STEM CONNECTIONS

In the STEM Plastics course, students discover how the four disciplines connect as they convert plastics into finished products.

Science

  • Monomers
  • Polymerization process
  • Chemical reactions
  • Elements
  • Atoms
  • Periodic table
  • Molecular weight
  • Covalent bonds
  • Chemical and physical properties

Technology

  • Windows-based graphical user interface
  • Injection molding machine
  • Vacuum forming machine

Engineering

  • Design and development of parts and products
  • Design evaluation and design changes to improve products
  • Engineering design process

Math

  • Units of measurement
  • Ratios and proportions

STEM PLASTICS

The purpose of the STEM Plastics course is to provide students the opportunity to demonstrate two processing methods used to convert plastics into finished products. Students will be challenged to design and prototype products by taking on the role of a plastic component/product designer. They must adhere to the specifications and constraints given and explore the chemistry of plastics in order to understand its qualities and be able to select the correct material and process required to produce specific products.

Upon completion of the STEM Plastics course, students will be able to:

  • Identify the two types of change in matter
  • Recognize the properties of polymers
  • Explain polymerization
  • Identify the different types of plastics and applications
  • Differentiate between thermoplastics and thermosets
  • Identify the structure of molds (or tools)
  • Explain the injection molding technique
  • Operate an injection molding machine
  • Discuss the vacuum forming process
  • Operate a vacuum forming machine
  • Apply the engineering design process
