We are of course studying "Matter and Chemical Change" at the moment and we will be studying this right into February. Be sure to keep up with the work, as this unit will challenge you! We will begin our studies after the break by examining how avalanches are caused by the unique, and diverse physical properties of water (frozen water); If you would like to learn more about avalanches, please visit: http://www.avalanche.ca/ for online courses, bulletins and more!
