Expansion and Contraction of Materials

Time Frame:
1 class period that runs 45 minutes.

Group Size:
Large Groups


Using bimetal strips and Ball & Ring show how materials expand and contract with heat.

Main Curriculum Tie:
SEEd - Grade 6 (2017)
Strand 6.2: Energy Affects Matter 6.2.3

Plan and carry out an investigation to determine the relationship between temperature, the amount of heat transferred, and the change of average particle motion in various types or amounts of matter. Emphasize recording and evaluating data, and communicating the results of the investigation.


  • bimetal strips
  • ball & ring
  • heat Source (Bunsen burner, alcohol lamp or hot water)
  • ice Water
  • worksheet


Student Prior Knowledge:
All matter is made of particles. Particles move. They move faster with more heat.

Instructional Procedures:
This can be done as a demo or as a student experiment depending upon your equipment. You could have i/2 of the class working on the Ball & Rings and the other 1/2 using the Bimetal Strips.
