Tech Lesson Idea

My first grade classroom is in the middle of a water unit which I am helping to teach. They are learning all about the different properties of water and how water can change from one state to another. I am hoping to use the digital thermometers to illustrate to the children how the change in temperature causes the water to change states form solid to liquid, liquid to gas etc. The students love doing hands on activities and would love to be able to further explore.
