Based on the picture above, when a salad dressing stays mixed, we refer to it as a ___________ mixture.

Based on the picture above, when a salad dressing separates, we refer to it as a ___________ mixture.

There are ingredients, known as texture ingredients, that cause liquids that normally don’t mix, to mix and become a stable mixture. These ingredients are called emulsifiers.

Drawing Nanovision Models of Emulsifiers

Go to the MM 3.5 Model in Google Classroom, Science, Classwork

0

Go to google classroom and make your model to show what happenes when an emulsifier (lecithin) is added to oil and vinegar.

- Take a screenshot and add it here to show your work.

Steps to get to the Simulation
1) Go to Clever
2) Go to the Amplify Science App
3) Click on Modeling Matter
4) Orange number 1 - Modeling Matter
5) Click on the 3 lights in the upper left corner
6) Choose Emulsifier

1

Trial 1: Add molecule 5 and molecule 6 in the dish. Are they attracted to one another and mix?

1

Trial 2: Add molecule 5 and molecule 6 in the dish. Now add the emulsifier molecule. Mix them with the help of an emulsifier. Are they attracted to one another and mix?

0

How did the emulsifier’s shape help to mix the molecules?
