Does this mean the oil and water mix or not mix (separate)?
Do you observe (see) layers?
Does this mean the oil and water mix or not mix (separate)?
Now we are going to look at the oil and water (vinegar) mixtures at the nanoscale (molecules)
Does this model show vinegar molecules and oil molecules attracted (combined, connected) to each other?
Does this model show the oil and vinegar (water) molecule mixing or not mixing (staying separate)?

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.
