3. Research
Sometimes it takes a while to get the balloon to be full of air. Most of the time the
balloons don't pop, but sometimes it does. It pops when you fill up the water bottle
with too much baking soda, and vinegar.
4. Hpothesis
I think if we fill the bottle with 1 cup of vinegar, and put 2
tablespoons of baking soda in the balloon it will have the
right amount of air in it so it won't blow up!
Hypothesis
6. Procedures
First take baking soda, vinegar, an empty plastic water bottle and a balloon.
Then, you take out your water bottle and fill it with about 1 cup and a ½ of
vinegar. Fill the balloon with 3 teaspoons. Put the balloon on the top of the bottle
without spilling the baking soda in the bottle. Then whenever you are ready
dump the baking soda in, and hold the balloon.
7. Results
We did our science experiment, and it turned out great! The first time we put the
baking soda in the balloon and put the balloon on the bottle a little bit of the
balloon ripped. So luckily, we had an extra balloon so we put the baking soda in
the balloon, and put the balloon on the top of the bottle again. This time it didn't
rip! Whenever you were ready you dump in the baking soda. Next, we dumped in
the baking soda, and the balloon filled with air. Nicole, Michael, and I were waiting
for it to pop! The crazy thing is it didn't pop!
8. Conclusion
Our conclusion is that our hypothesis was right, but we did not put in two
tablespoons in the balloon. We just thought that what was in the balloon was good
enough! I also think one cup of vinegar was the perfect amount.When the balloon
was full of air, the balloon was a normal size for a balloon. That is why we think
are hypothesis and experiment was perfect!
