Liquid Density
1. Explain that Density, is mass per unit of volume and can be visually demonstrated. 2. It is a physical property of matter3. learn to predict the behavior of the materials based on their density
This project will clarify that when two or more liquids of different densities when are mixed together they will always remain separated. This project will illustrate the phenomenon of how different liquids react with water.
• Tall clear cup
• Plastic cups
• Water
• Rubbing alcohol
• Turkey baster
• Blue Dawn dish soap
• Honey
• Light corn syrup
• Blue food coloring
• Vegetable oil

Step 1: Pour some rubbing alcohol into a plastic cup and place a few drops of blue food coloring into the cup until the liquid turns dark blue. Pour some water into a second plastic cup, and place green food coloring into the cup. Pour some corn syrup into a third cup and pour orange food coloring into it.

Step2: Pour a thin layer of honey into the tall clear cup.

Step3: Sowly pour the corn syrup into the tall cup.

Step4: Next, add the dish soap mixture into the middle of the tall cup.

Step5: Add the water to the tall cup using the turkey baster.

Step6: Next, pour the vegetable oil into the tall cup.

Step7: Lastly, add the rubbing alcohol into the tall cup using the baster. You should now have 6 different layers of liquid.

1.While doing the activity ask children- What are they seeing?
2.Why do they think liquids are not mixing?
extra information to be shared:
Corn syrup: 1.37. Water with food coloring: 1.00. Rubbing alcohol: 0.87. Dish soap: 1.03. Honey: 1.36. Vegetable Oil: 0.91. The varying densities allow you to form layers of liquids on top of each other, creating the visually stimulating display in your glass.
3. Why does ice float in water?
4.Summarize the results of the experiment. How does density affect the position of a liquid relative to other liquids?
5. Can you think of an example from daily
life where you have observed liquids with different densities interact?
What does this say about their relative densities?
Accurate, Clearly explained, Knowledgeable, Methodical, Precise, Informative

Some of the brainstorming questions can be given as exercise to be done at home too.
