By: Eve Campbell Lava Lamp Science Fair Experiment Hypothesis: My hypothesis is that if i mix oil and water, then it will make bubbles from the gas at the top. Then the bubbles will just keep going to the top and back down. Materials to make this experiment: A clean 1 liter soda bottle 3/4 cup of water vegetable oil fizzing tablets (alka seltzer) food coloring Steps pour the water into the empty liter bottle. slowly pour the vegetable oil into the bottle, until almost full. (you may have to wait until the water and oil separate) add 10 drop of food coloring. break a alka seltzer tablet in half and drop it in. Observations! When i added the tablet piece it sank to the bottom, dissolving and creating a gas. As the bubbles came up they got the colored water in them, the bubble got to the top and the gas escaped and then the bubble went back down. Conclusion My hypothesis was right, because the oil didn't sink it came up and went back down making all of the bubbles. The reason the oil and water do not mix, is because the the oil is less dense. (intermolecular polarity) Demonstration: purpose The purpose for my experiment is, to find out what happens when i mix different elements. My main question i am trying to solve, is to see if the water and oil will mix together. ScienceBob. "How to Make a Lava Lamp the Easy Way." YouTube. YouTube, 11 Dec. 2008.

Experimental design Independent variables: oil, water, 1 clean liter bottle, and alka seltzer

Dependent variables: a light and food coloring Bibliography: Galgas, Steve. "Blobs in a Bottle, The World's Easiest Lava Lamp - Science Bob." Blobs in a Bottle, The World's Easiest Lava Lamp - Science Bob. Science Bob, 2012. Web. 15 Nov. 2012. <http://www.sciencebob.com/experiments/lavalamp.php>.
