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?
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.
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).
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
