Density Column

Pour liquids and drop objects into a tall column. See how density decides where everything ends up.

How to use

  1. Explore: press a liquid to pour it in any order. Then drop objects in. Turn on Show particles to zoom in.
  2. Predict: place each liquid name on its layer. Drag a name, or tap a name and then tap a layer.
  3. Where will it go? Answer 6 questions about where an object stops. You get one retry on Predict and on each question.
  4. Press Show my results at the bottom and copy them onto your worksheet.

What is happening

Why does this happen?

Density is how much mass fits in a certain volume: D = m / V. Every layer in this column is the same volume, 50.0 mL. But the particles are packed close together in a dense liquid, so that same volume holds more mass. A liquid with more mass in the same volume has a higher density, so it sinks below the others. An object floats on any liquid that is denser than it is.
