. vel. Period; V = nL is demystified with a passing train; velocity, refraction, reflection, superposition, diffraction interference and standing waves.

People of Porgera – 1984
This is the original film we made of the Porgera people in PNG before mineable gold was discovered. They show us their courting ceremony, a sing sing, marriage and bride price, wealth, debt and payback, salt, stone axes, trade, village court and prison system, what happens to wages from jobs with the mining exploration team, and talk about their hopes of wealth in the future.
