Volcano Experiment By:Gage Walters 12-3-14

Scientific Questions How to make a homemade volcano and how does it work?

topic I chose this topic because I like volcanos and I would like to make my own volcano

hypothesis If I use 2 tablespoons of baking soda the volcano reaction will be more explosive.

variables I will be changing the amount of baking soda in trial 2.

Procedure -created volcano -got supplies together -placed volcano in bath tub -added vinegar and baking soda -measured and recorded data -repeated steps 1-5

DATA trial 1 trial 2 1tbs of baking soda 1 cup of vinegar 1 tbsp of dish soap When the baking soda was added to the mixture of vinegar and dish soap the eruption began. When the eruption ended there was slightly less than 1 cup of the vinegar mixture leftover in the volcano trial 2 2 tbs of baking When the baking soda was added to the mixture of vinegar and dish soap the eruption began. When the eruption ended there was approximately 1/4th of a cup of the vinegar mixture leftover in the volcano.

conclusion 1.What is the best way to make homemade volcano and increase the power of the eruption. 2.By adding baking soda to the the mixture of vinegar and baking soda I was able to create an eruption 3.By increasing the amount of baking soda i was able to increase the power of the eruption

conclusion 4.My hypothisis was correct because if i add 2 table spoons of baking soda the volcano had a bigger eruption 5.I learned in this experiment it does not

conclusion matter about vinegar it matters about baking soda and how much you put in your volcano. 6.With 1 tablespoon of baking soda there was very little eruption.I fixed it by adding more baking soda which made a greater eruption
