G4 - Emulsion

They are chemical substances, natural or artificial, made up of molecules with a head that loves water (hydrophilic) and a tail that, instead, hates water (hydrophobic) called surfactants. These molecules are called surfactants, they are very contained in soaps and detergents. The surfactant molecules facilitate surface wettability and miscibility between different liquids. Another example of an emulsion is mayonnaise. It is an emulsion of oil dispersed in the water contained in the yolk made up of two immiscible liquids in which one of them is found in the form of very small drops (dispersed phase) in another liquid which acts as a continuous phase, also called dispersing phase.

SCRIPT

M and MC are fighting

E: shut up and stop fighting! Why are you fighting in the first place?

M: Because, in my opinion, I am better at cooking!

MC: That’s not true, you don’t even know how to cook pasta!

E: I suggest we have a cook off to see who’s best!

M: I agree.

MC: I agree too, even though I’m going to win anyway

A:Let’s see what topic comes out….. It's an emulsion!

A: You know what emulsion is, right?

MC: Yes! Emulsion is a mixture of two unmixable substances (if you mix them together), of which one is in the form of tiny drops.

A: Great explanation!

E: Can you tell me an example of emulsion?

M: Yes, oil and wa-

MC: Water! (M sighs) They are an emulsion because you can’t mix water and oil but if you shake the container very violently, the oil will turn into small drops and slowly separate from the water.

A: Great, let’s start the challenge. The two of you have your own work stations (M and MC go to their spots) with all the ingredients to cook an emulsion. 3 2 1...start!

MC and M start to cook

E: (goes to MC) Do you have an idea of what to cook?

MC: Yes, I’m going to make some nutella!

E: (goes to M) and what about you? Do you have an idea of what to cook?

M: Hmm, I’m actually not sure but I think I’ll make some mayonnaise!

A: Great, you can continue!

*ten thousand years later*

A: (Goes to MC) Can you tell me more about the water and oil mixture you were talking about earlier?

MC: ….yes, that emulsion was an unstable type, what this means is that after a while the water and the oil will separate and all of the bubbles will go away!

A: And how do you turn an unstable emulsion to a stable one?

MC: By making use of tensioactive substances, of course! They facilitate wettability or surfaces and miscibility between different liquids... in mayonnaise substances do not separate because it’s got the egg inside, which is a tensioactive substance!

A: (nods his head and goes to M) how’s it going here? Did it emulsify?

M: No, it hasn’t yet but I’m sure it will soon!

E: I think that this is because you’re mixing too slowly and because of this you can’t separate the oil, and so you aren’t making the drops!

M: So do I have to put the ingredients in quicker?

E: No, you don’t, because if you do, you’ll find yourself unable to create drops. The only thing you have to do is mix the mayonnaise quicker

E and A: (looks at the clock) aand 5, 4, 3, 2, 1. Stop cooking and bring your plates to Enrico

M and MC: (when A says 2) We’re finished!!

E: great, I hope they are good! (improvise from here and choose the winner)

WHAT WE DID

storyboard
tried the experiments
corrected the script

MATERIAL

EXPERIMENTS

In doing the experiments we decided to remove the hazelnut cream and prepare 2 mayonnaise so we corrected the script.

MC starts to cook.

E: (goes to MC) Do you have an idea of what you can cook?

E: great, I hope they are good!

E: Wow MC, your plate looks and tastes really good, I think I’ll have to give you an 9/10.

MC: Wow! I can’t believe it! I thought I would’ve gotten 7/10.

E: On the other hand I think I’ll have to give you a 3/10 M.

M: What? Why! I thought I did way better than MC!

E: It’s because the taste is horrible and it didn’t actually emulsion.
