Viscosity of Liquids

🧪Lab Brief #8

Matter and Atoms.

🎯 Your mission

Master the concept. Use it tomorrow.

⚡ The twist

Color changes mean atoms are rearranging — even if you can't see them.

🤯

Mind = Blown

🧪 If you could remove all the empty space from atoms, the entire human race would fit in a sugar cube.

🔮

Make a hypothesis first

Before you mix: what color do you think it'll turn?

What You'll Learn

Viscosity measures how easily a liquid flows. Thick liquids like honey and syrup have high viscosity and pour slowly, while thin liquids like water have low viscosity and flow quickly.

Key Words

Tap a word to see its definition.

Steps

Step 1Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2Do

Create a density column: carefully layer honey, dish soap, water, vegetable oil, and rubbing alcohol in a tall glass. Drop small objects in to test where they float.

Step 3Observe

Watch carefully for any changes and note the time.

Step 4Record

Create a data table to organize your measurements.
