lava lamp observations

 a week ago we did a observation about lava lamps. when the aspirin is mixed with oil and water it makes a reaction because it is letting out all the carbon dioxide. What Happened... oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called “intermolecular polarity.” Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together (drops.) This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules, they get along fine as well. But the structures of the two molecules do not allow them to bond together.

When you added the tablet piece, it sank to the bottom and started dissolving and creating a gas. As the gas bubbles rose, they took some of the colored water with them. When the blob of water reached the top, the gas escaped and down went the water.

i found it hard to find all the science behind this observation but i worked hard and found the science behind it.

it was easy to see all of the reactions with the lamp because it worked like one and that was cool

learning about the science is always more interesting then the observation
