Properties of Substances

In science, we have been working on characteristics of substances.  How scientifically, we can look at texture, flexibility, buoyancy, colour, hardness, strength, solubility and mass to categorize different substances.  Today in class the students were given different substances and they had to categorize or discribe each by the given descriptors.  The students had a tendancy to want to label or identify the substance, they needed to be reminded that, that wasn't today's job.
