Engage/Activate Prior Knowledge
Before showing the video, ask students to list things they know about milk (color, taste, where it comes from, what you can do with it, etc.). Ask students if they've ever tried to mix anything in their milk. (Some may suggest chocolate or strawberry syrup.) We're going to watch a video to see what happens when we mix milk with food coloring and dish soap!

Video Description
Fill a plate with milk. Add 1-2 drops each of different colors of food coloring to the center of the plate. Coat one end of a cotton swab with dish soap and touch it to the surface of the milk in the center of the colors. Watch as an explosion of color moves outward through the milk. Version 7/2022<br>

StandardsThese activities support the following standards; additional materials will be required to cover the standard completely.
TEKS VI.A.1. Child observes, investigates describes, and discusses properties and characteristics of common objects. Background InformationMilk is made up mostly of water with fats, minerals, proteins, and vitamins spread throughout the mixture. The fats found in milk don't mix well with water, which is why the food coloring drops are able to sit without changing at the beginning of the demonstration. However, when soap is added, it links the water and fat molecules to each other. As the fat molecules are moved and connected, they cause the food coloring molecules to move as well. This leads to the explosion of food coloring that we see! Milk with greater fat concentrations lead to bigger color explosions because there are more fat molecules for the soap to link with water.<br>

StandardsThese activities support the following standards; additional materials will be required to cover the standard completely.
NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
NGSS 2-PS1-1: Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
TEKS 2.2A: Ask questions about organisms, objects, and events during observations and investigations.

_____________________________ Wow! How did soap do that? Let’s be science detectives and figure it out! Sometimes objects react with each other.
Physical properties describe an object. They are like clues to help us solve a mystery. One clue is whether something is a solid or liquid. The milk, dish soap, and food coloring are liquids. They take the shape of the container they are in. The plate and the cotton swab are solids. They keep their shape.
Another physical property is texture – how something feels. Close your eyes and imagine how the plate would feel different than the cotton swab. The plate is smooth. Your hands could glide over it easily. The cotton swab would feel soft and fluffy.
Another clue we can use is relative temperature. The milk is colder than the other ingredients. This tells us it was kept in a cold place. 1 2 3 4 5<br>

StandardsThese activities support the following standards; additional materials will be required to cover the standard completely.
NGSS 5-PS1-3: Make observations and measurements to identify materials based on their properties.
NGSS 5-PS1-4: Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
TEKS 4.2 C: Construct simple tables, charts, bar graphs, and maps using tools and current technology to organize, examine, and evaluate data.
TEKS 4.2 D: Analyze data and interpret patterns to construct reasonable explanations from data that can be observed and measured.
TEKS 4.5 B: Compare and contrast a variety of mixtures, including solutions.
TEKS 5.2 D: Analyze and interpret information to construct reasonable explanations from direct (observable) and indirect (inferred) evidence.
TEKS 5.2 G: Construct appropriate simple graphs, tables, maps, and charts using technology, including computers, to organize, examine, and evaluate information.
TEKS 5.5 B: Demonstrate that some mixtures maintain physical properties of their ingredients such as iron filings and sand and sand and water. Background InformationMilk is made up mostly of water with fats, minerals, proteins, and vitamins spread throughout the mixture. The fats found in milk don't mix well with water, which is why the food coloring drops are able to sit without changing at the beginning of the demonstration. However, when soap is added, it links the water and fat molecules to each other. As the fat molecules are moved and connected, they cause the food coloring molecules to move as well. This leads to the explosion of food coloring that we see! Milk with greater fat concentrations lead to bigger color explosions because there are more fat molecules for the soap to link with water.<br>

TEKS 4.5 B: Compare and contrast a variety of mixtures, including solutions.
TEKS 5.2 D: Analyze and interpret information to construct reasonable explanations from direct (observable) and indirect (inferred) evidence.
TEKS 5.2 G: Construct appropriate simple graphs, tables, maps, and charts using technology, including computers, to organize, examine, and evaluate information.
TEKS 5.5 B: Demonstrate that some mixtures maintain physical properties of their ingredients such as iron filings and sand and sand and water. Background InformationMilk is made up mostly of water with fats, minerals, proteins, and vitamins spread throughout the mixture. The fats found in milk don't mix well with water, which is why the food coloring drops are able to sit without changing at the beginning of the demonstration. However, when soap is added, it links the water and fat molecules to each other. As the fat molecules are moved and connected, they cause the food coloring molecules to move as well. This leads to the explosion of food coloring that we see! Milk with greater fat concentrations lead to bigger color explosions because there are more fat molecules for the soap to link with water.<br>

Use the plate below to show what happened in the demonstration. Draw four circles to show where the food coloring was added. Draw an X on the plate to show where the cotton swab was placed. Draw arrows to show which direction the food coloring moved. Did you know that your milk has fat in it? Milk is considered a mixture because it is made up of more than one compound, including water, fats, minerals, and more. Each of the compounds in a mixture keeps its physical properties. This means the compounds can be separated from one another.
Some mixtures are called solutions because the compounds are evenly dissolved throughout the liquid. Take salt water for example. If we put the salt water on a stovetop and boil it, we can separate the salt and water from one another.
Mixtures and solutions can be seen all around us. When we make powdered drink mix, we mix flavor powder, sugar, and water into a solution. Even the mixture of your milk can be different. Whole milk has the most fat while skim milk has no fat at all. You could even add flavored syrup to give a milk mixture another compound!<br>

Create a comic strip with at least four panels describing how to conduct the demonstration that you saw in the video. Each panel must have a complete sentence explaining what is happening and an illustration that includes labels for each material. Do you know someone who is lactose-intolerant? You may know that this person can’t drink milk, but what exactly does this mean?
In milk, there is a natural sugar called lactose that our bodies can use to give us energy. All sugars are made up of the elements carbon (C), oxygen (O), and hydrogen (H), but the structure of the atom varies, depending on what kind of sugar it is. To make lactose, there must be 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. The chemical formula for lactose looks is C12H22O11. Notice the subscripts that are written after each symbol. This is where you see how many atoms of each element are needed.
When people who are lactose-intolerant drink milk or eat milk products like cheese or ice cream, their body is unable to break down this type of sugar. Because they are unable to digest the lactose, their body tries to get it out of the digestive system as soon as possible. Lactose-free products like almond milk and coconut milk are good alternatives for some people who are lactose-intolerant.<br>
