Casein polymer Experiment

What is the name of the monomer used to make casein polymer?

• Milk

• Ethene

• Casein

• Protein

In your milk polymer experiment, vinegar was added to...

• Increase the pH of milk, making it more acidic

• Increase the pH of milk, making it more alkaline

• Decrease the pH of milk, making it more acidic

• Decrease the pH of milk, making it more alkaline

What piece of equipment was not used in this experiment?

• A funnel

• A condenser

• A beaker

• An electric hot plate

Are plastic (synthetic) polymers usually good for the environment?

• No

• Yes

• I don't know

Milk polymer is an interesting polymer because it is:

• Made from non-renewable resources (at some point there will be no resource to make it anymore)

• White

• Made from renewable resources (we can always produce more)

• Hard when dry

Did you find the milk experiment... (you can choose multiple answers)

• Boring

• Too simple

• Interesting

• Can I eat the polymer I made today?
