Bubble Investigation Experiment

Plan a fair test to find out whether adding sugar changes how long a bubble lasts. You will need adult-approved bubble solution ingredients, a timer and the same bubble wand for each test. Do not taste the mixtures. Clean up spills promptly.

Plan a fair test

Mere and Hana want to find out if sugar helps bubbles last longer. They will compare two mixtures and keep other conditions the same.

1.Which question are Mere and Hana investigating?

Does sugar change how long a bubble lasts?
Which colour is the nicest?
How many people can blow bubbles at once?

2.They use 100 mL of water in each mixture. Mixture A has 20 mL of dishwashing liquid. Mixture B has 100 mL of water, 20 mL of dishwashing liquid and 1 teaspoon of sugar. What is the one planned difference between A and B?

3.Name two things the pair should keep the same to make this a fair test.

4.Before testing, Mere predicts Mixture B will make bubbles last longer. Is this a prediction or a result?

A prediction
A result
A conclusion based on measured evidence

Record the results

For each trial, use the same wand and start the timer when the bubble leaves the wand. Stop timing when it pops. Record times in seconds.

Mixture

Trial 1

Trial 2

Trial 3

A: no sugar

B: sugar

5.After recording all three trials, calculate the mean (average) lifetime for Mixture A. Add its three times and divide by 3.

6.Compare the mean lifetimes of mixtures A and B. Which lasted longer in your results? Include at least one piece of evidence from your table.

7.True or false: If one bubble from Mixture B lasts longer than one bubble from Mixture A, that proves sugar always makes bubbles last longer.

TrueFalse

8.Write a conclusion that answers the investigation question. Use your results and say whether they support Mere's prediction.

9.Suggest one improvement or one new question for a follow-up bubble investigation.
