Consider a toy factory where small pieces are assembled to make a complete toy. How would you relate this scenario to monomers and polymers?

• The small pieces are like monomers which are compounds, while the complete toy is like a polymer which is a molecule

• The complete toy (polymer) is made of small pieces (monomers) that connect together

• All small pieces (atoms) have two forms: monomer or a polymer

• The small pieces (polymers) connect together to form a bigger piece called a complete toy (monomer)
