Yesterday, we analyzed a piece of steel wool and described its characteristics. We then put a few drops of water on a small portion and let it sit over night. Today we observed the chemical change that has occurred. The students hypothesized that the steel wool will change colors based on their experience with using the steel wool to wash dishes. This was followed with a discussion about oxidation and chemical reactions. Students observed that their hypothesis was correct because it changed colors. They also observed that the metal itself was changing shape. We were not able to use the microscope because it is not working but we were able to take some pictures using the Miscope. When we receive a new microscope, we will do it again. We are also going to add liquid soap and water to the already oxidizing piece and make observations tomorrow.
