Emulsifier Review - Observable Scale (What you can see)

Oil and Water (Vinegar) Mixture

1

Do you observe (see) layers?

1

Oil, Water (Vinegar) and Lecithin Mixture

1

Do you observe (see) layers?

1

Nanoscale - Too small to see (atoms and molecules)

Now we are going to look at the oil and water (vinegar) mixtures at the nanoscale (molecules)

Oil and water (vinegar) BEFORE adding Lecithin

1

Does this model show vinegar molecules and oil molecules attracted (combined, connected) to each other?

1

Does this model show the oil and vinegar (water) molecule mixing or not mixing (staying separate)?

Emulsifier Model

1. Choose one shape to represent each kind of molecule and drag each shape to the Key.

2. In the large box representing the mixture in the cup, create a nanovision model of an emulsifier.  From the bottom of the screen, drag shapes you chose to the mixture in the cup.

What does the Emulsifier Model show?

Sentence starter: The emulsifier model shows ______________________________

1

Oil molecule is ____________________________ to vinegar molecule

1

Emulsifier molecule is ____________________________ to vinegar molecule

1

Emulsifier molecule is ____________________________ to oil molecule

Evaluating Models of Emulsifiers: We are going to evaluate (look/grade) the sandwich model and the surrounding model to see which emulsifier model is more correct.
