A particularly interesting topic

We have started into term 2 by looking at the "particularly" interesting topic on the Nature of Matter. We have been discussing the arrangement of particles in solids, liquids and gases and how this affects their properties. We have then extended these basic concepts to discuss expansion, contraction, diffusion, pressure and changing states. The picture above shows one of the experiments we did looking at diffusion of colour (from pebbles) in water.
