Color Changing Milk: A Fun Science Experiment for Kids

The video tutorial demonstrates a simple science experiment using milk, food coloring, and soap to illustrate the concept of surface tension. It guides viewers through the setup, execution, and observation of the experiment, explaining how soap interacts with milk to create colorful patterns. The tutorial also discusses the practical applications of this phenomenon in cleaning and stain removal.

What is the primary educational value of the milk and soap experiment?

• It demonstrates the properties of solid materials.

• It explains the process of evaporation.

• It shows the effects of temperature on liquids.

• It illustrates the liquid properties of milk, coloring, and soap.

Which of the following is NOT required for the milk and soap experiment?

• Dishwashing liquid

• A shallow water container

• A camera

• A microwave

What should you do after adding food coloring to the milk?

• Stir the milk vigorously.

• Add dishwashing liquid using a cotton swab.

• Heat the milk.

• Freeze the milk.

What property of liquids is primarily responsible for the color spread in the experiment?

• Viscosity

• Buoyancy

• Surface tension

• Density

How does soap affect the surface tension of milk?

• It breaks the surface tension.

• It has no effect on the surface tension.

• It increases the surface tension.

• It solidifies the milk.

What happens to the milk fat component when soap is added?

• It separates.

• It evaporates.

• It solidifies.

• It becomes more viscous.

How does soap help in cleaning according to the experiment?

• By making water more acidic

• By increasing the temperature of water

• By breaking the surface tension, allowing stains to slide off

• By changing the color of stains
