East Elementary students were treated to some very exciting Science experiments today thanks to Miss Kruse who brought in a guest from Concordia University of Edmonton!  Dr. Woollard showed us a variety of experiments!  Favourites were the purple gas created by a mixture involving iodine, the fire created when he mixed permanganate and glycerol,  and for sure- the freezing of lettuce in the liquid nitrogen container!  Visit our FB page for more pictures.
