DC.5.5. Physical Science: Broad Concept: Energy and matter have multiple forms and can be changed from one form to another. As a basis for understanding this concept, students:
5.5.1. Recognize that all matter is made of small particles called atoms, which are too small to see with our eyes; describe how atoms may combine to form molecules or crystalline solids (compounds).
5.5.3. Explain that all matter is made up of an element, a compound, or mixtures of elements and compounds.
5.5.6. Explain that when a warm object and a cool one are placed in contact, heat flows from the warmer object to the cooler one until they are both at the same temperature. Know heat transfer can also occur at a distance by radiation.
5.5.7. Investigate and describe that some materials conduct heat much better than others, and poor conductors (insulators) can be used to reduce heat loss or gain.
