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! |

Mrs. BrinzaWe always practice safe science in our room. We wear goggles to protect our eyes, never touch anything that is unsafe, and keep the aisles clear so we can freely and safely move around the room. Archives
