Lesson overview

What students will learn

  • I can describe observable properties before and after a change.
  • I can tell when an object changed shape or size but is still made of the same material.

Key science ideas

  • Folding, bending, or tearing can change an object's shape or size.
  • A torn paper strip is still paper even though the pieces are smaller.
  • Wetting paper adds water and may change its flexibility or strength during the test.
