Lava Lamp Experiment

What materials are needed for this project?

• Water Bottle, Oil, Food Coloring, and Alka Seltzer

• Water Bottle, Oil, and Alka Seltzer

• Water Bottle, Food Coloring and Alka Seltzer

• Water Bottle, Oil, and Food Coloring,

What is the purpose of adding food coloring to the water in the jars?

• To make the oil change color

• To make the water visible and distinguishable from the oil

• To help the Alka-Seltzer tablet dissolve faster

• To increase the temperature of the water

Why is it important to fill the jars at least three-quarters full with vegetable oil?

• To ensure the Alka-Seltzer tablet reacts with the oil

• To prevent the water from evaporating

• To create a clear separation between the oil and water layers

• To make the jar heavier

What is the role of the Alka-Seltzer tablet in this experiment?

• To change the color of the oil

• To create bubbles and simulate a lava lamp effect

• To heat the water

• To cool the water

How much oil was needed for this project?

• five-quarters

• three-quarters

• four-quarters

• two-quarters

How should you prepare the Alka-Seltzer tablet before using it in the experiment?

• Crush it into a fine powder

• Cut it into quarters

• Dissolve it in water first

• Use it whole

What happens to the Alka-Seltzer tablet when it reaches the water in the bottle?

• It dissolves and releases gas bubbles

• It changes the color of the water

• It floats on top of the oil

• It sinks to the bottom without reacting

What is the main scientific concept demonstrated by this experiment?

• The effect of temperature on chemical reaction rates

• The solubility of oil in water

• The effect of color on reaction speed

• The density difference between oil and water

Why is it necessary to use a transparent bottle for this experiment?

• To allow light to pass through and heat the contents

• To observe the reaction and the movement of bubbles

• To make the oil and water mix better

• To prevent the jar from breaking

Water and ___ didn't mix together.
