Solids, Liquids, and Gases

Solids, Liquids, and GasesImagine a test tube as large as your students, and watch as the solid and liquid inside react and become a gas... What happens when a balloon is fitted over the top? Introduce your students to the science of chemistry through the use of some unusual demonstrations. Invite students to explore the properties of solids, liquids and gases and how energy changes matter from one state to another.

Program Options: Solids, Liquids, and Gases is available only as a large group assembly.

Assembly Option

ASSEMBLY MAX: 250 students
TIME: 50 minutes
GRADE: Grades 3-5



  • To demonstrate the three phases of matter.
  • To introduce energy as a concept different from matter.
  • To introduce the scientific method by having students predict results of experiments, perform experiments and notice outcomes.
  • To offer a working model of atomic behavior as it relates to phase change.
  • To demonstrate phase change.


Physical Science - Distinguish between solids, liquids and gases in terms of shape and volume. - Describe how the states of matter change as a result of heating and cooling. - Identify evidence of physical changes, including changing phase or shape, and dissolving in other materials. - Use the relationship between heat and the motion and arrangement of particles in solids, liquids and gases to explain melting, freezing, condensation and evaporation.
