We did some science. We got everything ready to do an experiment. First we made a list of our materials and wrote a prediction to guess what would happen. What we did first was to put baking soda into a balloon. Then we poured white vinegar into a bottle, it has to be white vinegar, nothing else works. Next we put the ring of the balloon over the top of the bottle, trying to not to get any baking soda in the bottle. Once we had all got our balloons over the top of our bottles we let all the baking soda drop into the bottle and mix with the vinegar. By adding the baking soda to vinegar it caused it to fizz and made the balloons inflate. At the end we wrote a conclusion saying what actually happened.
