4th grade science project: bubble gum

Last year I wrote about Tiger's science project with the mentos and coca-cola here.
It seems to have been well received as it has become my most frequently visited blog post.

This year Dragon is in 4th grade and we haven't gotten to the part of the year where he creates a science project, but in class they discussed a bubble gum project that sounded fun.  So we decided to give it a try at home:

the question: which kind of bubble gum makes the biggest bubble?

We went to the local CVS and picked out 4 kinds of bubble gum.

We invited two friends from MLyon's 1st grade over to help us.  With Tiger, Dragon & MLyons that made 5 different scientist helping with the project.
 Next step, make a guess (hypothesis) as to what you think will be the answer to the question.  Tiger & Dragon guessed that the Hubba Bubba Max would make the biggest bubbles.  C. L. and MLyons guessed that the Bubble Gum Tape would make the biggest bubbles.

We started with the Hubba Bubba Bubble Tape, everybody received a piece roughly 1 1/2 to 2 inches long.  It was decided that this was not enough gum to make a bubble with.  So they each received another piece.  We measured bubbles with string.

Then we tried the Hubba Bubba Max.  This is bubble gum, big easy bubbles.  Interestingly 1/2 of them like the taste of the tape better than the taste of the Max.

Then we tried the Orbitz.  Nobody liked the taste.  They all decided it tasted like medicine.  And nobody could blow bubbles.  Not even with two pieces in their mouth.

Last we tried the Trident Layers.  "WOW! This tastes awesome!" Exclaimed L.  A few small bubbles were blown but not many.

keeping track, we cut the measuring string and taped it flat

Conclusion: It was decided that the Max is best for blowing bubbles.  Our scientists were able to blow more bubbles, and bigger bubbles with the Hubba Bubba Max than with any of the other kinds of gum that we tried.

What a great idea! I plan on using this in my 4th grade classroom to reinforce the scientific method!
