1. Homemade vs. Store Bought Lava Lamps What’s the Difference? By Grant Larson, Josseline Acosta, Molly Baldwin, and KhalilBingmon Lesson Overview and Reflection Product: Lava Lamps Essential Question: What's better, store bought or homemade? Story Narrative: Lava Lamps are inspiring. Assessment Used: Reflection: Store Bought: Store bought lava lamp’s ingredients are trade secrets of the chain manufacturing them, but the original lava lamp was made with paraffin. Paraffin is a type of wax that is a hydrocarbon, meaning that it is made up of hydrogen and carbon. Paraffin is less dense than Water when it is in both solid and liquid forms. Which means that it floats no matter how hot and melted or cold and solid it is. So the paraffin is mixed with chlorine to increase it’s density, so it is weighed down. When the lava lamp turns on, the light acts as a heat source. This causes the paraffin to be less dense than the water, so it breaks away and slowly rises to the top. When it reaches the cooler water at the top of the lava lamp it transfers enough heat that it sinks back to the bottom. Homemade: To make a lava lamp you have to fill a bottle about 7/8th of the way full with vegetable oil. Then you add about 1/8th of colored water. To start the bubbly part of the lava lamp you got to drop a Alka-Seltzer tablet or a form of antacid-pain relieving tablet into the bottle.

Materials 16.9 fl. Oz. Water Bottle 12 gl. Oz. Vegetable Oil Alka-Seltzer tablets (3) Water (4 fl. Oz. ) Store bought lava lamp What to do Pour 12 fl. Oz. of vegetable oil into the water bottle Then pour some food coloring (3 drops) Drop an Alka-seltzer (2) Be amazed Our 3 Big Ideas A solute is a substance that dissolves in a solvent to create solutions. Solubility is the property of solutes to dissolve in a solid, liquid, or gas solvent to form a homogeneous solution of the solute in the solvent Paraffin has a density of 900 kg/m³.Water has a density of 1000 kg/m³. Paraffin is less dense than water, so it floats until it gets mixed with chlorine. Chlorine weighs it down. How this Activity Demonstrates them The CO2 bubbles simulate paraffin that floats to the top of a lava lamp when heated. The sinking bubbles simulates when the paraffin reaching the cooler water when it reaches the top. The oil simulates paraffin The H2O sinking beneath the oil represents the paraffin sinking Paraffin is a type of wax that is a hydrocarbon
