Materials: What Is the World Made Of? by Kathleen Weidner Zoehfeld
Read pages 12-13 in the book, What Is the World Made Of? Ask your child to describe what a liquid is. Review the properties of liquids.
  • Liquids have no shape of their own. They take the shape of whatever they are in.
  • Liquids can be poured.
Tell your child that some solids can be poured, such as salt or sand. They are not liquids, however, because they are made up of tiny little pieces that keep their shape. Liquids do not keep their own shape.
