Question

1. give examples/detail as to why you think in #14 what squidwards conclusion should be?
2. are the results reliable? why or why not?
3. any suggestions of what squidward could have done differently to gain better results?

super bubbles
patrick and spongebob love to blow bubbles! patrick found some super bubble soap at sail - mart. the ads claim that super bubble soap will produce bubbles that are twice as big as bubbles made with regular bubble soap. patrick and spongebob made up two samples of bubble solution. one sample was made with 5oz of super bubble soap and 5oz of water, and the other was made with 5oz of regular bubble soap and 5oz of water. patrick and spongebob used their favorite bubble wands to blow 10 different bubbles and did their best to measure the diameter of the bubbles as they popped on the table. the results are shown in the data table below.

1. what did the super bubble ads claim?
2. what is the independent variable?
3. what is the dependent variable?
4. look at the results in the data table.

calculate the average diameter for each bubble solution.
super bubble = ___ cm
regular soap = ___ cm
what do you think spongebobs and patricks conclusion should be?

1. are the results reliable? why or why not?

(diameter in centimeters)

bubble	super bubble	regular soap
2	10	5
3	12	16
4	18	14
5	22	11
6	13	12
7	16	11
8	18	15
9	15	15
10	12	6

Explanation:

Step1: Recall the claim

The Super - Bubble ads claim that Super Bubble Soap will produce bubbles that are twice as big as bubbles made with regular bubble soap.

Step2: Identify independent variable

The type of bubble soap (Super Bubble Soap or regular bubble soap) is the independent variable as it is the variable that is being changed or manipulated in the experiment.

Step3: Identify dependent variable

The diameter of the bubbles is the dependent variable as it is the variable that is being measured and is expected to change based on the type of soap used.

Step4: Calculate average for Super Bubble

Sum of Super Bubble diameters: \(15 + 10+12 + 18+22+13+16+18+15+12=151\). Average diameter of Super Bubble \(=\frac{151}{10}=15.1\) cm.

Step5: Calculate average for Regular Soap

Sum of regular soap diameters: \(10 + 5+16+14+11+12+11+15+15+6 = 115\). Average diameter of regular soap \(=\frac{115}{10}=11.5\) cm.

Step6: Draw conclusion

The average diameter of Super - Bubble is not twice that of regular soap. So, SpongeBob and Patrick's conclusion should be that the claim made by the Super - Bubble ads is not supported by their experiment.

Step7: Evaluate reliability

The results may not be very reliable. Reasons include: small sample size (only 10 bubbles of each type), potential human - error in measuring the diameter of the bubbles as they popped, and lack of control over other factors like blowing force and environmental conditions (e.g., wind, humidity).

Answer:

1. The Super - Bubble ads claim that Super Bubble Soap will produce bubbles that are twice as big as bubbles made with regular bubble soap.
2. The type of bubble soap (Super Bubble Soap or regular bubble soap).
3. The diameter of the bubbles.
4. Super Bubble = \(15.1\) cm; Regular Soap = \(11.5\) cm; Conclusion: The claim made by the Super - Bubble ads is not supported by their experiment.
5. The results may not be very reliable. Reasons include small sample size, potential human - error in measurement, and lack of control over other factors like blowing force and environmental conditions.
