  1. Question #1: What will happen when we mix two liquids- water and oil? LAVA LAMP EXPERIMENT • Materials: • Water • Oil • Bottle • Alka-Seltzer Tablet • Food coloring Hypothesis #1: (CIRCLE) When we put water and oil together in our lava lamp it will…. separate from each other OR mix together? Question #2: What will happen when we add Alka-Seltzer to the lava lamp liquids? Procedure: 1. Fill a quarter of the bottle with water 2. Fill the rest of the bottle with vegetable oil (almost to the top) 3. Add a few drops of food coloring 4. Break up two Alka- Seltzer tablets in half and put them in one at a time **You should wait for the bubbles to stop before adding more tablets + Hypothesis #2: When we put Alka-Seltzer tablets into the lava lamp the tablets will… rise to the top OR stay on the bottom?

  2. Oil and Water Drop Alka-Seltzer tablet 1. Water and Oil separate into 2 layers. 2. Water = “water loving” & Oil= “scared of water”. 3. Ingredients in Oil make it not attracted to water– so they separate. 4. Oil floats on the top because water is heavier than oil. • Alka-Seltzer tablets dissolve in water. • When it dissolves --forms bubbles • that floated up to the top.

  3. Bubbles go to the top bringing some of the colors with it too. Then the water drops back to the bottom and the water & oil become separated again (into 2 layers).

  4. We found that water and oil _______________have a good relationship and they separate when mixed together. AND we found that Alka-Seltzer tablets go to the ________________ when they are dropped in the lava lamp. MY LAVA LAMP EXPERIMENT BOOK OUR RESULTS & CONCLUSION CONCLUSIONS
