The activities in grades K-4, all students should develop an understanding of the science and technology in the field of plastics and polymers and their properties. The fundamental concepts and principles that underlie this standard include:

  • Objects have many observable properties, including size, weight, shape, color, temperature, and the ability to react with other substances. Those properties can be measured using tools, such as rulers, balances, and thermometers.
  • Objects are made of one or more materials, such as paper, wood, and metal.
  • Objects can be described by the properties of the materials from which they are made, and those properties can be used to separate or sort a group of objects or materials.



HOP science education investigation kits contain everything you need to design and implement a thorough and engaging investigation into the chemistry and the characteristics of plastics. The original HOP science curriculum kit was developed by the National Middle Level Science Teachers Association (NMLSTA), produced by the Plastics Division of the American Chemistry Council (ACC) and distributed by SPE to more than 30,000 teachers nationwide. A nominal charge for the kit materials and shipping can allow the Council to continue providing valued and long-lasting science tool.
