Questions
Are Mentos the only thing that makes coke fizz?
What inside Mentos makes coke fizz?
What coke is better to use? Regular or Diet.Slide3
Research
Both Mentos and Baking soda makes coke fizz
Mentos has sodium in it
Coke has carbon dioxide
Diet coke causes a better reaction, and regular coke makes a big sloppy mess
Mentos
Soda
Fizz
Independent variable – Mentos
Dependent – Coke Slide4
Hypothesis
The carbon hydrates and water molecules (in coke) will cause the coke to fizz up. Sodium and
M
entos makes it fizz too. With the three things I'm assuming that the fruit
M
entos will have the biggest eruption.Slide5
Experimental steps
Step 1 – Set up the coke,
M
entos, and baking soda
Step 2 – separate the things so everything doesn't get wet
Step 3 – Take out one coke and 3
M
entos, or a spoon full of baking soda
Step 4 – Once your done with every thing hose down table Slide6

Analysis
Both Mentos gave same reactions, but both eruptions were quick, short, and not so much fizz came out. With the baking soda the eruption started out small and grew in size and lasted longer.Slide8
Conclusion
My hypothesis was partially wrong, but also right. The carbohydrates and sodium worked together to erupt. Both fruit Mentos and mint Mentos made the same height eruption and lasted the same. The baking soda had a longer lasting eruption, and was taller than than the others.
