The long chains of carbon that make up oils do not carry a charge and are not attracted to the water molecules.

When the bubbling stops replace the bottle cap. Alka-Seltzer is technically both acidic and basic. Furthermore, the oil will float on top of the water because it is 4th grade science fair projects dense than oil.

Add one piece at a time observing each reaction. Acid-base reaction — A chemical reaction between two substances where one is an acid and one is a base. See detailed discussion in Introduction section.

Select the food coloring accordingly. This creates the bubbles you see within the colored fluid in the soda bottle. The tablets contain sodium bicarbonate a base and citric acid an acid which, when mixed with water, react with each other and produce bubbling carbon dioxide.

Another good option is to cover a table with old newspapers. This causes the separation we see in this experiment as well as in our kitchen sinks and oceanic oil spills.

Terms, Concepts and Questions to Start Background Research Oil and water mixture — Oil, a hydrophobic compound, and water, a hydrophilic compound, do not mix.

Tip the bottle back and forth and observe the reaction. What happens when you add the food coloring to the bottle? Add water to the neck of the bottle, leaving a little space between the water line and the top of the container.

If making a large quantity of lava lamps you can order soda bottle performs in bulk at through a vendor such as: Research Questions What happens when you add water to the plastic bottle?

Gather materials over a surface that cannot be damaged by oil or can be wiped clean. What experiments did you perform on the closed soda bottle twisting, shaking, etc. To observe a chemical reaction between an acid and a base. Break the Alka-Seltzer tablet into smaller pieces 6 to 8.

Tip, twist, and shake the bottle in different directions. Add 10 or more drops of food coloring to the bottle until a rich color is seen. Observe the reactions and take notes. What did you notice during each trial?

What happens when you add the Alka-Seltzer to the bottle? You can always add more water at a later time. Why do you think this occurs?Jul 02,  · My son's grade 4 experiment presentation for his School Science Fair and he required an assistant which added a little more "entertainment".
