• Tools

• Conductors

• Blacksmith

• Teacher

• Astronaut

• Scientist

Circle all the ways heat can change an object.

• Raise temperature, object expands, physical change

• Fly, change state of matter, chemical change

• Raise temperature, fly, chemical change

• Object expands, fly, physical change
