Color Density Tower: Simple and Easy Science Experiments for Kids to do at Home
Explanation: In this experiment, when we add the same amount (same volume) of two different liquids they will have different weights because they have different masses. The liquids that weigh more (have a higher density) will sink below the liquids that weigh less (have a lower density).
The same principle goes for the small objects that you dropped into your density tower. The metal bolt is denser than all the liquids in the tower and therefore sinks directly at the bottom. For example, the ice-cube is denser than alcohol and less dense than water. This makes the ice-cube settle on the top of the layer of water.
We had grabbed a bunch of miscellaneous objects to drop into our density tower. This is the perfect opportunity to get into some scientific exploration!! Use items like- bolt, ping-pong ball, grapes, cashew nut, etc. into the container and try it out with many such items. Analyze where do the objects float and why!
