What Does It Mean? 🤔
Let's learn together
🍯
Not all liquids weigh the same for the same amount of space. Some liquids, like honey, are very densely packed. Others, like rubbing alcohol, are much less densely packed. This is called liquid density.
When Fix poured honey, dish soap, water, oil, and rubbing alcohol into the same cup, they did not mix together. Instead, they sorted themselves into layers from densest at the bottom to least dense at the top!
This layering happens with liquids in nature too. In the ocean, denser saltier water sinks below less dense water, creating layers that affect ocean currents all around the world.

Real examples
🍯
Honey sinks all the way to the bottom because it is the densest liquid!
🛢️
Oil floats near the top because it is less dense than water!
🌊
The ocean has layers of different density water, just like the layer tower!

👨👩👧 Teaching Tips
This word builds directly on Density — use the same layer tower demonstration but ask kids to predict and then explain the order specifically for liquids, reinforcing the concept from a new angle.
🏫 Classroom Ideas
After building the density tower, have students draw and label the layers from top to bottom, identifying which liquid is densest and which is least dense.
