Geology

From vacuum to volcanoes - nature's drive to mix it up!

Submitted by Anonymous (not verified) on

Making matter move is nature's way of mixing it up and allowing chemical, electromagnetic, electrostatic, and gravitational interactions to occur. We'll demonstrate movement due to changes in vacuum conditions, formation of magnetic fields from inductive currents, and volcanic action. We will use a vacuum cannon, electromagnetic can launcher, and a demonstration of the coldest volcano on earth to show how nature mixes it up!

Biodiesel & Algal Studies Group

Since 2009 Castle Park High students, with Dr. Pomeroy of UCSD, have learned to produce biodiesel from vegetable oil. Students use a particle counter to determine how “clean” the fuel burns and discuss how particulate impacts our global climate. Students present this field data to support the benefits of biodiesel. Our booth, as in years past, will demonstrate the step-by-step process of biodiesel synthesis, discuss the advantages of biodiesel over petroleum and outline the ease of production.
