BUBBLE LAB

​

Part 1, 2, 3

Hypothesis:

• An answer, based on gathered information for a specific question, that will be tested.

Bubble Lab - Part 1

• Question:

How do you blow the largest bubble?

Hypothesis:

• 1.
• 2.
• 3.
• 4
• 5.

5 things you want to test today!

Results:

• 1.
• 2.
• 3.
• 4.
• 5.

Describe what happened when you tested each hypothesis.

independent variable:

• The factor in the experiment that is changed to test a hypothesis.

(manipulated variable)

dependent variable:

• The factor that changes because of the independent variable or the result that you observe changing.

(responding variable)

constants:

• The factors that remain the same in the experiment.

(controlled variable)

Bubble Lab - Part 2

• Question:

Which dishwashing soap will make the biggest bubbles?

Hypothesis:

Data Table

Analysis:

1. What is a constant? Describe 3 constants in this experiment.
2. What was the independent variable in this experiment?
3. What was the dependent variable in this experiment?
4. Why did we repeat the experiment multiple times?

Conclusion:

Write a conclusion paragraph. Be sure to include:

• the answer to the experimental problem
• evidence (data) to support the answer
• whether your hypothesis was correct or incorrect and why
• describe any relationships, patterns, or trends in the data

Bubble Lab - Part 3

• Design your own experiment, that you can test tomorrow, using only the provided materials.
• Be creative but make sure it’s doable.
• Determine the independent and dependent variable, constants, materials, and procedures for your experiment.
• Use the “Lab Writing Frame” handout for Part 3.
