Big Ideas
- Heat can change materials in different ways—sometimes these changes can be undone, and sometimes they cannot.
- Understanding which changes from heat are reversible helps us make sense of physical and chemical changes in everyday life.
Essential Questions
- What happens to materials when heat is applied?
- Can all changes caused by heat be undone? Why or why not?
- What is the difference between melting butter and cooking an egg?
- How can we tell if a change from heat can be reversed?
- Where do we see reversible and irreversible changes caused by heat in daily life?
