The density tower is a simple and fun experiment that can be used to demonstrate the concept of density. In the STEM Competition, the students of Sekolah Rendah Rafflesia Kajang used this experiment to show how different liquids can be layered according to their density. Substances that are more dense create the base of the tower, while substances that are less dense seem to float in the middle and on top.

This experiment was a great way for the students to learn about density. They were able to see how different liquids can have different densities, and how this affects how they interact with each other. The density tower is a fun and engaging experiment that can be used to teach students about a variety of STEM concepts.
