Changes Caused by Heating
Supporting
TEKS Objective
The student is expected to predict, observe, and record changes in the state of matter caused by heating or cooling.
Essential Understanding
The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used.
Science Background
Heat Required to Turn Ice into Steam: School for Champions (website) - Energy must be expended to change from a solid to a liquid state. Learn how much heat is necessary to raise the temperature of ice to its melting point.
Calorimetry: The Physics Classroom (website) - Detailed explanation of how heat changes the states and properties of matter.
Signature Lesson
Melting and Freezing: Science NetLinks (website) - Students predict, observe, record and describe how melting and freezing impact three everyday items (water, chocolate, and margarine), and discover that a substance’s volume and weight remain constant when it changes from a solid to a liquid, or vice versa.

Melting Ice: Government of Western Australia (PDF) - Students investigate the link between global warming and melting ice caps.
Assessment Ideas
Have students write paragraphs describing the changes they observe while an ice cube melts.
