DIY lava lamp

Science

• The child learns about density and how different liquids have different densities as they observe the oil floating on top of the water in the lava lamp.
• They learn about chemical reactions as they observe the interaction between the water, oil, and effervescent tablet, causing bubbles and the movement of the oil.
• They learn about states of matter as they see the water changing from liquid to gas as it reacts with the effervescent tablet.
• The child learns about the concept of buoyancy as they observe the oil floating on top of the water due to the difference in densities.

For continued development, encourage the child to experiment with different colors and types of oil to see how they affect the lava lamp's appearance. They can also try using different materials to create the lamp, such as a plastic bottle or a glass jar, to see how it changes the overall effect.
