General Science: Mixing Sulfur and Iron
This week we started learning some chemistry. Using a microscope and a magnet the kids explored the properties of 2 elements: sulfur and iron. Then they combined them and determined whether they had performed a physical change or a chemical change.
Here are some of the high points of their results:
iron: black, magnetic
sulfur: yellow, smelly, not magnetic
iron + sulfur: grayish yellow, smelly, BUT easily separated from each other with a magnet
Physical or chemical....you decide!
