1. BUBBLE GUM
ACADEMY OF INNOVATION

4. PROBLEM
• DO ALL BRANDS OF BUBBLE GUM MAKE BIG
BUBBLES?
• ARE SOME BETTER AT MAKING LARGER BUBBLES?
•WHICH BRAND OF BUBBLE BUM WILL
CREATE THE BIGGEST BUBBLE?

5. HYPOTHESIS
• I BELIEVE THAT ____________________ BRAND OF
BUBBLE GUM WILL CREATE THE LARGEST BUBBLES
COMPARED WITH _____________________ BRAND OF
BUBBLE GUM, BECAUSE
_______________________________________
_______________________________________________ .

6. PROCEDURE
1. OBTAIN TWO PIECES OF GUM (EACH A DIFFERENT BRAND OF BUBBLE GUM)
2. OBSERVE THE GUM AND FILL IN YOUR OBSERVATIONS ON THE DATA TABLE.
3. CHEW GUM “A” FOR 3 MINUTES.
4. BLOW A BUBBLE WITH GUM “A”.
5. USE A STRING TO MEASURE THE DIAMETER (DISTANCE AROUND) OF THE
BUBBLE.
6. USE THE METER STICK TO MEASURE HOW LONG THE STRING IS AND RECORD
IT IN YOU DATA TABLE.
7. REPEAT STEPS 3 – 6 FOR GUM “B”.

9. ANALYSIS/CONCLUSI
ON
• WAS THERE A DIFFERENCE IN THE BUBBLE SIZE BETWEEN THE TWO BRANDS OF
BUBBLE GUM? YES / NO
• WHICH BRAND OF GUM IS THE BEST AT BLOWING BIG BUBBLES?
