Mentos Experiment

Today in science our students did some experimenting.  Have you ever heard that Mentos will make a coke spew?  Well, we put it to the test using a variety of sodas and both fruit and mint flavored Mentos.
 
The students started by making a hypothesis.
 
 
Then, they got the experiment set up.
 
Check out the results:
 
 

One group went off a little early, but they were all successful!
 

 
The majority of students thought Root Beer would do the best, but they were wrong!  So, if you decide to try this one at home, we now know you'll need a 2 liter of Diet Coke and a pack of mint flavored Mentos.
 
Students discussed surface tension and the reaction with the ingredient gum arabic.  Scientists still haven't decided exactly what causes the reaction, and neither have our students, but they discussed several possibilities.
 
 
 
 
***PARENTS:***
 
Progress reports came home today!  Please look them over and discuss them with your student.
 
There is no school for students on Monday or Tuesday.  Tuesday is set aside for parent teacher conferences - you should have already been contacted with an appointment time if one is needed.
 
  We'll see everyone on Wednesday!  (6th graders, don't forget your social studies assignment that is due Wednesday.)
 
Have a great weekend!
