Strand 8.1: MATTER AND ENERGY INTERACT IN THE PHYSICAL WORLD

The physical world is made of atoms and molecules. Even large objects can be viewed as a combination of small particles. Energy causes particles to move and interact physically or chemically. Those interactions create a variety of substances. As molecules undergo a chemical or physical change, the number of atoms in that system remains constant. Humans use energy to refine natural resources into synthetic materials.

Standard 8.1.7

Design, construct, and test a device that can affect the rate of a phase change. Compare and identify the best characteristics of competing devices, based on data analysis, and modify them to improve the device to better meet the criteria for success. (PS1.B, PS3.A, ETS1.A, ETS1.B, ETS1.C).

• Transporting Natural Gas
  Students will investigate to determine the optimum conditions for phase change, using water as a model for natural gas.
