I don't know how it came up, the mentos and coke thing. One day the kids and I found ourselves on you-tube watching videos of mentos and coke 'explosions.' We had to try it ourselves.
We don't do anything fun around here, so of course I had to turn this too into schoolwork. I made up some sheets that had the steps to the scientific process. I plugged in some of the information for them since this is our first time using this.
Title: Coke and Mentos
Question: What will the reaction be when a mentos is dropped in a bottle of coke.
Prediction: ________ (they all wrote their own) Bee: "It will spray really high."
Materials: a 2 liter of diet coke, 1 mentos
Procedure: Drop mentos in the open bottle of coke.
Data: (their drawings of the observations of before and during)
We took to the street for this one.
Conclusion: ________________ (they each wrote their own) Bee: "The pop shot up really high."
Every time I hear the word(s) You-tube, I think of that episode of The Office where Michael says, "I've gotta get those folks from you-tube down to film this!" Here's our video of our experiment with the neighbors out watching too. You can only see it here, it's not on you-tube.
