The Scientific Method

Title -  Fizzy Drink and Mentos Experiment
Purpose: What do you want to learn/find out?
Which drink has the biggest reaction to the mentos.

Hypothesis: Try to predict the answer to the problem. Another term for hypothesis is ‘educated guess’. This is usually stated like ” If I…(do something) then…(this will occur)
I think the biggest reaction might be the one that is desperately reacted to the mentos. I think it might explode a little bit because there was not that much liquid in it.

Materials: List everything you will need to conduct your experiment.
We used five different sodas:
Coke, Diet Coke, Fanta, L&P, 7 Up, and Pepsi
Packets of Mentos

We used sellotape to put the mentos in it. After that we went outside so the sodas won’t fall out to the carpet. We then putted the mentos inside each one of the fizzy drinks.

Experiment procedure: The fun part! Design a test or procedure to confirm or disprove your hypothesis. Write down each step so that someone else could do the same experiment.
  1. Get a pair of scissors or any kind of sharp object and create an hole in the middle of the soda cap.
  2. Get a piece of sellotape and stick 5 mentos onto it.
  3. Place the sticked mentos inside each of the caps and leave it there for someone to pull the sellotape to see how high it can go.
Don’t forget to measure with a ruler.

Analysis/Data: Record what happened during the experiment.
When I looked at the mentos go down to the liquid, it fizzed up. Also the carbon dioxide released from the bottle which is also called gas. All of the sodas exploded a little bit, maybe because there was not that much liquid in it.

Conclusion: Review the data and check to see if your hypothesis was correct.
As I was saying about the prediction not all of the foam went up because it failed. So I was right about the mentos and fizzy drink experiment.

This is a scientific method I was working on. I have been working on it for about 25 minutes and this is about the experiments we had during the past few weeks. I hope you enjoy.
