Construct and interpret models that illustrate features of the Earth. Infer how human behavior, such as farming, mining, and construction, changes the Earth's surface. Some common materials, such as water, can be changed from one state to another by heating or cooling . Compare the unique properties of water with other substances as they are heated and cooled. Heat can be produced in many ways, such as burning and rubbing or mixing one substance with another.
Heat can move from one object to another by conduction .
Explore and describe how heat moves from one object to another. Investigate and describe what materials can be used to prevent heat from moving from one object to another, such as insulators, and apply to real world examples. Describe ways to stop a fire from burning. The position and motion of objects can be changed by pushing or pulling. The size of the change is related to the strength of the push or pull .
