Science... Blowing Bubbles With Gum!

Chewing gum experiment

You will be in groups of 3 students to test the which gum is the best for bubble, stretch and taste.

Aim: To see which bubble gum makes the best Bubbles, has the best elasticity and keeps its taste for the longest.

Hypothesis: I think that the ? will make the largest bubble and have the longest stretch. The ? will have the longest taste.

Equipment:

• 3 different chewing gum brands
• stop watch
• ruler
• graph to record detail.

Method:

1. Place the first piece of chewing gum in your mouth and time how long it takes to keep its taste.
2. Chew the gum and record this time on the chart.
3. Using the same piece of gum blow a bubble. Record on the chart as 'no bubble', 'small', 'medium', 'large'.
4. Test for elasticity. Keep all of the gum in your mouth and see how long you can stretch it. Measure it and record its length.

Type Of Gum	Taste	Bubble Size	Length
Hubba Bubba	3mins +	Medium	980mm
Extra	1min 51s	Small	480mm
PK	1m 46s	Small	300mm

Findings: Hubba Bubba lasted more than three minutes because it's taste lasted very long, it's bubble stretch is medium and it's length was 980mm. Extra's taste lasted 1min 51s, bubble size small and stretch length 480mm. PK's taste lasted 1m 46s, bubble sized at small and stretch length 300mm.

Conclusion: from the experiment I think Hubba Bubba is the best gum to buy when you want a bubble gum. It's the stretchiest and it's taste lasts the longest.
