| My
hypothesis is that the lemon juice, vinegar, pop and alcohol can blow up
the balloon.
|
|
| My
science project question is, can lemon juice, vinegar, alcohol, or pop
blow up a balloon. It tells what I'll be doing
or trying to do during my experiment. It's also easy to take notes and
remember what happened during the experiment. My hypothesis is that all
of them can blow up the balloon. I believe this because they all
fizz and create pressure.
First, I stretch the balloon so the rubber is easier to inflate. Second, I dissolve a teaspoon of baking soda in an ounce of water in the clean, empty soda bottle. Third, pour in and stir the two ounces of which ever liquid. Fourth, quickly fit the stretched balloon over the mouth of the bottle. The balloon should inflate. The results of my experiment were the lemon juice and vinegar blew up the balloon, the alcohol and pop did not. My hypothesis was wrong. Next time I would of used liquids that had more fizz to them. |

1. Stretch the balloon so the rubber is easier to inflate. 2.Dissolve a teaspoon of baking soda in an ounce of water in the clean, empty soda bottle. 3.Pour in and stir the two ounces of which ever liquid. 4.Quickly fit the stretched over thee mouth of the bottle. 5.The balloon should inflate. |
|
| The
results of my experiment were that the vinegar and lemon juice blew up the
balloon but the pop and alcohol did not.The one that blew up the balloon
the most was the lemon juice.
|
|
| My
conclusion is that all of them did not blow up the balloon. My hypothesis was wrong. Air pressure from fizz of the liquid can blow
up the balloon. Next time I would of used liquids with more fizz to them
so the balloon would blow up.
