Polymer - Engineering Grade 8

Polymers are material made up of repeating units called...?

• 
  electrons

• elastomers

• monomers

• monochromes

The word polymer comes from the Greek meaning...?

• twisted

• bonded together

• together by choice

• many parts

All polymers are synthetic.

• True
• False

True or False: Proteins are a type of synthetic polymer.

• True

• False

Define polymer

• short molecule made of a few repeating units

• circular molecule made with many repeating units

• long, chain-like molecule made of repeating units

• chain-like molecule that contains hydrogen and oxygen

An example of a natural polymer is:

• PVC (polyvinyl chloride)

• protein

• polyethylene

• PET

Crosslinking is commonly used in rubber (like rubber bands and tires) to .....

• 
  make it more colorful

• increase elasticity

• increase durability

• make it weaker

Borax adds crosslinkers between different polymers within the glue. Add more borax .......

• to creates a tighter network that is better for

  bouncing.

• allows the

  material to stretch, like slime

The monomer of the polyethylene is....

• Propane

• Ethene

• Ethane

• Propene

• b)

  synthetic polymer

• c)

• d)

  protein
