Sorry about the delay in this article…
Two weeks ago, second grade students started a big investigation project about the Global System of Chemical Labeling. These little labels are meant to be a warning sing to cry our attention when we are about to use a chemical product.
We are now ready to hang our good jobs on Lab’s walls and from now on we will never forget the meaning of these pictures when we use our daily but dangerous products.
