Magic Milk Experiment: How-To Plus Free Worksheet - We Are Teachers - Free Printable

It looks like you've uploaded an image of a worksheet for the "Magic Milk Experiment", a classic science activity that demonstrates the effects of surface tension and fat molecules in milk when soap is introduced. However, the image shows only part of the worksheet — specifically, the supplies list, prediction section, before/after drawing areas, and partially visible instructions.

Let’s go through what this experiment is about and how to solve or complete it based on typical versions of this activity.

🔬 What is the Magic Milk Experiment?

This is a fun, colorful science experiment that shows how dish soap breaks down the fat molecules in milk, causing a dramatic swirling effect with food coloring.

---

✔ Supplies (as listed):

- Milk
- Dish soap
- Food coloring
- Bowl
- Cotton swab

---

🧪 Step-by-Step Instructions (Correct Order):

Here’s the correct sequence to complete the experiment:

1. Pour milk into the bowl (about ½ inch deep).
2. Drop food coloring into the milk (use different colors at different spots).
3. Touch the milk with the dish soap-covered end of the cotton swab.
4. Observe the reaction — watch as the colors swirl and dance!

> ⚠️ *Note: The worksheet says "Put the instructions below in the correct order." So if they're jumbled, here's the right order:*

- First: Drop food coloring into the milk.
- Second: Touch the milk with the dish soap covered end of the cotton swab.

---

🤔 Prediction Section:

You should write something like:
> *"I think the food coloring will stay in place until I touch it with the soap, then it will spread out and swirl around."*

Or:
> *"I think the colors will move quickly and make patterns when I add the soap."*

This prediction helps students think scientifically before seeing the result.

🖼️ Before Soap Drawing:

Draw where you placed each drop of food coloring in the milk. For example:
- A few drops of red, blue, green, etc., spaced apart in the center or around the edges.

---

🌀 After Soap Drawing:

After touching the milk with the soapy cotton swab, draw what you see:
- Swirling, explosive patterns.
- Colors moving rapidly outward from the point of contact.
- Possibly forming spirals or rings.

---

💡 Why Does This Happen?

- Milk contains fat molecules and proteins.
- These molecules are attracted to each other, creating surface tension.
- When you add dish soap, it breaks down the fat molecules.
- This causes a sudden disruption in the surface tension, pushing the food coloring away and creating the “magic” swirling effect.

✔ How to Complete the Worksheet:

| Section | What to Do |
|--------|------------|
| Prediction | Write your guess about what will happen when soap touches the milk. |
| Before Soap | Draw drops of food coloring in the bowl (e.g., red in top left, blue in bottom right). |
| After Soap | Draw swirling, colorful patterns radiating from the point where the swab touched. |
| Instructions | Order them: 1) Drop food coloring → 2) Touch with soap. |

🎉 Final Tip:

This experiment is great for teaching kids about chemistry, molecules, and cause and effect — all while being visually exciting!
