The student conducted an experiment to create a homemade lava lamp using water, oil, food coloring, and effervescent tablets. They hypothesized that combining these ingredients would produce a lava lamp effect. In the experiment, they added each ingredient in steps to a glass jar. When effervescent tablets were added, they produced gas that caused the colored water to rise up through the oil, mimicking the movement of lava, confirming their hypothesis.

happens.
?

3. QUESTION
What will it happen if we put the water, oil ,food
coloring and effervescent tablets ?

4. HYPOTHESIS
We think that the water, oil, food coloring and
effervescent tablets will do a lava lamp.
Is it true?

5. EXPERIMENT
1. First we put water in the glass
2. Second we put oil into the glass
3. Third we put food coloring into the glass
4. Four we remove well all ingredients
5. Fifth we put the effervescent tablets into the glass
6. Then we finish our lava lamp

6. OBSERVATION
The effervescent tablets do that the water with food
coloring go up to the top. The movement looks like an
erupting volcano

7. CONCLUSION
The water with effervescent tablets produces gas and
we see like drops that go up to the top.
