Repeat with test tubes 2 and 3. Record data about the size of the bubbles from each test tube

3. Test Tube
Approximate size of bubbles formed 1 2 3

4. Analysis -
Were there any noticeable differences in bubble formation between test tube 1 and 2?
Were there any noticeable differences in bubble formation between test tube 1 and 3?
Results -

5. Questions - Which of the three test tubes was the control?
What were the independent and dependent variable(s) in this lab?
This experiment tested how salt and sugar affected bubble making. Develop a different question related to making bubbles. Form a hypothesis and design an experiment to test your hypothesis.
