We're digging deeper into exploring the properties of various chemicals. Each of the five unknown chemicals looks incredibly similar, so we're trying to find ways to find their unique characteristics.
We've used our eyes, our hands, and our noses. We are not using our sense of taste. Students have described the chemicals as powdery, slippery, smooth, grainy, ashy, sticky and even slightly odorous. Many of the chemicals share properties, which has gotten us thinking that we need to do further tests to distinguish one mystery chemical from the next!
