Gypsum is a soft mineral that is white or gray and feels smooth to the touch. 🏞
️ It is made from calcium, sulfur, and oxygen. Found in places like the United States, Canada, and Britain, gypsum is commonly used in making buildings, like your classroom! 🏫
When heated, it turns into a powder, and when mixed with water, it becomes hard again! This process helps create many products we use every day, like chalk and drywall. Gypsum is very important because it helps make our homes safe and strong. 🌍
